最近,美国罗切斯特大学研制成一种将硅发光元件与电气元件一体化的基片。因为发光元件一般采用钾、砷等化合物半导体,所以,不能与用硅制成的电气元件集成一体化。另外在价格方 Recently, the University of Rochester developed a silicon light-emitting components and electrical components integrated substrate. Since the light-emitting element generally uses a compound semiconductor such as potassium, arsenic and the like, it can not be integrated with the electric element made of silicon. Also in the price side
