Description
実施の形態1.
まず本実施の形態の半導体装置の構成について、図1〜図3を用いて説明する。なお図1は図2および図3の平面図の左右方向に延びる線に沿う断面図であり、概ね図1の左右方向が図2および図3の左右方向に対応している。ただし図2および図3において半導体素子4は左右方向に対してややずれた位置関係となるように並んでいるため、図1では部分的に図2および図3の平面図を半導体素子が左右方向に沿って並ぶように修正された構成となっている。
図9を参照して、本実施の形態の半導体装置201は、基本的に実施の形態1の半導体装置101と同様の構成を有するため、同一の構成要素には同一の符号を付しその説明を繰り返さない。ただし半導体装置201においては、半導体素子4の上方に接続される導体基板3P1が、他の部材と併せて第2の絶縁基板としての絶縁基板3を構成している。この点において半導体装置201は、半導体素子4の上方に接続される導体基板3Pが、他の部材から独立しそれ単体でリードフレームなどの金属導体部材を構成する実施の形態1の半導体装置101と、構成上異なっている。
本実施の形態は、上述した実施の形態1〜2にかかる半導体装置を電力変換装置に適用したものである。本発明は特定の電力変換装置に限定されるものではないが、以下、実施の形態3として、三相のインバータに本発明を適用した場合について説明する。
