先进工业国家在电子新材料的研究及应用方面发展很快,竞争激烈.日本1984年提出了电子材料综合开发计划;美国提出协同研究体制,特别是在宇宙空间制造完美晶体的计划尤为引人注目.一、硅材料和半导体化合材料硅单晶是制造半导体器件的基础材料,用二氧化硅制成的石英光纤广泛用于光通信领域.当前硅的制造技术 Advanced industrial countries have witnessed rapid development and fierce competition in the research and application of electronic new materials. Japan put forward the plan for the comprehensive development of electronic materials in 1984; and the United States put forward a synergistic research system, especially the plan for creating the perfect crystal in the cosmic space First, the silicon materials and semiconductor compounds Silicon single crystal is the basis for the manufacture of semiconductor devices, made of silica quartz fiber is widely used in optical communications. The current silicon manufacturing technology
