This is accomplished by using heterostructure confinement in the emitter, introducing an energy barrier to minority-carrier charge flow from the base. This is important as loss of minority carriers from the base to the emitter degrades analog performance. The main difference of the HEBT from the Heterojunction bipolar transistor (HBT) is that the emitter–base interface is the same as in a bipolar junction transistor (BJT) with the blocking energy gap being moved back into the emitter bulk region. ==Functional Architecture== The main advantage of HEBT architecture, compared to the HBT is a simplified fabrication process for the emitter–base junction. In particular the HEBT does not require as tight parametric control during epitaxial growth, that equivalent abrupt or graded emitter structures might. This is very important as it is evident from scanning ion mass spectrometry data that out-diffusion base dopant into the emitter junction is difficult to control, as the base is, in general, very highly doped in order to enhance performance. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Heterostructure-emitter bipolar transistor」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
