IBM公司在瑞士吕施孔利的一个实验室,成功地在直径5厘米的半导体晶片上制造了2万个长度不到1毫米的微型激光器。在一块晶片上制造出如此多的半导体激光器在世界上尚属首次。微型半导体激光器广泛用于磁盘读出、文本打印、光通信及计算机内存数据的存取。同传统制造方法相比,IBM公司的集成新技术更 At a lab in Rüchigli, Switzerland, IBM successfully manufactured 20,000 20,000-mm-long microscopic lasers on a 5-centimeter-diameter semiconductor wafer. This is the first time in the world that so many semiconductor lasers have been fabricated on a single wafer. Micro-semiconductor lasers are widely used for disk readout, text printing, optical communications and computer memory data access. Compared with traditional manufacturing methods, IBM’s integrated new technology more
