Description
Transistor)1は、例えば周知のHEMT(High Electron Mobility Transistor)からなる。すなわち、窒化物FETはAlxInyGa1−x−yN(0≦x≦1、0≦y≦1、0≦x+y≦1)で表わされる窒化物半導体層からなる活性領域11を備え、活性領域11の主面上に形成されたドレイン電極(第1の主電極)D、ソース電極(第2の主電極)S及びゲート電極(制御電極)Gを備える。活性領域11は、Siからなる導電性基板上に緩衝層を介して配置される。ドレイン電極Dとソース電極Sとは、活性領域11上において互いに離間して配置されるとともに、平面的に見て、互いに入り組んだフィンガ型の電極構造を有する。ゲート電極Gは、ドレイン電極Dとソース電極Sとの間に配置され、上記フィンガ型の電極構造に合わせて折り返し構造を有する。また、窒化物FET1は、活性領域11上に形成されたドレイン電極Dに電気的に接続されるドレインパッド12、ソース電極Sに電気的に接続されるソースパッド13及びゲート電極Gに電気的に接続されるゲートパッド14を備える。なお、図示は省略するが、各電極並びにパッドが形成されない活性領域11の主面と各電極の上面とは、絶縁物からなる保護膜により被覆される。
