Description
第2の開示に係る半導体装置では、貫通孔は、庇部の下面から延び下面から離れるほど幅が狭まる第1部分を有する。従って、樹脂の気泡を抜き易くできる。
第3の開示に係る半導体装置では、貫通孔の入り口を形成する庇部の縁は丸みを帯びている。このため、気泡が庇部の縁に引っ掛かることを抑制できる。従って、樹脂の気泡を抜き易くできる。
図1は、実施の形態1に係る半導体装置100の平面図である。半導体装置100は例えば電力変換装置である。半導体装置100はケース10を備える。ケース10は例えばインサートケースである。ケース10には端子30、32が取り付けられている。端子30は例えば信号端子である。端子30はケース10の長辺に設けられる。端子32は例えば大電流が流れる主端子である。端子32はケース10の短辺に設けられる。ケース10の形状、端子30、32の種類、形状、配置、数は図1に示されるものに限らない。
図8は、実施の形態2に係る半導体装置300の断面の拡大図である。半導体装置300はケース310を備える。ケース310は壁部分311と庇部312を有する。庇部312には貫通孔314が形成される。本実施の形態では、貫通孔314の形状が実施の形態1と異なる。他の構成は実施の形態1と同様である。
図10は実施の形態3に係るケース410の断面の拡大図である。ケース410は壁部分411と庇部412を有する。庇部412には貫通孔414が形成される。本実施の形態では、貫通孔414の形状が実施の形態1と異なる。他の構成は実施の形態1と同様である。
