Prof. Steve S. Chung from the National Chiao Tung University of Taiwan (NCTU) visited the Institute of Microelectronics of Chinese Academy of Sciences (IMECAS). With ProfLIU Ming's arrangement On September 5th 2013. He delivered a lecture entitled “The Charge Loss Issues in a Two-bit SONOS Flash Memory- Low Voltage Operating Schemes and Solutions” in IMECAS hosted by Prof. LIU Ming, the director of Lab of Nanofabrication and Novel Device Integration Technology. More than 30 local professionals and graduate students attended the meeting.  

Prof. Steve introduced several designs for SONOS-type flash memories which can provide good reliability, high-speed and low voltage operation. It is also claimed that a wrapped gate SONOS may enable better performance for 2-bit per cell operations to achieve excellent data retention. Prof. Steve also explained that the mismatch between electrons and holes could be solved with a good combination of programming/erasing schemes. The new points of his research on SONOS flash memory devices made a big splash and reached an academic discussion. 

After the lecture, a symposium was held with the participating researchers from the Laboratory of Nanofabrication and Novel Device Integration Technology of IMECAS, both sides introduced their recent works and had an heated discussion.

Bio of Steve S.CHUNG:

STEVE S. CHUNG received his Ph.D. degree from the University of Illinois at Urbana-Champaign, in Electrical Engineering in 1985. His Ph.D. thesis advisor is the world-famous scholar and CMOS Co-Inventor, Prof. C. T. Sah. He joined National Chiao Tung University (NCTU) in 1987 and currently, a Chair Professor and UMC Research Chair Professor at NCTU. In 2007-2008, he has been the Dean of International Affairs at NCTU. Between 2004-2005, he was the first Department Head of EECS Honors Program, to promote an undergraduate program for academic excellence. He has also been a Research visiting scholar with Stanford University in 2001 and a visiting professor to University of California, Merced, 2009-2010. He was also the consultant to the two world largest IC foundries, TSMC and UMC, on developing CMOS and flash memory technologies. His current research areas include CMOS devices; flash memory, and reliability characterization; and nano-science in bio applications. He has published more than 180 journal and conference papers, one textbook, and holds 20 patents. From 1995-2008, he presented around 20 times in the prestigious IEEE conferences, IEDM and VLSI. 

He is an IEEE Fellow, AdCom member, Distinguished Lecturer, Regions/Chapters Vice-Chair of EDS, and Editor of EDL. He has served on the committees of premiere conferences, e.g., VLSI Technology, IEDM, IRPS, etc. ED Taipei chapter was awarded the 2002 EDS Chapter of the Year Award under his leadership as the chapter chair. He was awarded 3 times outstanding Research Award for excellence in research, and a distinguished research fellow of National Science Council since 2006. He was also granted Distinguished EE Professor and Engineering Professor by the Engineering Societies of Taiwan.
