RESEARCH EXPERIENCE

WANG Xi is dedicated to the research of energetic ion beam and physical phenomena of solid interaction, and their application in high-end integrated circuit substrate material Silicon-on-Insulator (SOI). He established Chinas only SOI R&D and manufacture base Shanghai Simgui Technology Co., Ltd. to meet the national demand in space electronic devices. He and his team overcame the ultra-low dose oxygen ion implantation and ultra-high temperature precision control annealing technology gap, developed the low-cost high-quality Super Low Dose (SLD) SOI technology, and created the unique Simbond SOI with core independent property right in the world, which industrialized the 8-inch SOI materials and was exported to the developed countries. In addition, the SOI products also contributed to the independence of core components in special area. As a member of Shanghai Advisory Committee for Policy Decision, deputy chief engineer of National Science and Technology Major Project 02 special project, he has promoted a number of major semiconductor projects in Shanghai, among which the 12-inch integrated circuit silicon wafer is expected to fill the national gap in this field. Shanghai Industrial μTechnology Research Institute (SITRI) has become the beams and pillars of Technological Innovation Center in Shanghai. IMEC China Institute will provide a solid platform for attracting the world class R&D center, and MRAM project will lay the foundation for competing for the global new generation memory chip.
