by Hosler, Daniel A 19 Jul '12

19 Jul '12

I am happy to announce the new Rapid Thermal Annealer (RTA) is open for training. This new RTA resides in R-Bay of the cleanroom, and has many improved capabilities over the old RTA systems. It has 4 process gases, atmospheric or vacuum capability, thermocouple or pyrometer temperature control, and also a maximum temperature of 1200°C (for a very short period of time). Please e-mail me at dhosler(a)purdue.edu for training or for more information. If you would like training, I will send you the Standard Operating Procedure for review, and we will also discuss your process requirements. Thank you, Dan Hosler 496-3883

Special Joint Condensed Matter Physics and BIRCK Nanotechnology Center Seminar Friday, March 30, 2012 Refreshments 3:15 PM/Seminar 3:30 PM 4:30pm - 5:00pm faculty interaction reception BRK Atrium BRK, ROOM 1001 Chih-Kang Shih Jane & Roland Blumberg Professor of Physics Department of Physics University of Texas, Austin Ultra-thin epitaxial metallic films on semiconductors - A playground for exploration of novel quantum phenomena at nanoscale When an electronic system is confined in one or more dimensions to a length scale comparable to the de Broglie length, quantum confinement occurs. Such confinements have played central role in artificially engineered electronic systems such as quantum wells, wires, dots and related structures. For semiconductors, quantum confinements occur at a length scale somewhere around 100 nm. For metals, however, they occur at a length scale about one to two orders of magnitude smaller (1-5 nm). Investigations of quantum size effects in ultra-thin metallic films have recently gained tremendous amount of interests. These renewed interests are largely driven by the advancement in atomic scale control in epitaxial growth of metallic thin films, thus making it possible to access this strongly confined regime. In this presentation, we describe several interesting phenomena resulting from the confinement of electronic waves in metallic nanostructures. These include: (a) quantum size effect on nanostructure formation, (b) quantum size effect on workfunction of nanostructures, (c) quantum size on effect on superconductivity.

Dr. Yoshi Yamada Seminar March 26 @ 11:00 AM - 12:00 PM - BRK 1001 Title: Non-contact temperature measurement for semiconductor device fabrication and evaluation Abstract: Optical methods of temperature measurement such as radiation thermometry and thermoreflectance are essential tools for thermal measurement in semiconductor device fabrication and evaluation due to such features as fast response and high special resolution. In this presentation, practical implementations of these techniques in industrial scenes are presented. The first is a silicon wafer surface temperature monitoring system by thermoreflectance during plasma etching. To overcome such difficulties as low sensitivity and limitation in installation space and position for in-situ measurements, differential thermoreflectance utilizing two orthogonal polarizations was introduced. The second is radiation thermometry of silicon wafer surface temperature during flash lamp annealing (FLA). A novel approach for emissivity compensated radiation thermometry was applied to sub-millisecond response measurement. Results of thermal profile measurements conducted on a FLA chamber are described. An extension of this emissivity compensation technique to infrared thermal imagers is presented, intended for monitoring of local heat generation in highly-integrated or high-power semiconductor devices. Short biography: Prime Senior Researcher at the National Metrology Institute of Japan, National Institute of Advanced Industrial Science and Technology (NMIJ, AIST). Received BS and MS degrees from the University of Tokyo in 1983 and 1985, respectively, in Instrumentation Physics, and MS degree from Caltech in 1992 in Electrical Engineering. Spent 13 years in NKK, working on in-situ optical measurement in steel production, prior to joining NMIJ, AIST. Current research activities include high-temperature standards, industrial non-contact temperature measurements, and calibration of earth observing space-borne hyperspectral sensors.

REMINDER: James C.M. Hwang Seminar TODAY at 10:00am in MRGN 121
by Sigo, Angie 22 Mar '12

22 Mar '12

Prof. James C.M. Hwang (hosted by Prof. Peroulis and Prof. Ye) Today, March 22 @ 10:00 AM - 11:30 AM - MRGN 121 Abstract: The Air Force Office of Scientific Research seeks scientific breakthroughs in solid-state materials and devices that are vital for game-changing capabilities in sub-millimeter-wave radar, ultra-wideband communications, chemical/biological/nuclear remote sensing, and ultra-high-speed on-board and front-end data processing. Such capabilities are crucial for long-term USAF C4ISR capability breakthroughs. Research proposals are sought that address high-risk, high-payoff topics having fundamental challenges that are scientifically interesting as well as technologically relevant. Currently, the research portfolio is organized in three thrusts: I) THz Electronics: These include materials and devices of covalent-bond semiconductors such as C, Si, Ge, GaAs, InP, GaN, and related compounds. The main challenges are in perfecting crystals, interfaces, transports and hetero-structures, as well as scaling to nanometer dimensions for THz operations, while maintaining adequate device characteristics such as on/off current ratio, sub-threshold turn-on slope, and breakdown voltage. Particular emphasis will be placed on approaches that can lead to high-power THz sources, such as MOSFETs or MISFETs with high-K gate stack on wide-bandgap semiconductors capable of high channel trans-conductance and low electron tunneling. II) Novel GHz Electronics: These include materials and devices of ionic-bond semiconductors such as complex oxides of transition metals, with less overlapped electron orbitals and much higher bandgaps that may relax the requirement on crystalline perfectness while delivering much higher power than covalent-bond semiconductors can. The main challenges are in understanding different mechanisms for higher-quality, larger-area, and lower-cost growth on flexible or conforming substrates, as well as in understanding doping mechanism, correlated transport, and metal-insulator transitions, especially in terms of high-concentration p-type doping and transport in oxide hetero-structures. Scaling to advance operation speed from the GHz range toward the THz range will also be explored. III) Reconfigurable Electronics: These include materials and devices of non-semiconductors that can perform multiple electronic, magnetic and optical functions. Devices based on meta-materials, artificial dielectrics, ferrites, multi-ferroics, nano-magnetics, and micro/nano electromechanical systems for reconfigurable radio-frequency front-ends will be of interest. The main challenges are in understanding the interaction between electromagnetic waves and electrons, plasmons and phonons on the nanometer scale. Additional challenges involve understanding of reproducible material preparation and approaches for devices that are compact, light, low-power-consumption, and low-cost. Bio: James C. M. Hwang is a Professor of Electrical Engineering and Director of the Compound- Semiconductor Technology Laboratory at Lehigh University. He graduated with a B.S. degree in Physics from National Taiwan University in 1970, and completed M.S. (1973) and Ph.D. (1976) studies in Materials Science at Cornell University. After twelve years of industrial experience at IBM, AT&T, GE, and GAIN, he joined Lehigh University in 1988. His current research interests include micro-electromechanical systems, radio-frequency transistors and integrated circuits, optoelectronics and bio-electromagnetics. He has been a Nanyang Professor at Nanyang Technological University in Singapore and an Advisory Professor at Shanghai Jiao Tong University, East China Normal University and University of Science and Technology of China. He co-founded GAIN and QED; the latter became a public company (IQE). He has published approximately 300 refereed technical papers and has been granted five U. S. patents. He became an IEEE Fellow in 1994. He received the CIE Outstanding Achievement Award and the IBM Faculty Award in 2007, as well as the WOCC Outstanding Contribution Award in 2011. Currently, he is on leave from Lehigh University to serve as a program manager of GHz-THz electronics at the US Air Force Office of Scientific Research. --------------------------------------- Angie Sigo Secretary, Skywalk Atrium Birck Nanotechnology Center 1205 W.
