Description
図1は、実施の形態1に係る半導体装置を示す平面図である。図2は、図1のI-IIに沿った断面図である。図3は、図1のIII-IVに沿った断面図である。ヒートシンク1は、実装面である上面1aと、放熱面である下面1bと、互いに直交する第1の側面1cと第2の側面1dとを有する。図面においてヒートシンク1の上面1aと下面1bはZ方向で互いに対向する。第1の側面1cはY方向で互いに対向する2つの側面である。第2の側面1dはX方向で互いに対向する2つの側面である。
図9は、実施の形態2に係る半導体装置を示す断面図である。この断面図は実施の形態1の図2に対応する。実施の形態1では放熱面であるヒートシンク1の下面は平坦である。一方、本実施の形態ではヒートシンク1の下面に凹部14が設けられている。凹部14はモールド樹脂10で充填されている。これにより、アンカー効果を更に高めることができる。その他の構成及び効果は実施の形態1と同様である。
図10は、実施の形態3に係る半導体装置を示す断面図である。この断面図は実施の形態1の図2に対応する。本実施の形態では、リード端子5,6の下方においてヒートシンク1の第2の側面1dに突起物15が設けられている。ヒートシンク1をモールド成型用の下側金型内にセットする際に、突起物15によりセルフアライメント機能が働く。従って、ヒートシンク1の第2の側面1dの下端とモールド樹脂10の側面10aの下端との距離Dの制御性が向上するため、リード端子5,6のインピーダンスのバラつきを抑えることができる。その他の構成及び効果は実施の形態1と同様である。
