一般的硅片(wafer)基材(substrate)可区分为N,P两种类型(type),何谓 N, P-type wafer?相关知识点: 试题来源: 解析 N-type wafer 是指掺杂 negative元素(5价电荷元素,例如:P、As)的硅片, P-type 的wafer 是指掺杂 positive 元素(3价电荷元素, 例如:B、In)的硅片。
N-Type Wafer Pure silicon is not conductive and therefore is rarely used as semiconductors. In order to make pure silicon into practically usable semiconductors, a controlled quantity of impurities must be added. The addition of impurity will change the conductivity and make the silicon into a ...
