据东京日本新金属联合会硅委员会宣布,去年(1990年)日本硅晶体生产量是:多晶硅(硅锭)为2147吨,比1989年增长22％;单晶硅(硅锭)为1933吨,比1989年增长12％。按最初计划,1990年单晶硅和多晶硅产量都是只比1989年增长3％。硅委员会称,硅晶体产量这种意想不到的大幅度增长,主要是由于半导体芯片生产的增长、大直径硅圆片消耗量增大和用来制作4Mb According to Tokyo’s Japan New Metal Federation silicon committee announced last year (1990) Japan’s silicon crystal production is: polycrystalline silicon (silicon ingot) is 2147 tons, an increase of 22% over 1989; monocrystalline silicon (ingot) to 1933 tons, 12% more than in 1989. According to the original plan, monocrystalline silicon and polysilicon production in 1990 were only 3% more than in 1989. The Silicon Committee said the unexpected and substantial increase in silicon crystal production was largely due to the growth in semiconductor chip production, increased consumption of large-diameter silicon wafers and the production of 4Mb
