Description
F.Ren 外、“GaAs−AlGaAsヘテロ接合バイポーラトランジスタ構造のイオン注入分離”Applied Physics Letters ,56巻 9号 860乃至862 頁(1990年2月26日)
F.Ren 外はヘテロ接合バイポーラトランジスタ(HBT)中のエッジ終端に対するイオン注入損傷の使用について記載している。イオン注入はMESFET(金属・半導体電界効果トランジスタ)およびHEMT(高電子またはホール移動度トランジスタ)において広く使用され、それにおいては終端される層は比較的浅い。しかしながら、イオン注入は半導体の厚い層が分離される場合には適合が困難になる。またイオン注入のみの使用はHBTのような高ドープ層が存在し、装置が高い電圧に耐えることが期待されている場合にはエッジ終端装置を形成するのに不十分である。
(1)図1に示されたメサ終端を生成するためにコレクタ層を基体までエツチングするか、または、
(2)図2に示されているようにイオン注入を使用して装置のエッジを越えて領域を絶縁性にする。
