GIBBS-LIPPMANN EQUATION UNDER STM EXAMINATION
J. Janata
In tunneling microscopy the tip, the gap and the conducting substrate form a capacitor. Similarly, in electrochemistry of polarized electrode the metal and the electrolyte form a double layer capacitor. It is shown that the energetics of these two capacitors, namely the surface tension of the STM substrate and of the polarized electrode, respectively, are governed by the same relationship, the Gibbs-Lippmann equation. The implications of this finding for STM imaging are discussed.

The speaker: Jirí (Art) Janata received his PhD in analytical chemistry from the Charles University, Prague, in 1965. After postdoctoral studies at the University of Michigan he spent six years in the Corporate Laboratory of ICI in England and in 1976 joined the faculty of the University of Utah in Bioengineering and Materials Science. Since 1992 he was an Associate Director of Environmental Molecular Sciences Laboratory at the Pacific Northwest Laboratory. In 1997 he became an Eminent Scholar of the Georgia Research Alliance in the School of Chemistry and Biochemistry at the Georgia Institute of Technology. His interests include chemical sensors, electrochemistry, interphasial physical chemistry and microfabrication.

A poster session with cocktail hour and dinner followed the invited talks. Twelve posters were presented on various aspects of electrochemical science. This meeting format was very successful and enjoyable for all those who attended and the local section is planning to hold annual topical symposia.

April 11th, 1996
National Speaker - Barry Miller
"New Electrochemistry for Carbon-Diamond and Fullerenes"
The electrochemistry of fullerenes on graphite electrodes are particularly rich, showing an optical sensitivity and multiple levels of reduction at cathodic bias. He described the unique properties of thin p-type diamond films deposited on silicon wafers. These electrodes are very stable over a wide range of potential, even at high anodic bias. The high over potentials are thought to be due to the limited number of available states in the diamond and a collection of localized acceptor surface states. Professor Miller also presented an overview of the healthy status of the Society.
 

August 8th, 1996
"New Materials and Transducers for Chemical Sensors" by Wolfgang Göpel, University of Tubingen, Germany
Dr. Göpel will survey "top-down" (microstructure) and "bottom-up" (chemical synthesis) approaches to designing chemical and biochemical sensors. Emphasis is on new materials and transducers for molecular recognition with current and future devices. "Lock- and-key" structures convert chemical information into electrical signals. This requires control of atomic structures of chemically sensitive materials under equilibrium or kinetic control. Recognition and transduction mechanisms are deduced from microscopic, spectroscopic, and sensor-response studies on prototype devices. Selected examples illustrate this approach for different materials, including electron conductors, mixed conductors, molecular cages, polymers, and biomolecular functional units. He will also discuss the ultimate limits of miniaturization of sensors, and the development of "electronic noses" for chemical sensing.

October 24th, 1996
"Temperature-Dependent Studies in Electrochemical Surface Science" by Gregory Jerkiewicz, University of Sherbrooke, Department of Chemistry.
Temperature variation can affect numerous electrochemical surface processes such as the under-potential deposition of hydrogen and metals (UPD-H and UPD-M, respectively), surface oxide formation and reduction, or anion adsorption. In the case of surface oxide formation on noble metals, the temperature increase augments the rate of surface oxidation, thus the oxide thickness. In the case of UPD-H and UPD-M, temperature dependence studies followed by theoretical treatment lead to determination of thermodynamic state functions such as Gibbs energy change of adsorption, entropy change of adsorption and change in adsorption enthalpy. Knowledge of the enthalpy change of adsorption is essential in subsequent elucidation of the bond energy between the metal substrate and the UPD species, thus in evaluation of the surface cohesive forces that are responsible for the adhesion of the adsorbate to the substrate. Dr. Jerkiewicz presented experimental data which lead to determination of the bond energy between UPD evolved hydrogen and noble metal substrates. Subsequently, he demonstrated how coadsorbed S adatoms influence this bond energy through local electronic effects. Finally, he showed data on H and sulfate adsorption on Pt(100) and Pt(111) electrodes.
There were 12 dinner guests and 3 more joined for the after-dinner talk.

December 5th, 1996
"Using EC-SPM To Induce and Monitor Processes at the Liquid-Solid Interface" by Daphna Yaniv, Molecular Imaging, 1200 East Broadway, Tempe AZ 85282.
Combining electrochemistry with scanning probe microscopy (SPM) enables inducing surface processes at the liquid-solid interface and simultaneously imaging them. By using in-situ electrochemical SPM (both Scanning Tunneling and Atomic Force Microscopy), surface images with resolution ranging from atomic/molecular to tens of square micrometers can be obtained. Numerous examples were shown to demonstrate variety of EC-PSM experiments, such as surface reconstruction, potential induced surface dissolution, order-disorder transitions, molecular recognition, corrosion processes, tip-induced deposition, and tip-induced etching. She also presented the consideration behind the design of an SPM for electrochemical imaging, focusing on environmental and temperature control imaging.
After the talk we were able to take a close look at the actual probe, its attachments, Peltier cooling stage and insulated tips.
There were 14 dinner guests at this meeting in spite of snow and sleet on the roads earlier that day.

Meeting held at the University of Illinois at Chicago

March 3rd, 1997
"Silicon Processing and Thin Film Integrated Electronics" by Robert H. Reuss, Motorola Automotive, Energy and Components Sector
Abstract: The talk will focus on the evolution of silicon processing with emphasis on application to display technology, particularly active matrix LCDs. Trends in substrate sizes, devices/cm2 etc. will be reviewed and discussed in the context of the growth of microelectronics (for memory and logic) and "giant electronics" (for displays and related products). These trends will be compared and contrasted and projections of where these related, but different technologies will be applied for emerging markets such as integrated electronics will be suggested. Areas of active research in this dynamic field as well as requirements for realization of thin film integrated electronics will be highlighted.
Dr. Reuss received his Ph.D. in Chemistry from Drexel University in 1971. He has been a member of the Research Faculty of the University of Colorado, worked for the government as a research and development manager for seven years, and joined the Motorola Semiconductor Product Sector in 1981.

National Speaker
Murray Bullis, "Semiconductor Equipment and Materials International: 300 mm Silicon for ULSI Circuits"

Abstract: The transition from 200 mm to 300 mm silicon wafers is expected to be extremely costly, but inevitable. Costs will be minimized if wafers, equipment interfaces, etc., are standardized worldwide. Technologists in the US, Europe, Japan, and the Pacific Rim have been developing specifications for 300 mm wafers for over a year. The larger wafers will differ in several significant ways. We will review the dimensional and crystallographic attributes of 300 mm wafers compared to smaller ones. We will consider physical properties appropriate to 0.25 and 0.18 micrometer design rules, based on the National Technology Roadmap for Semiconductors. Finally, we will consider briefly the state of metrology needed to support these requirements.

W. Murray Bullis joined Semiconductor Equipment and Materials International as Director of Standards in January 1996. He had previously been with Siltec Silicon, the Fairchild Research Center, the National Bureau of Standards, Texas Instruments, Farnsworth Electronics, Los Alamos National Laboratory, and Lincoln Laboratory. He earned his Ph.D. at MIT in 1956 and his A.B. at Miami University (Ohio) in 1951. He has published over 50 papers and five book chapters in silicon technology.

The meeting had 12 attendees for the social, dinner and the talk. During the social a lively discussion ensued with our guest regarding various issues concerning the state of the Society. Prior to the technical talk we have received a thorough report about the health of the Society. We are duly noting the need of timely filing of financial statements, due in early January. It was also pointed out that the Society is able to take care of the section funds, as opposed to keeping them in a local bank. The advantage would be earning interest and saving on the bank maintenance fee; the downside might be inability to write checks. The issue should be further discussed during the planning meeting, which will be held in July.

September 18th, 1997
Rhonda Franklin Drayton, University of Illinois at Chicago: High Frequency Circuits based on MEMS Techniques

Abstract: Planar circuits and antennas in high frequency applications are prime candidates for improved performance and miniaturization using Silicon micromachining. Many circuits and antennas designs of this type suffer from parasitic effects that ultimately alter the desired performance as a result of inherent mechanisms found in planar technology. This presentation will highlight the issues affecting performance in high frequency circuits and antenna and will present examples that illustrate the role that Silicon micromachining has served in providing significant performance improvements. Additionally, important fabrication challenges will be described for planar circuit designs with discussion on the role that micromachining has played in resolving some of these issues. Finally, new concepts in circuit design will also be presented that offer enhanced design flexibility to traditional design techniques. These structures are produced using micromachining to realize three-dimensional structures that perform important circuit functions, such as filtering.

Rhonda Franklin Drayton joined the faculty in the EECS Department at the University of Illinois at Chicago in January 1996. She has also worked as a research engineer at Lawrence Livermore National Laboratory. Her interests are in high frequency circuits and antennas, advanced packaging, optoelectronic circuits, and MEMS processing techniques. She earned both M.S. and Ph.D. in electrical engineering at the University of Michigan in 1990 and 1995, respectively, and the B.S.E.E. at Texas A&M University in 1988. She has published over fifteen papers in referred journals and conference proceedings, co-authored a book chapter in advanced packaging using micromachining techniques, and received a US. patent on micromachined self-packages.

National Speaker
Vitali Parkhutik, Technical University of Valencia, Spain: "Porous Semiconductors - What We Know and What Remains Mystery about Them"

Abstract: Porous silicon has attracted much research during last seven years due to expectations of its implementation in light-emitting devices. However, the progress was rather poor and many important issues in the formation of porous silicon films and their properties were left unsolved. The talk will be focused on the problems of physics and chemistry of porous semiconductors which remain unsolved and thus should be addressed by future researchers to ensure the practical applications of porous semiconductor materials. Special emphasis will be made on the results of the author in studying the mechanism of growth of porous semiconductors.

Speaker: Prof. Vitali Parkhutik received his Ph.D. from Bielorussian State University (Minsk, Biela Russia) in 1979. The thesis and much of further work was concentrated on studies of oxidation of metals and semiconductors in a low-temperature oxygen plasma and electrolytes. His post-doctoral research activities were related with the Minsk Radioengineering Institute (Bielorussia) where he occupied positions of senior and then leading researcher of the Microelectronics Department during 1979-1992. Since 1992 he moved to Spain to work on porous silicon growth and characterization, first at the Madrid Autonomous University and further at the Technical University of Valencia where he actually occupies a tenure-track position of full professor. Actual research activities of Vitali are shared between porous semiconductors and conjugated polymers.

New Interfacial Materials for Array-Based Chemical Sensors.
 

Wednesday, January 14, 1998
Dr. Changming Li, Motorola: "Biosensors"

Abstract: A biosensor may be broadly defined as any measuring device incorporating a biological element either intimately connected to or integrated within a transducer. Generally, a biosensor is to produce an electronic signal which is proportional to the concentration of a specific chemical or set of chemicals. The marriage of two contrasting disciplines combines the high specificity and sensitivity of biological systems with the power of modern electronic technologies including advanced computer applications. This emerging technology crosses many traditional academic delineations and provides powerful tools for analytical science and industry. Various biosensors will be briefly presented. A novel glucose oxidase sensor will be discussed in detail. In the past decade there have been very significant developments in the amperometric glucose sensor. Usually, the glucose sensor is fabricated by immobilizing the enzyme bounded redox mediator to the solid electrode surface. The modification of the inner surfaces of porous carbon microelectrodes was studied and the electrode with such a structure was used to make the amperometric glucose sensor. Due to the unique modified electrode structure, the sensor significantly improves the measurement sensitivity.

Speaker: Dr. Changming Li received his B.S. in polymer chemistry from Chinese University of Science and Technology and Ph.D. in physical chemistry from Wuhan University in PRC in 1986. In 1986, He became the assistant professor in Wuhan University. He has worked in University of Illinois at Champaign-Urbana, and in World Precision Instrument Inc. at Sarasota. He has joined Motorola as the senior staff engineer since 1994. He is the honored Member in NIH Multidisciplinary Study Section. Dr. Li's R&D interests include electrochemistry and material science, particularly in batteries and sensors. He has 44 publications and holds 15 U.S. patents.
