Description
図1〜図4を参照しながら、本発明に係るケース型半導体装置(パワーモジュール)の実施の形態1について以下に説明する。図1に示す実施の形態1のパワーモジュール1は、概略、樹脂などの絶縁材料からなる樹脂ケース10と、良好な熱伝導性を有する銅などの金属板からなるベース板(ヒートシンク)12と、樹脂ケース10の上面から内部に延びる複数の外部端子14とを備えている。樹脂ケース10は、その底面において、ねじまたは接着剤(図示せず)を用いて、ベース板12上に固定されている。
次に、図5を参照しながら、本発明に係るパワーデバイスの実施の形態2について以下に説明する。図5に示すパワーデバイス2の半導体チップ22は、低帯電部38が周縁領域32の外側部分にしか形成されていない点以外は、実施の形態1と同様の構成を有するので、重複する部分に関する詳細な説明を省略する。
図6を参照しながら、本発明に係るパワーデバイスの実施の形態3について以下に説明する。図6に示すパワーデバイス3は、概略、低帯電部38が一部の周縁領域にしか形成されない点を除き、実施の形態1と同様の構成を有するので、重複する部分に関する詳細な説明を省略する。
実施の形態3の低帯電部38は、導電性ワイヤ42に対向する導電性リングの一部(第1の周縁領域)だけを覆い、第2の周縁領域56を覆わないように形成される。すなわち、実施の形態3のガードリングは、第1の周縁領域54では低帯電部38と導電性リング36とから構成され、第2の周縁領域56では導電性リング36と封止部44とから構成される。
図7を参照しながら、本発明に係るパワーデバイスの実施の形態4について以下に説明する。図7に示すパワーデバイス4は、導電性ワイヤ60がガードリングの上方を横断することなく上方に延び、かつ低帯電部38が形成されない点を除き、実施の形態1と同様の構成を有するので、重複する部分に関する詳細な説明を省略する。
