New Engineering Division Director an Expert in Solid State Physics

By Monica Friedlander

Yaffa Marianna Tomkiewicz, a scientist internationally recognized for her work in solid state physics, has been appointed director of Berkeley Lab's Engineering Division. The first woman to head the division, she replaces outgoing director Edward L. Burgess, who has held the position since 1989.

"Dr. Tomkiewicz has demonstrated a high level of technical accomplishments as a scientist and as an engineering manager," said Lab Director Charles Shank in announcing the appointment. "I look forward to working with her in assuring that the Laboratory continues to have world-class engineering support for our programs."

Tomkiewicz's experience includes more than two decades at IBM, a career which culminated in the development of the highly acclaimed magnetoresistive head, which allowed for a great increase in disk storage capacity. Her work at IBM spanned the spectrum of both basic and applied physics and chemistry --from research into solid state physics, to product development, management of technical programs, and the introduction of the magnetic heads to the computer storage business. Her position at the Lab represents Tomkiewicz's first venture into government research.

"The breath of technology here at Berkeley is mind-boggling," she said. "This is a very interesting transition for me from industry to government-managed research. The people I have met here are very exciting and knowledgeable, and the facilities are very impressive. I look forward to starting some collaborations with colleagues in Berkeley."

A native of Czechoslovakia, Tomkiewicz earned her Ph.D. at Hebrew University of Jerusalem, Israel, before starting her career in the United States. While she takes great pride in her achievements, she is more than eager to share credit with the teams of scientists she has led along the way. In fact, she places high value on her ability to attract quality people to her projects.

"There are a lot of experiences which I can bring from industry," she said, "including the ability to attract funding and hire good people in a very competitive market, which I believe this is."

Tomkiewicz started her career in basic research in the early and mid-1970s, working in the area of solid state physics, particularly with organic conductors and conducting polymers. While at IBM, her interests shifted to applied physics. Her work quickly progressed from development of packaging technologies, to manufacturing research, and eventually to the development of the magnetoresistive heads. This development paved the way to position IBM in a leadership role in high density storage.

"Even now, eight years later," she said, "this development is still in the forefront of technology." The magnetoresistive heads led to a dramatic increase in computer disk storage density--that is, the amount of information that can be stored in a given area, which she estimates is now going up by approximately 60 percent each year in the computer industry.

Following this achievement, Tomkiewicz went on to manage an engineering group at Quantum Corp., where she oversaw the development and manufactoring ramp-up of the magnetoresistive heads. In 1995 she formed G.R. Enterprises, a technology and consulting company in the arena of magnetic heads.

Her predecessor in the Engineering Division, Ed Burgess, is returning to his work as project manager for the Dual Axis Radiographic Hydrodynamic Testing project.

"Throughout, Ed has been a dedicated manager," said Director Shank, "uncompromising in matters of excellence and integrity." During his years as division director, Burgess was involved with such prestigious projects as the Keck Telescope, the STAR Detector, the Human Genome Center, and the Advanced Light Source.

Tomkiewicz said she was surprised to find out she is the first woman to head the division, an honor she does not take lightly.

"I've always believed that women can perform as well or better than men," she said. "But I always wanted to be treated as one of the guys, and I refused to be regarded as a token person. I really look forward to performing well because it would give a good example to all competent women."

She said she believes that as a woman she had more opportunities for professional growth in the United States than she would have had in most places in the world. She speaks fondly of her adopted country.

"Nobody was ever concerned about my Israeli accent," Yaffa Tomkiewicz said. "Nor did I have to change my name--which is not to be confused with the famous product of Israel." Jaffa oranges, that is.

Lab-Developed Technology Improves Semiconductor Manufacturing Process

By Allan Chen

The semiconductor industry's process engineers are always searching for new technologies to reduce the cost and number of defects, and improve the performance of its integrated circuits. Berkeley Lab's Ka-Ngo Leung has developed and patented a technique that can improve the semiconductor manufactoring process.

Semiconductors are the materials from which most integrated circuits such as microprocessors and dynamic random access memories--the critical components of desktop computers and many other electronic devices--are made. The primary application of Leung's new "selective ion source" technology will be in the manufacture of flat-panel displays (FPDs).

The winners of the race to bring down the cost and reduce the defect rate of these complicated semiconductor-based display devices will reap a huge economic reward, since FPDs are expected eventually to dominate the market for high-resolution displays. Considerable research in the United States, Japan, Germany and elsewhere is aimed at developing the technology for inexpensively manufacturing high-quality FPDs.

"Flat-panel displays consist of many pixels," says Leung, who heads AFRD's Plasma and Ion Source Technology Group. "Each pixel turns on and off individually, and is controlled by transistors, which are formed from semiconductors consisting of silicon `doped' with phosphorus or boron." A pixel is a picture element, one of the dots forming a digitized image. In doping, ions are added to the silicon in order to produce desired semiconductor properties.

One way to dope a layer of silicon with phosphorus, arsenic or boron ions is to aim a stream of dopant ions into the silicon, a process called ion implantation. The manufacturing process must ensure that the dopant is pure and as uncontaminated as possible by unwanted ions.

"Conventional implantation might start with a beam of phsophorus or boron scanning the silicon wafer to dope it uniformly," Leung says. "However, flat panel displays start with a panel of glass that is too big to use the conventional method effectively.

"Therefore, a technique called ion shower is used. You employ a large beam of phosphorus or boron. You immerse this big panel of glass in the shower. This implants the whole panel with the dopant. To do this you need a big ion source."

The ion source generates a stream of dopant ions such as phosphorus by starting with a phosphorus-containing gas like phosphine (PH3), Leung says. However, phosphine is so toxic that it is always sold heavily diluted, often in a mixture of 95 percent hydrogen gas and five percent phosphine. "When you put this gas into a conventional ion source, what do you get? Most of the ions coming out are hydrogen."

This creates two problems. One is that the energy of the beam is so high that the silicon-coated glass blank is heated too much by the accelerated hydrogen ions (or other unwanted ions in the mixture), causing damage to the glass surface. A second problem is damage caused by the buildup of excessive electrical charges in the plate from the unwanted ions. The damage can be significant enough to warrant throwing out the plate--an expense that substantially raises the cost of manufacture.

Leung's solution was to develop an ion source technology that uses just enough energy to selectively ionize only the phosphorus-containing gas, and not the hydrogen gas. This eliminates most of the unwanted impurities from the ion stream because they are electrically neutral, and reduces both the excess heating and the charging problem.

The technology also solves another problem. "Conventional ion sources use a tungsten filament to inject the gas containing the dopant with electrons," he says. "However, the tungsten is an impurity that is easy to ionize, a source of contamination. So we developed a technology to inject electrons without tungsten that instead uses a principle called radiofrequency (RF) induction discharge. We create plasma using RF induction discharge and then inject electrons into the main chamber to ionize the source gas," he says. "The device is called an RF plasma cathode."

Leung also has another invention which consists of an apparatus for creating a large-diameter ion beam from a small-diameter diverging beam. In conjunction with the selective ion source, this invention can be used to generate a beam appropriate for ion implantation of large areas of material such as those used in flat-panel displays.

Administration budget proposal good news for Lab

By Reid Edwards

A preliminary analysis of the Clinton Administration's FY1998 budget proposal, introduced last week, indicates generally good news for Berkeley Lab. In the broader context, the budget is consistent with the general Federal R&D message. Office of Science and Technology Policy Director John H. Gibbons, speaking Feb. 6 on the budget, noted that this was the fifth year in a row for proposed increases in science and technology.

The Department of Energy budget proposal is for $16.6 billion--a 2.6 percent increase over the FY97 total of $16.2 billion. In addition, DOE is proposing an additional $2.6 billion in "forward funding" for new and ongoing construction projects. This would mean, if approved by Congress, approval for the full construction budget, even though funds would still be provided on an annual basis for these projects.

There is particularly good news for the Office of Energy Research, which, this time last year, was facing a reduction of $200 million per year for the next three years. In her budget message, ER Director Martha Krebs notes that the Administration has now designated ER's programs in high energy and nuclear physics, basic energy sciences, and biological and environmental research as "priority programs, consistent with the National Science Foundation and the National Institutes of Health." This designation has essentially meant the disappearance of these reductions, and a FY98 budget proposal that is $32 million higher than for FY97.

There are three major new efforts within the Energy Research budget that will involve Berkeley Lab. The first is the National Spallation Neutron Source at Oak Ridge National Laboratory, for which the budget proposes $23 million in pre-construction funds. Berkeley Lab is very involved in the initial design efforts, and will continue this involvement as the project moves into construction.

The second effort is the Next Generation Internet project, a three-year, $100 million per year effort to make the Internet faster and more productive for users around the nation. ER has $35 million in their proposed budget, second only to the Defense Department. Berkeley Lab is expecting to play an important role in the definition and implementation of this program.

Finally, $35 million is proposed in the budget to accelerate the U.S.-CERN partnership on the Large Hadron Collider, the next major particle physics facility. Berkeley Lab has a key role in the ATLAS experiment at this facility, both in developing the science and in building some of the instrumentation.

The ER budget also contains other increases that are good news for Berkeley Lab. The Presidential Facilities Initiative, first started in FY96 to provide more support for operating DOE's national user facilities, is given a boost in the FY98 request, resulting in a proposed $2 million increase in the ALS budget. There is also a proposed increase of $7 million apiece for the DOE genome sequencing effort and the NABIR program in bioremediation. Finally, other changes include significant increases in the energy-efficiency research programs which, if approved by Congress, would mean sizable increases in Berkeley Lab's programs.

All in all, within the tight fiscal climate in Washington, D.C., the Clinton Administration's budget proposal is a very good start. It does, of course, face many congressional hurdles. The examination process has already begun by congressional committees, and will accelerate over the next few months. There is in Washington, however, at least the beginning of a new, positive working relationship between the Administration and Congress. This portends, I believe, a budget process that may be less adversarial and, in the end, result in a budget completed before the end of the current fiscal year and close to the Administration's projected budget for Berkeley Lab.

Langevin-Joliot Visit Marks Centenary of the Discovery of Radioactivity

Dr. Hélène Langevin-Joliot, granddaughter of Marie and Pierre Curie, visited UC Berkeley Feb. 11 and 12 to celebrate the centenary of the discovery of radioactivity. During her visit, she gave two heavily attended talks, speaking about past and present challenges of radioactivity, the role of women in science, and recalling the legacy of her parents and grandparents, perhaps the most honored family in the history of science.

Marie and Pierre Curie were jointly awarded the 1903 Nobel Prize in Physics for their work on radioactivity (along with Henri Becquerel, who discovered radioactivity in 1896). Marie Curie won a second Nobel Prize in Chemistry in 1911 for her discovery of the radioactive element polonium. Langevin-Joliot's parents, Frederick Joliot and Irene Joliot-Curie, discovered artificial radioactivity and were jointly awarded the 1935 Nobel Prize in Chemistry.

A Nobel Laureate closer to home, Berkeley Lab's Glenn Seaborg prompted Langevin-Joliot's visit when he was in France last fall to receive the Honoris Doctorat Causa from the University of Paris-South, where Langevin-Joliot was a professor at the Institute of Nuclear Physics.

Langevin-Joliot has made several contributions in the field of radioactivity, and has recently undertaken a mission to urge greater numbers of women to actively pursue careers in scientific research and teaching.

Researchers Find "Smoking Gun" to Support Asteroid Theory of Dinosaur Extinctions

Scientists announced this week that they have found "proof positive" that a huge asteroid smashed into Earth 65 million years ago. The find comes 18 years after Berkeley Lab's Luis Alvarez and his son Walter (a UC Berkeley geologist) first theorized that such an impact had occurred, and was responsible for the death of the dinosaurs.

"We've got the smoking gun," said Richard D. Norris of the Woods Hole Oceanographic Institution, the leader of an ocean drilling expedition that drilled 300 feet beneath the floor of the Atlantic Ocean floor in search of asteroid evidence. "It is proof positive of the impact."

Norris reported that the expedition had recovered layers of sediment that paint a picture of the earth before, during, and after the impact.

Norris said the deepest layers of sediment contain fossil remains of many animals and came from the ocean at a time just before the impact. Just above this is a layer with small green glass pebbles, thought to be ocean bottom material instantly melted by the heat of the impact. Next was a rusty brown layer which Norris said is thought to be from the "vaporized remains of the asteroid itself."

Just above the brown layer is two inches of gray clay that provide evidence of a nearly dead world. "It was not a completely dead ocean, but most of the species that are seen before (prior to the impact) are gone," said Norris. This dead zone lasted about 5,000 years, he said, and then the core samples showed evidence of renewed life.

Robert W. Corell, assistant director for Geosciences of the National Science Foundation, said the core samples are the strongest evidence yet that an asteroid impact caused the extinction.

"In my view, this is the most significant discovery in geosciences in 20 years," he told the Associated Press. "This gives us the facts of what happened to life back then. I would certainly call it the smoking gun."

When Luis and Walter Alvarez first proposed that the dinosaurs disappeared because of a massive asteroid hit, their theory had few supporters. Berkeley Lab researchers Rich Muller, Frank Asaro, and Helen Michel became involved in the project and provided scientific as well as moral support for the then-controversial hypothesis. In 1989, 10 years after the theory was promulgated, scientists found evidence of a huge impact crater north of Chicxulub, on Mexico's Yucatan Peninsula. Later studies found evidence of debris washed out of the Gulf by waves that went inland as far as what is now Arkansas.

This week's finding--core samples taken off the coast of Florida--provides further confirmation that an asteroid of six to 12 miles in diameter smashed into Earth, killing off up to 70 percent of all species on Earth. -- Jeffery Kahn


Comet Hale-Bopp Co-discoverer to Speak at LHS

Alan Hale, co-discoverer of Comet Hale-Bopp, will share the excitement of his discovery in a public lecture at 7:30 p.m. on Wednesday, Feb. 26, at the Lawrence Hall of Science. The talk is presented by UC Berkeley's Center for Particle Astrophysics.

Comet Hale-Bopp will be at its peak of visibility this spring, and is expected to surpass the thrill of last year's Comet Hyakutake. Offering his perspective about the comet and how to observe it, Hale will also discuss the formation of the solar system and current efforts to identify potential Earth-impacting objects, such as asteroids and comets.

Hale is founder and director of the Southwest Institute for Space Research in Cloudcroft, N.M., and an advocate for the advancement of scientific literacy. Following his talk, he will be available to sign copies of his book, "Everybody's Comet: A Layman's Guide to Comet Hale-Bopp."

The talk is recommended for ages 12 and up. Admission to the lecture is free; seating is on a first-come, first-served basis. The Lawrence Hall of Science is located on Centennial Drive, below Grizzly Peak Blvd. in Berkeley.




Central Stores Offers One-Stop Shopping

By Monica Friedlander

They fill three large rooms in Bldg. 78, stacked in neatly-numbered shelves and cubbyholes filling every inch of room and wall space. Ten thousand items in all: pipes, nuts and bolts, plastic gloves, batteries, glassware, tools, electrical wires, tape, computer diskettes, janitorial and medical supplies.

"It's like a mini-Home Depot," says Jacques Pryor, who has worked in Stores for the past 11 years. All of these supplies are available to Lab employees with a simple phone call.

At one time, Lab supplies were split between Craft Stores and Central Stores--one on the Hill, the other off-site. The two groups later merged and changed locations a couple of times. But things have settled down, and Central Stores, located in Bldg. 78 (site of the old Craft Stores) is the Lab's one-stop supplies solution for most items. Here are the few exceptions:

All other supplies, including Lab stationery and other Lab documents, are available at Central Stores, and can be ordered by calling X5087.

Orders can also be placed by fax at X4211, or, for Unix users, through Stores' computerized online database. Available through the menu-driven Toolkit system, this comprehensive listing of Stores items can be accessed on ux10 by anyone with a Unix log-in. (To access it, type "focmenu" at the prompt to log onto the Focus application, then click return. Once in the Toolkit menu, choose Stores and follow on-screen directions. You can apply for a Unix account at

Under normal circumstances, Stores orders take up to a week to be filled from the time the order comes through until delivery by Transportation. Rush orders may be placed for an additional charge, and will be hand-delivered.

Stores receives up to 100 orders a day, which keeps the four-person staff busy ensuring that Lab customers receive their supplies on time. "We make an effort to make sure that all customers get what they want, when they want it," Pryor says.

Researchers Seek Volunteers

Male employees with past military experience are being sought to provide a urine sample to establish a baseline for research being done by Dr. Ed Kaplan and his group at Brookhaven National Laboratory (BNL), for the Defense Special Weapons Agency in the U.S. Department of Defense. The agency needs to determine whether veterans exposed to radioactive fallout from nuclear testing in the 1950s and `60s show any greater internal dose of plutonium-239 (239Pu) than people who were not similarly exposed.

Volunteers should be U.S. veterans over 50 years of age with no renal disease or known exposures to plutonium. For more information, contact Connie Grondona at X6266.




Science and Technology Conference Draws Hundreds of Oakland Teachers

Annual BASTEC event coordinated by Berkeley Lab's Center for Science and Engineering Education

By Monica Friedlander

More than 600 teachers--over one third of the math and science teachers in Oakland's public schools--attended the sixth annual conference sponsored by the Bay Area Science and Technology Education Collaboration (BASTEC), which was held Feb. 7 at Skyline High School in Oakland. Berkeley Lab is a member of BASTEC. The day-long event featured more than 70 workshops highlighting innovative math and science projects in the Bay Area, as well as hands-on activities and exhibits focusing on resources and training opportunities for educators.

Mina Bissell, director of Berkeley Lab's Life Sciences Division, delivered the keynote address on the topics of breast cancer and cell biology and the role of women in science. Eileen Engel, precollege program coordinator for the Lab's Center for Science and Engineering Education (CSEE), received a plaque from Dale Koistinen of the Oakland Unified School District for her "commitment and dedication to BASTEC and Oakland youth."

Topics covered at the conference included core curriculum issues, environmental projects, innovative programs and resources on the Internet. The conference was coordinated by CSEE's Karin Levy.

BASTEC is a collaboration between the Oakland Unified School District (the sixth largest in the state), the Bay Area's four Department of Energy national laboratories, colleges and universities, businesses, and community organizations.

Health Notes

Tick Bite a Thing to Avoid

Brought to you by the Health Services Department

Many Bay Area parks are posting warnings about tick hazards. Several diseases, including Lyme disease, Rocky Mountain spotted fever, and tularemia, can be transmitted by ticks. Lyme disease is the most common tick-borne disease in California, and the Western black-legged tick (Ixodes pacificus) has been identified as the carrier.

Both Alameda and Contra Costa counties have conducted annual tick surveys for the past several years. Tick populations vary from county to county; in most locations, less than one percent, if any, of these ticks actually carry Lyme disease. One exception is the Bollinger Canyon area, with 8.4 percent, according to the Contra Costa County Mosquito & Vector Control District.

The risk to people is relatively low as long as you are aware of the proper methods to avoid tick bites, and promptly remove any ticks that may have attached. Research shows that it usually takes 12 to 24 hours for the bacteria that cause Lyme disease to be transmitted.

Symptoms of Lyme disease include a rash, fever or flu-like symptoms. If you have been bitten by a tick and notice any of these symptoms, contact your physician. Both the Alameda County Vector Control Services and the Contra Costa Mosquito & Vector Control District provide a tick identification service and can arrange to have ticks tested for Lyme spirochetes (see end of article).

Health Services has pamphlets about Lyme disease prevention, available by calling X6266. Following are some tips to avoid tick bites, and phone numbers for tick identification.

UC Botanical Garden a Haven for the Work Weary

By Mary Bodvarsson

It started as a small wildflower garden on the UC Berkeley campus in 1890. More than 100 years later, UC's Botanical Garden has spread across 34 acres of varied terrain in Strawberry Canyon, beckoning visitors from around the world. They come to study the Chinese medicinal herb garden, enjoy the huge collection of cactus and succulents, and get a first hand look at one of the largest holdings of plant species in the country.

For Berkeley Lab employees, the garden is a brief hike or shuttle bus ride from the Lab's Strawberry Canyon gate, making it an enticing place to have lunch, take a stroll in the sun, or grab a snooze in the shade.

The garden was begun by one of UC Berkeley's first botany professors, Edward L. Green. He, along with student Willis Jepson (for whom Jepson Herbarium in the Valley Life Sciences Bldg. is named), planted a teaching garden near Giannini Hall. The garden moved to its Strawberry Canyon home in the 1920s. A few of the original trees remain at the site of the first garden.

The plants in the Botanical Garden are arranged geographically for the most part; the herb and succulent gardens are among the exceptions. The Garden is the fifth largest in the United States in terms of species, with 13,000 at present.

Until this year, visitors to the Garden enjoyed free admission. However, in January, to bring the Garden in line with the campus' other museums, the University began charging an entrance fee most days. Thursdays, the traditional free day at several other campus museums, are also free at the Garden.

Entrance fees are $3 for adults ($2 for seniors), and $1 for children 3-18 years. UC Berkeley students are admitted free. The Garden also offers individual and family annual passes ($20 and $30). You may also join the Friends of the Botanical Garden for $35 (individual basic) or $50 (dual basic) per year, which includes discounts at selected nurseries, early entrance to the annual plant sales, discounts to special events, classes, etc. Annual passes and memberships may be purchased at the entrance kiosk. Garden hours are 9 a.m. to 4:45 p.m., Monday-Sunday.

New fee system takes nothing away from garden delights
