最近,国外正在研究采用激光调整晶体管的少子寿命及放大倍数。采用激光降低少子寿命(可达几个数量级)的方法可达到不用掺金而提高开关速度的目的,这种方法常用于线性电路和开关电路的混合电路。采用激光退火使多晶硅单晶化,然后在此退火的多晶硅上制作 Recently, foreign countries are studying the use of laser to adjust the life of the transistor and the amplification factor. The method of using lasers to reduce the lifetime of a minority carrier (up to several orders of magnitude) can achieve the purpose of increasing the switching speed without using gold. This method is commonly used in the hybrid circuits of the linear circuit and the switching circuit. Polysilicon is single-crystalized by laser annealing, and then annealed on the polysilicon
