October, 2005 EMRL/FMRL ESSENCE AND METHODOLOGY OF MATERIALS SCIENCE YAO XI ELECTRONIC MATERIALS RESEARCH LABORATORY XIAN JIAOTONG UNIVERSITY, XIAN, 710049, CHINA FUNCTIONAL MATERIALS RESEARCH LABORATORY TONGJI UNIVERSITY, SHANGHAI, 200092, CHINA XIAN – SHANGHAI ELECTRONIC MATERIALS RESEARCH LABORATORY FUNCTIONAL MATERIALS RESEARCH LABORATORY ULTRA RAPID DEVELOPMENT OF MORDERN SCIENCE AND TECHNOLOGY ELECTRONICS Development of Computer Technology; Working Frequency of CPU; RAM Capacity; Hard Disk Drive Capacity. Development of Optical Communication and Mobile Communication Technology; Development of Internet Technology. DRIVING FORCE OF THE RAPID DEVELOPMENT External：Striving for better and easy life from Human Being； Internal: Optimum Interaction and Positive Feed Back among: System – Device -- Material Electronic System – Integrated Circuit -- Silicon Electronics – Microelectronics – Solid State Electronics BOTTLE NECK OF THE FUTURE DEVELOPMENT OF ELECTRONICS MATERIALS Microelectronics High K Dielectrics Low K Dielectrics Optoelectronics What is the “Silicon” of Optoelectronics? MEMS Sensing and Actuating Materials; Can silicon alone be a good Micro Electro-Mechanical System? FOUNDATION AND PIONEER OF MODERN SCIENCE AND TECHNOLOGY MATERIALS SCIENCE AND TECHNOLOGY No silicon and silicon technology, No microelectronics and electronics today! No silica fiber and fiber technology, No optical communication today! MATERIALS AND SOCIETY Materials and Energy were the backbone of Human Society; Materials, Energy and Information are the three major pillars of Modern Society. EARLY STAGE AND EVOLUTION OF MATERIALS SCIENCE The launch of Soviet Satellite ?? the Sputnike; The Establishment of Materials Research Centers in United State under the Act of US Congress; The Organization of Materials Research Society; The Journal of Materials Science; The Annual Meeting of Materials Symposium; The International Materials Research Society: EMRS, CMRS, MRS?J, MRS?K, MRS?T, MRS?I
