近日,北京有色金属研究总院研制成功了我国第一根直径18英寸(450毫米)直拉硅单晶和第一根直径12英寸红外光学锗单晶。直径18英寸直拉硅单晶的研制成功,将对提高我国半导体材料工业的研究水平、推动集成电路和信息产业的发展产生积极影响,标志着我国大直径硅单晶研究进入世界领先行列。锗单晶广泛应用于国防先进武器装备以及激光加工领域。目前,国外资料报道的锗单晶最大直径在12-13英寸范围,主
Recently, Beijing Nonferrous Metal Research Institute successfully developed China’s first 18-inch diameter (450 mm) Czochralski crystal and the first 12-inch diameter infrared optical germanium single crystal. The successful development of a diameter of 18-inch Czochralski silicon crystal will have a positive impact on improving the research level of China’s semiconductor material industry and promoting the development of integrated circuits and information industries, marking that China’s large-diameter silicon single crystal research has entered the world’s leading ranks. Germanium single crystal is widely used in national defense advanced weaponry and laser processing. At present, foreign materials reported single crystal germanium maximum diameter in the 12-13 inch range, the main
