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。図2は、本発明の実施の形態1に係る半導体装置のケースを示す下面図である。放熱板1上に絶縁板2が設けられ、絶縁板2上に回路パターン3が設けられている。放熱板1と絶縁板2と回路パターン3は一体となっている。
図3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。図4は、本発明の実施の形態2に係る半導体装置のケースを示す下面図である。本実施の形態では、実施の形態1の素材12の代わりに、ケース6の下面に凹部13が環状に設けられている。ゴムなどの弾力性部材14がケース6の凹部13に環状に設けられ、絶縁板2の上面及びケース6の下面に密着している。凹部13に押し込まれていない状態の弾力性部材14の自然長は凹部13の深さより大きい。その他の構成は実施の形態1と同様である。
図5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。本実施の形態では、実施の形態1の素材12の代わりに、ケース6の下面に環状に設けられた凹部13に、絶縁板2の上面に環状に設けられた凸部15が嵌合している。凹部13及び凸部15は複数でもよいし、1つでもよい。その他の構成は実施の形態1と同様である。
図6は、本発明の実施の形態4に係る半導体装置を示す断面図である。実施の形態3の構成に加えて、凹部13内において凸部15の上に弾力性部材16が設けられている。弾力性部材16は例えば樹脂性のレジストである。弾力性部材16を設けることにより、実施の形態3よりも樹脂11の液漏れ効果を高めることができる。これによって樹脂11の粘度を下げることができるため、半導体装置の部品構想の幅が広がる。その他の構成及び効果は実施の形態3と同様である。
図7は、本発明の実施の形態5に係る半導体装置を示す断面図である。本実施の形態では、実施の形態1の素材12の代わりに、ケース6の下面に環状に設けられた凸部17が、弾力性を有する樹脂系などの絶縁板2に食い込んでいる。凸部17は複数でもよいし、1つでもよい。凸部17は断面が三角形状であり、先端は丸みを帯びていてもよい。その他の構成は実施の形態1と同様である。
図8は、本発明の実施の形態6に係る半導体装置を示す断面図である。本実施の形態では、実施の形態1の素材12の代わりに、絶縁板2の上面とケース6の下面との隙間に、例えば樹脂性のレジストインキなどの弾力性部材18が環状に設けられている。ケース6の下面に設けられた凸部17が弾力性部材18に食い込んでいる。凸部17は複数でもよいし、1つでもよい。凸部17は断面が三角形状であり、先端は丸みを帯びていてもよい。その他の構成は実施の形態1と同様である。
