三重扩散 meaning in Chinese

triple diffusion

With powerful technology and advanced devices , adopted the special process , the products of sisemi have excellent high - temperature characteristic and reliability . sisemi has become a famous supplier of silicon power transistors for green illumination application in china
近年来，在吸收、消化引进技术的基础上，不断创新，深爱公司在4英寸生产线上采用三重扩散sipos钝化高压平面工艺稳定进行高压双极型器件规模化生产的工艺，荣获深圳市科技进步奖。
In the new structure , a n + buffer layer is introduced into the bulk silicon substrate with a triple - diffusion process . . the new structure has two features : one is the feature of npt - igbt : the thin and lightly - doped p + layer and the high lifetimes of the carriers ; the other is the feature of pt - igbt : n7n + structure which can make the n " region very thin
新结构用三重扩散的方法在n ~ -单晶片上引入了n ~ +缓冲层，仍然保留了npt - igbt中薄而轻掺杂p层和高载流子寿命的本质优点，同时又具有pt - igbt中n ~ - ( n ~ + )双层复合的薄耐压层(即薄基区)的优点。
