摘要:
A method to produce a nitride semiconductor device is disclosed, The method includes a step to grow sequentially, on a substrate, an AlN layer, a AlGaN layer with the Al composition not less than 2.5% but not greater than 9%, a GaN layer with a thickness not less than 250 nm but not greater than 1400 nm. A feature of the process is that, after the growth of the AlGaN layer but before the growth of the GaN layer, at least the source gases for the group III elements are interrupted to be supplied for a period of not less than 80 seconds but not longer than 220 seconds.
摘要(中):
公开了一种制造氮化物半导体器件的方法。该方法包括在衬底上AlN层,Al组成不超过2.5%但不大于9%的AlGaN层依次生长的步骤,GaN层 厚度不小于250nm但不大于1400nm。 该方法的特征在于,在AlGaN层生长之后但是在GaN层生长之前,至少III族元素的源气体被中断以供给不少于80秒但不是 超过220秒。
