Li Zhijian, electronics specialist, professor of microelectronics, Fellow of the Chinese Academy of Sciences, chairman of Academic Committee of the Information Science And Technology School, Tsinghua University.

    He was born on 1st May, 1928 in Ningbo, Zhejiang province. He obtained his bachelor's degree in physics from Zhejiang University in 1951 and was awarded a Science Doctorand by National University of Leningrad, Russia. He has held the position of Director of the Institute of Microelectronics, Tsinghua University for years. He holds the following honorable positions in academic societies: Vice President, Chinese Institute of Electronics; Vice Chairman, Chinese semiconductor and Integrated Circuits Technology Association; Member of the Editorial Commission of "Chinese Journal of Electronics "and "Chinese Journal of Semiconductors ". He has served as the Meeting President, member of International Advisory Commission and/or Program Commission of Several International Conferences, such as: ICSICT (93, 95) (International Conference on Solid State Device and Integrated Circuit Technology), SSDM (95, 96, 97, 98) (Solid State Material and Device Meeting, TECON (96) (IEEE Region 10 Conference), etc..

    Professor Li Started semiconductor research since 1953. He had successfully proposed an intercrystalline electron harrier model to explain the photo conduction behaviors of the thin semiconductor films. In the earlier part of his career he had contributed greatly to the development of silicon-based device technology in China: firstly developed the utra-pure silicon material (1960), fabricated silicon alloy transistor (1962) and high voltage planar silicon transistors (1965). Due to his in depth investigation of Si/SiO2 interface and MOS physics, he had won a National Education Commission Prize for Science and Technology Progress. Professor Li began his researches on ICs (Integrated Circuits) since 1965. In 80's, his group succeeded in development of a series of LSI (Large Scale Integration) and VLSI (Very Large Scale Integration) IC chips, such as: 2Kbit EEPROM, 16Kbit high speed SRAM, 16bit CPU, etc. His project "3 Micron LSI Process Technology And Relevant ICs Development" had received a National Award of Science and Technology Advancement in 1987 (2nd Rank). His another project "1-1.5 Micron VLSI CMOS Technology and 1 megabit Chinese Character Storage ROM" had received the same Award in 1995. Professor Li and his coworkers' invention "VLSI Rapid Heat Processing Technique And System" has been patented in China and United State of America, and won him the 1990 National Inventions Award (2nd Rank).

    Since 1990, professor Li's research interest is focused on the "System-on-chip" integration technology. His works on "CMOS Current Mode Fuzzy Logic Microprocessor", "VLSI Implementation of System Chips for Hand Written Character Recognition and Voice Recognition Based on Artificial Neuron Networks and Fuzzy Logic", etc., have archived some sounding results. Taking as the intelligent systems' input and output parts, professor Li actively works on the development of silicon based MEMS (Micro Electro Mechanical Systems) technology. A series of MEMS devices, namely micro motor, micro pump and micromicrophone have been successfully developed in his laboratory. Professor Li keeps more than five patents of United State of America in this field.

   Professor Li was awarded "1997 Tan Kahkee Prize for Information Science" and "2000 Ho-Leung-Ho-Lee Foundation Science and Technology Progrsss Prize". The following figure is that the President of Singapore(second one form right) congratulated professor Li at the ceremony.
