北京有研总院研制成功我国第一根直径12英寸直拉硅单晶我国第一根直径12英寸(300mm)、等长度400mm、晶体重量81公斤的直拉硅单晶,已由北京有色金属研制总院半导体材料国家工程研究中心研制成功,从而使我国成为世界上少数几个具有此能力的国家之一。北京有色金属研究总院半导体材料国家工程研究中心,是我国半导体材料研究开发的主要基地,分别于1992年、1995年相继拉制成功国内第一根直径6英寸、8英寸的直拉硅单晶,并于1995年建成了我国第一条直径6英寸硅抛光片生产线。产品销往国内外,取得了显著的经济效益和
Beijing Institute of Research has successfully developed China’s first 12-inch diameter Czochralski crystal China’s first diameter 12 inches (300mm), the same length 400mm, crystal weight 81 kg of Czochralski crystal has been Beijing non-ferrous metals The successful development of the National Engineering Research Center for Semiconductor Materials of the Research Institute has made our country one of the few countries in the world with this capability. Beijing Nonferrous Metal Research Institute of semiconductor materials National Engineering Research Center, is China’s semiconductor materials research and development of the main base, respectively, in 1992 and 1995 have successfully drawn the first domestic diameter of 6 inches, 8 inches Czochralski crystal , And in 1995 built China’s first 6-inch diameter silicon polishing film production line. Products sold at home and abroad, made significant economic benefits and
