LBL team taps SSC know-how for electronics applications

By Lynn Yarris, [email protected]

Technology used in the development of an ion source for the Superconducting Super Collider is now being applied to the electronics industry.

LBL's new Ion Beam Technology (IBT) group has turned its scientific know-how to developing ion beam projection lithography, a processing technique that could play a central role in the future production of computer chips and microelectronic-based flat panel displays.

Optical lithography, the use of a beam of visible light to etch integrated circuit patterns onto the surfaces of computer chips, is a multibillion dollar industry that was once ruled by the United States. Domestic chip makers hope to reclaim their former pre-eminence with the next generation of integrated circuits which will feature patterns too small to be etched from beams of visible light. Production of these chips will require lithography that uses beams of ions or x-rays.

The most promising route for using either ion beams or x-rays to produce integrated circuits is a technique called projection lithography. In this approach, a beam passing through a stencil-like mask projects a circuitry pattern onto the surface of a semiconductor wafer. Although x-ray projection lithography is currently at a more advanced stage of development than ion beam projection lithography, ion beams offer certain advantages that make them an attractive alternative.

"Ion beams can be used on a variety of surface shapes whereas x-rays can only be used on flat surfaces," says principal investigator Ka-Ngo Leung, a physicist in the Accelerator and Fusion Research Division (AFRD). "An ion beam source is also much less expensive than the best source of x-rays, which is LBL's Advanced Light Source."

The major components of an ion beam projection lithography system are the source that produces the ion beam and the transport column and electrostatic lenses that accelerate and focus it through a mask and onto the surface of a wafer. For the ion source component, Leung and his colleagues are developing a radio frequency (rf)-driven ion source similar (though smaller) than the source they were developing for the SSC.

An rf-driven ion source consists of a chamber inside which a radio frequency electric field transforms a gas of hydrogen or helium into a plasma. The plasma, which is confined within the chamber by a multicusp magnetic field (named for the shape of its force field), contains electrons and both negative and positive ions, but only the positive ions are extracted and formed into a beam.

"An rf-driven ion source is simple to make, rates high in all aspects of performance, and is easily adapted to an automated operation," says Leung. "Its lifetime is practically unlimited, which means it is economical, and it can provide the cold (low energy) ions that lend themselves to forming an intense and easily focused beam."

Leung's group is working now on optimizing the geometry of their rf-driven ion source to maximize the current and the stability of the beam it generates. In ion beam projection lithography, an intense, stable beam is one of the keys to producing a clear, sharp image on a wafer. The other crucial factor is the system of lenses that focus the beam.

Leung and his colleagues are participating in a CRADA that LBL signed last fall with the Advanced Lithography Group (ALG), a Maryland-based consortium of private industry, government laboratories, and universities. The objective of the CRADA is to develop a U.S. capability for ion-beam projection lithography by the year 2000.

The ALG group will use a beam "cross-over" technique in which the mask and a series of electrodes serve as converging and dispersive lenses. An ion beam expands in size as it emerges from the source so that it can illuminate the entire mask. After passing through the mask, the ions in the beam are focused down to a point where they cross over one another and begin expanding again before they strike the wafer and recreate the image of the mask. With this technique, the ALG group can reduce the size of the pattern that is transferred from the mask to the wafer as much as ten times.

Leung's LBL colleagues on this project include Chun-Fai Chan, Wulf Kunkel, Bud Leonard, Tom McVeigh, Margit Sarstedt, Steve Wilde, and Don Williams. UC Berkeley students who are participating on this project include Paul Herz, Yvette Lee, Luke Perkins, Dick Pickard, and Mike Weber.

Women in Science & Engineering Seminar

Deborah Charych, a principal investigator with the Center for Advanced Materials in the Materials Sciences Division, will speak at the next Women in Science and Engineering Seminar. Her presentation, titled "Teaching Poly New Tricks: Polymeric Chameleons Based on the Biological Membrane," is scheduled for 12:10-1:15 p.m. on Monday, March 13, in Bldg. 70A-3377. All employees are invited to attend; refreshments will be served at noon.

Charych will discuss a relatively new approach towards the synthesis of new materials which looks to nature for inspiration. New polymeric materials have been developed with tailored biological activity that resemble the structure and function of biological membranes. The polymer backbone imparts a deep blue color to the materials which changes to red in response to the specific binding of biological targets such as viruses. These materials could be used as simple home or office sensing devices to diagnose various diseases.

Charych received her Ph.D. in Chemistry from UC Berkeley in 1992. She received a Division of Materials Sciences Award from DOE in 1993 for her research. She also supervises the research of MSD post-docs.

LBL lecture series: AT&T Bell Labs former head John Mayo to speak

John Mayo, recently retired president of AT&T Bell Laboratories, will be the next speaker in the LBL lecture series Science and Technology in a Competitive World. He will speak on "The Evolution of Information Infrastructures: The Competitive Search for Solutions" at noon on Wednesday, March 15, in the Bldg. 50 Auditorium.

Mayo earned his bachelor's, master's, and doctorate degrees in electrical engineering at North Carolina State University. He began his career with AT&T Bell Labs in 1955, where he served in a series of technical and management positions. He served as president from 1991 until his retirement in February 1995.

Mayo is a Fellow of the Institute of Electrical and Electronics Engineers and a member of the U.S. National Academy of Engineers. He has served as a director of Sandia Corp. and Johnson & Johnson. He is the recipient of many prizes and awards, including the NEC Computers and Communication Prize in 1988 and the U.S. National Medal of Technology in 1990.

Call for UCRS Board candidates

Employees who are active members of the University of California Retirement Plan (UCRP) but are not members of the Academic Senate are invited to run for election to the UC Retirement System (UCRS) Board. Candidates may be from any UC location except Lawrence Livermore; incumbent representative Patricia Erickson is from LLNL, and the two non-Academic Senate reps must be from different locations.

The non-Academic Senate members of UCRP will vote in June 1995 to fill one vacancy on the UCRS Board. Interested candidates must submit a petition signed by at least 50 active UCRP members who are not Academic Senate members, and a brief biographical statement. Nomination packets are available from the LBL Benefits Office (Bldg. 938), or the Reception Center (Bldg. 65).

UC Benefits must receive nominations by Friday, March 31.

The nine-member Board serves in an advisory capacity to the President of the University on matters concerning the UCRS plans. These plans are the UC Retirement Plan, the Defined Contribution Plan, and the Tax-Deferred 403(b) Plan. These plans hold assets of more than $19 billion and represent the retirement interests of approximately 157,000 UCRS members.

The UCRS Board generally meets quarterly in Oakland at the Office of the President. Members serve without compensation but are reimbursed for necessary expenses.

Laboratory welcomes new employees

LBL welcomed the following new employees to the Laboratory in February:

Computing Services debuts virtual store

The Software Store is back--this time on-line. Macintosh and PC users can get quick delivery of popular software titles at the Lab from the Macintosh and PC Support Group (MPSG) World Wide Web home page. Electronic order forms and a list of current inventory are located at

The on-line store is an attempt by Computing Services to improve software distribution at the Lab while keeping costs low. The department is also looking into network distribution, right-to-copy, and site licensing for LBL.

Users may also request the software from the new store by electronic mail ([email protected]) or through the MPSG Hotline at X6858.

Appletalk Remote Access

LBL and the UC Office of the President have completed an agreement with Apple Computer to add Appletalk Remote Access (ARA) software to the current site license.

ARA allows Macintosh users to access Appletalk services--including servers, printers, networked databases, and shared files--while at home or travelling.

UCOP anticipates that paperwork for the ARA addition will be completed in about a month. Shortly after, the Lab will receive the latest version of ARA, which will be installed on the WKSG server.



ALSNews, the weekly electronic newsletter for Advanced Light Source users, reports that in its two weeks of operation since the shutdown at the start of the year, the ALS has achieved a near-perfect performance record. During this time period, the ALS operated for 97.1 percent of its scheduled hours overall and 98.2 percent of its scheduled user-shift hours. ALSNews appears on the World Wide Web and can be subscribed to by sending an Internet address to [email protected]


The March 5 New York Times reported that scientists at Los Alamos National Laboratory have raised the possibility of buried nuclear wastes exploding at the proposed repository beneath Nevada's Yucca Mountain. The specter of a nuclear explosion prompted DOE to announce that it may seek an independent review of the Yucca Mountain program, which calls for the depositing of some 77,000 tons of high-level nuclear waste in a repository under the mountain, which is about 100 miles northwest of Las Vegas. The possibility that buried nuclear wastes might detonate was first raised last year by LANL physicists. Three LLNL teams were charged with investigating the idea and, if possible, disproving it. Though the theory was found to have many question marks and is thought by many experts to be unlikely, the teams were unable to completely disprove it. Researchers in LBL's Earth Sciences Division are involved in a number of studies related to determining the suitability of the Yucca Mountain site as a geologic repository of nuclear waste.


Science magazine reported last week that a group of scientists from Northwestern University have created a new composite material that may include the harder-than-diamond carbon nitride crystal predicted by LBL physicist Marvin Cohen and his then graduate student Amy Liu. In 1989, Cohen and Liu created a model with which they calculated that the short covalent bonds of a hypothetical crystal compound of carbon and nitrogen would make it harder than diamond. Since then, researchers trying to make thin films of carbon nitride with this predicted structure have generally produced an amorphous form of the material with no predictable structure at all. The Northwestern researchers are not sure yet whether they have actually created the material predicted by Cohen and Liu (they are now conducting tests to find out), but believe they already have a valuable new coating that is as hard as boron nitride, diamond's nearest rival, and much easier to make.


The same issue of Science also reported that DOE has decided to remove the National Academy of Sciences as co-administrator of the Radiation Effects Research Foundation. This foundation, which is funded jointly by the U.S. and Japan, has been conducting long-term studies of atomic-bomb survivors to better understand the health effects of radiation. Columbia University is expected to take over the U.S. portion of the Foundation's management. DOE said it was making the change because of the need to reduce NAS's high overhead costs, and the need to "expand the scientific capability" of the foundation.

Computing Zone: The ins and outs of e-mail

By Mike Wooldridge, [email protected]

If the measure of a hi-tech product's success is the amount of training needed to use it, electronic mail does quite well. Today's mail systems with graphical user interfaces allow even computer novices to send and receive messages, usually with a few mouse clicks.

But behind the user friendliness lies a great deal of complexity. LBL's e-mail network in some ways resembles an electronic Tower of Babel, with a variety of computer systems paired with several types of e-mail software, each with its own way of communicating.

E-mail traffic at the Lab averages about 50,000 messages a day, says ICSD's William Jaquith, LBL's Electronic Postmaster. The mail comes primarily from four systems: QuickMail for Mac users, cc:Mail for PC users, and separate mail systems for UNIX and VMS users.

The systems represent different generations of e-mail. UNIX and VMS have been sending and receiving mail since the mid-1970s, when the Lab was one of a few dozen sites on the Internet and e-mail was mainly used by computer scientists.

The newcomers are QuickMail and cc:Mail, window-based products that have been widely used only in the past five years. "It's the graphical interfaces in systems like QuickMail and cc:Mail that have really brought electronic mail to everyone," Jaquith says.

Speaking the same language

Sending messages within a single e-mail system is relatively straightforward. Like spokes on a wheel, users on a given system are linked via central mail servers that route messages between users quickly and directly. It's when sending mail from one system to another that things get complicated.

The main way the Lab keeps the communication channels open is with a common language, or more precisely, a standard set of mail protocols that different systems can understand. At LBL, as at most large institutions, the common ground is SMTP (Simple Mail Transfer Protocol).

SMTP was developed 25 years ago for mail transfer over the Internet, where it is still used. "The Internet's success has made SMTP the logical electronic mail `backbone' for institutions with different systems," says Bob Fink of ICSD's Communications and Networking Department.

This makes communication in some ways easier for the UNIX systems at the Lab, since they use SMTP to begin with. QuickMail, cc:Mail, and VMS, however, have their own separate mail protocols, and must translate their messages to SMTP to communicate with other mail platforms.


The translators are known as gateways. The Lab's QuickMail system, for instance, has six "macmail" gateways that transfer QuickMail messages between it and other platforms. VMS and cc:Mail have similar gateways.

Gateways work in a "store and forward" fashion, transmitting e-mail messages in cycles. This allows message transfer to be flexible. If a piece of mail cannot be delivered--because the destination computer is down, for example--it can be held at the gateway and retried later. Typically, if a message can't be delivered after three days, it is returned to the sender along with an explanation.

The central link between electronic mail at LBL and the outside world is a gateway known as "" which handles Lab e-mail to and from the Internet. Messages can travel via to addresses at any of the thousands of other Internet sites worldwide--educational institutions such as UC Berkeley (, research institutions such as CERN (, and commercial sites such as Apple Computer (

Electronic Post Office

Gateways know where to direct e-mail on-site because of a registry known as the LBL Electronic Post Office. Each user registered at the EPO has an alias consisting of a first and middle initial, and last name. The alias is indexed with the e-mail address specific to a particular system where the user prefers to receive mail. Jaquith, for instance, has the alias "WDJaquith" linked to the address on his VMS account ([email protected]).

The EPO simplifies e-mail transfer on the Hill by rerouting mail when an employee's e-mail address changes. Instead of notifying correspondents of a new address, users can simply change their entry in the EPO.

The EPO also serves as a resource standard. QuickMail and cc:Mail look up e-mail addresses using the information at the EPO. EPO addresses are also listed in the LBL phone book and in the x.500 electronic staff database.

Handling enclosures

Thanks to the network of gateways and servers, LBL e-mail generally flows without a hitch, with one exception--enclosures. Enclosures are non-text or "binary" files, such as graphics, spreadsheets, and formatted documents, that users can attach to their e-mail messages.

As with regular message transfer, the variety of computer systems on the Hill is what makes enclosures a challenge. "It is similar to the problems you have moving a file on a floppy disk from a Mac to a PC," says Mark Rosenberg of ICSD's Central Microcomputer Support group. "You are always going to be stuck with some incompatibilities."

QuickMail and cc:Mail can send enclosures to one another quite reliably. ICSD has configured cc:Mail and QuickMail gateways so that enclosures are encoded in the same "language," a format known as AppleSingle-UUENCODE.

However, the sticking point often comes not because of the e-mail system, but because of the software used. Enclosed files are useless if a person doesn't have an application that can read or translate them.

Making enclosure transfer flawless on-site may only be possible with a single e-mail system that can work on the variety of computers on the Hill. Such a system would make the e-mail network considerably less complicated, since it would need just a single translating gateway.

LBL may eventually find such a solution with groupware. Popular in private industry, groupware systems are integrated software packages with electronic mail, scheduling programs and other components that users can share over a network. Lotus Notes and Novell GroupWise are examples of groupware packages. The LBL Electronic Workplace Process Improvement Team is currently exploring how the Lab can implement groupware on-site.

Terms to know

Mail Call

For you to receive all the e-mail that is addressed to you, the computer network at the Lab has to know where to send it. The LBL Electronic Post Office, a registry of employees and their e-mail addresses, helps e-mail systems route messages correctly. William Jaquith, LBL's "Electronic Postmaster," estimates that as many as one-fifth of the Lab's computer users may not be registered. If you think you may not be on the list, contact the Electronic Postmaster ([email protected]).

Lab to offer night escort service

For LBL personnel who need to work late at night and do not have a vehicle on site, the Laboratory has arranged for a limited night escort service with the UC Berkeley Police Department.

The service, which will operate on a three-month trial basis beginning Monday, March 13, will be available seven days a week between the hours of 6 p.m. and 2 a.m.

To arrange for an escort, go to the Blackberry Canyon Gate (main gate) and ask the person on duty to call for an escort. The escort will pick you up at the gate and take you to nearby public transit or a campus shuttle stop.

Because the service will be operated on a trial basis, your comments about the service are welcome. Please address them to Ruth Pepe at Site Access Services, X6198, [email protected], or M.S. 65.

Berkeley chamber casino night

LBL employees are once again invited to the annual Speakeasy Casino Night sponsored by the Berkeley Chamber of Commerce. The fundraiser takes place from 7 to 10:30 p.m. on Friday, March 31, at the Berkeley Yacht Club, Berkeley Marina.

In addition to games, a hors-d'oeuvre buffet will be provided. Fedoras, feathers, and other festive accoutrement are encouraged. Prizes include a Reno trip, bed-and-breakfast weekends, lunches, and gift certificates to various local establishments.

Tickets cost $25 (which provides $25 in betting chips). They can be purchased from Shaun Fennessey in Community Relations (X5122).

Lab commended by work-family coalition

One Small Step, a work-and-family coalition of major Bay Area employers, has commended LBL for its achievement in assisting employees with managing work and family responsibilities. This is the second year that the Lab has been recognized by the coalition.

Human Resources' Michael Goldstein, LBL's representative on the coalition, presented Janet Jacobsen and Marva Wilkins with the certificate of recognition. Jacobsen, a researcher in the Earth Sciences Division, received the award on behalf of the Work/Family Committee, which was recognized for providing "a forum for employees to identify and discuss work-related problems that they face due to dependent-care responsibilities."

Wilkins and the organizers of LBL's Take Our Daughters to Work Day were recognized for introducing daughters to a variety of professional career options and reinforcing a feeling of community at LBL. The recipients were announced at One Small Step's sixth annual membership conference on February 1.

Health Notes

Achoo ... Allergy season is here

The good news is the drought is over. The bad news is that this means high pollen counts, which is a problem for allergy sufferers.

Some of the common symptoms of allergies are: sneezing; watery, itchy eyes; stuffed-up nose; runny, itchy nose; fatigue; irritability; and trouble concentrating.

Suggestions for coping include:

There are two basic types of over-the-counter allergy medications: antihistamines and decongestants.

Use an antihistamine if you have sneezing; itchy, runny nose; itchy, watery eyes; itchy throat and skin.

Use a decongestant if you have stuffy, clogged-up nose, ears, head.

Antihistamines give temporary relief by blocking the action of the allergens. To get best results, take before the symptoms appear. Antihistamines rarely cause serious side effects, but do cause drowsiness, dry mouth, and upset stomach. The drowsiness usually goes away in a few days as your body adjusts. Other drugs, i.e., alcohol and/or tranquilizers, can intensify the drowsiness.

Check with your physician before taking this medicine if you are pregnant, breast feeding, have glaucoma or difficulty urinating due to an enlarged prostate gland. Some asthmatics may have problems with antihistamines.

Decongestants relieve stuffiness of the nose, ears, and head by shrinking the mucus membranes. They may be taken alone or with antihistamines. Unlike antihistamines, they may be taken after symptoms appear. Decongestants can make you jittery, nervous, or restless. This, too, will improve as your body adjusts to the medication. You may want to take decongestants only during the day.

Again, check with your physician if you are pregnant, breast feeding, have high blood pressure, diabetes, glaucoma, or heart problems.
