Abstract
Description
図1は、本発明の実施の形態1に係る半導体装置を示す断面図である。半導体素子1はIGBT(Insulated Gate Bipolar Transistor)などのパワー半導体素子である。半導体素子1の制御端子(ゲート)がワイヤ2を介して信号電極3に接続されている。半導体素子1の下面(コレクタ)が、絶縁板4上に設けられた回路パターン5を介して高圧電極6に接続されている。半導体素子1の上面(エミッタ)がはんだ7を介して高圧電極8に接続されている。
図2は、本発明の実施の形態2に係る半導体装置を示す断面図である。樹脂10の下面に凹部14が設けられ、接合材13が凹部14に回り込んでアンカーとなる。これにより、接合面積が増加するため、接合強度が向上する。その他の構成は実施の形態1と同様である。
図3は、本発明の実施の形態3に係る半導体装置を示す断面図である。本実施の形態は、冷却能力を向上させた両面冷却構造に本発明を適用したものである。
図3は、本発明の実施の形態3に係る半導体装置を示す断面図である。冷却フィン9は、セラミックの絶縁材20と高熱伝導性の導電材21のコンポジット構造である。その他の構成は実施の形態1と同様である。
