Description
ソース電極22、ドレイン電極24を形成後、SiN(窒化ケイ素)やSiO2(二酸化ケイ素)などの保護膜30が形成される。続いて、保護膜30のゲート領域を、フッ素ガス(たとえばCF4やSF6等)を用いてドライエッチングし、エピタキシャル層14を露出させる。そしてゲート領域にNi/Au(ニッケル/銀)等のゲート電極20を形成する。ゲート電極20の断面はT字型であり、その端部において保護膜30にオーバーハングしている。
図2は、第1の実施の形態に係る半導体装置100の断面図である。半導体装置100は、ショットキーゲート構造のHEMT(High Electron Mobility Transistor、以下、単に第1トランジスタという)102を備える。
半導体装置100によれば、ゲート電極120の端部におけるオーバーハングを形成する必要がないため、製造工程においてフッ素系ガスを用いたドライエッチングが不要となる。これにより、GaNエピ層114内にフッ素が注入されるのを防止でき、ゲートしきい値VGS(th)の変動を抑制できる。
上述のように、第1トランジスタ102はゲートしきい値VGS(th)の安定性に優れるが、ゲートリーク電流の特性において、図1のトランジスタ4に劣っている。第2の実施の形態では、ひとつの半導体チップに、ゲートしきい値VGS(th)の安定性が要求されるトランジスタ(第1トランジスタという)と、低ゲートリーク電流特性および低電流コラプス特性が要求されるトランジスタ(第2トランジスタという)が集積化された半導体装置100Aを説明する。
続いて、半導体装置100Aの用途を説明する。図2の半導体装置100あるいは図6の半導体装置100Aは、RF回路(MMIC:Monolithic Microwave IC)に好適に用いることができる。図9は、RF回路500の一例を示す回路ブロック図である。
実施の形態に係る半導体装置100,100Aの用途はスイッチやセレクタ、スプリット機能を有するRF回路(MMIC)に限定されず、高周波アンプにも適用可能である。また高周波系ではなく、パワー系のICにも適用可能である。
