Description
(実施の形態1)
図1は、本発明の実施の形態1に係る半導体装置の構成を示す概略図である。図1に示す半導体装置10は、電力用であり、接続する負荷に電力を供給する電力素子1と、電力素子1を制御する回路素子2とを同一の半導体基板3に形成してある。さらに、半導体基板3には、電力素子1を形成した一面に、電力素子1および回路素子2に対し独立して配置したp型の半導体層4が形成してある。
実施の形態1に係る半導体装置10では、負電流が流れた場合、半導体層4に構成されるダイオード8の順方向に電流が導通し、ダイオード8を流れる電流が増加する。ダイオード8を流れる電流が増加すると、抵抗素子9bによる電圧降下によってダイオード9cのアノード電極の電位(半導体層4の電位)が下がる。
外部回路9の一部構成を半導体基板3内に形成する場合について説明する。図5は、本発明の実施の形態3に係る半導体装置の回路構成を示す回路図である。図5(a)に示す半導体装置10aは、図2に示す半導体装置10の外部回路9の一部構成を半導体基板3内に形成してある。具体的に、半導体装置10aは、抵抗素子9bおよびダイオード9cを半導体基板3に形成してある。抵抗素子9bは、半導体基板3にポリシリコン膜を形成することで構成し、ダイオード9cは、半導体基板3に注入する不純物の濃度を拡散することで構成してある。
図6は、本発明の実施の形態4に係る半導体装置の構成を示す概略図である。図6に示す半導体装置40は、電力用であり、接続する負荷に電力を供給する電力素子1と、電力素子1を制御する回路素子2とを同一の半導体基板3に形成してある。
図8は、本発明の実施の形態5に係る半導体装置の構成を示す概略図である。図8に示す半導体装置50は、電力用であり、接続する負荷に電力を供給する電力素子1と、電力素子1を制御する回路素子2とを同一の半導体基板3に形成してある。さらに、半導体基板3には、電力素子1を形成した一面に、電力素子1および回路素子2に対し独立して配置したp型の半導体層4が形成してある。また、半導体装置50は、半導体層4内に、n型の半導体層21を形成してある。
図10は、本発明の実施の形態6に係る半導体装置60の回路構成を示す回路図である。図10に示す半導体装置60は、外部回路9以外の構成が実施の形態5に係る半導体装置50と同じであるため、半導体装置50と同じ構成要素について同じ符号を付して、詳細な説明を省略する。
