Abstract
【解決手段】 半導体装置10の半導体層12には、ダイオード領域20とIGBT領域40が形成されている。ダイオード領域20の半導体層12には、ライフタイム制御領域39が形成されている。そのライフタイム制御領域39は、ダイオード領域20とIGBT領域40の境界からIGBT領域40の一部に侵入するように連続して伸びている。ライフタイム制御領域39の先端39aは、平面視したときに、IGBT領域40のボディ領域46の形成範囲に位置する。
【選択図】図1
Description
(特徴1)ライフタイム制御領域は、荷電粒子の照射によって形成されており、半導体層の所定深さの面内の一部に形成されている。
(特徴2)ライフタイム制御領域の先端は、平面視したときに、IGBT領域の最もダイオード領域側に設けられているトレンチゲートを越えた範囲に位置している。ここで、トレンチゲートを超えた範囲とは、トレンチゲートの下方の範囲も含む。この場合のライフタイム制御領域は、IGBT領域の最もダイオード領域側に設けられているトレンチゲートよりもダイオード領域側に存在するボディ領域の下方の全域に形成されている。ダイオード領域に還流電流が流れているとき、トレンチゲートよりもダイオード領域側に存在するボディ領域で構成される寄生ダイオードが順バイアスされ易い。このため、上記位置関係に形成されたライフタイム制御領域は、IGBT領域の寄生ダイオードを介して注入されるキャリアを良好に消失させることができる。
また、本明細書または図面に説明した技術要素は、単独であるいは各種の組合せによって技術的有用性を発揮するものであり、出願時請求項記載の組合せに限定されるものではない。また、本明細書または図面に例示した技術は複数目的を同時に達成し得るものであり、そのうちの一つの目的を達成すること自体で技術的有用性を持つものである。
