最近,日本东芝公司应用完美晶体(无位错、无缺陷的晶体)对完美晶体器件技术进行了研究,并且应用该技术使低噪声线性集成电路和晶体管达到了商品化程度。下面介绍一下该技术的情况。首先要明确什么是完美晶体器件技术,它的基本概念是把基极和发射极区域尽可能地形成完美晶体或接近完美晶体状态。完美晶体有两个条件,其一是无位错(<500/厘米~2)其二是无缺陷。 Recently, Toshiba Corp. of Japan applied perfect crystal (dislocation-free, defect-free crystals) to study perfect crystal device technology, and applied this technique to commercialize low-noise linear integrated circuits and transistors. Here's the situation of the technology. The first thing to be clear about is the perfect crystal device technology. Its basic concept is to make the base and emitter regions as perfect or nearly perfect as possible. Perfect crystal has two conditions, one is no dislocation (<500 / cm ~ 2) The other is defect-free.
