図1には、本考案の半導体装置に係る一実施形態の断面図が示されている。半導体装置101は、金属ブロック1と、半導体素子10と、絶縁基板21の一方の主面に第1金属層22と他方の主面に第2金属層23を有する絶縁回路基板20と、金属板30と、ボンディングワイヤ41と、外部端子51と、ケース70と、封止樹脂82とを備える。
図2には、本考案の半導体装置に係る他の実施形態の断面図が示されている。半導体装置102には、第1金属層に穿設された孔に、錫めっきされたピン端子52を挿入し、熱処理して拡散接合した絶縁回路基板20が用いられている。半導体装置102は、外部回路との接続にピン端子52を用いる点を除いて、他の部材の形態は半導体装置101と共通するため、金属ブロック1を配置することによって、封止樹脂の剥離を抑制できるという、実施形態1と同様の作用効果がもたらされる。ピン端子52を使用することにより、半導体装置102のユーザーは、組立が容易な、差込み式の実装方式を選択することができる。
図3には、本考案の半導体装置に係る更に他の実施形態の断面図が示されている。半導体装置103は、半導体装置102を原型としており、封止樹脂82に機械的強度の高い熱硬化性樹脂(例えばエポキシ樹脂)を用いてケース70を廃し、低コスト化したものである。その他は半導体装置102と共通するため、金属ブロック1を配置することによって、封止樹脂の剥離を抑制できるという、実施形態2と同様の作用効果がもたらされる。
図4には、本考案の半導体装置に係る更に他の実施形態の断面図が示されている。半導体装置104は、半導体装置103を原型としており、金属板30を廃し、第2金属層23の下面を封止樹脂82の外に露出させて、低コスト化したものである。その他は半導体装置103と共通するため、金属ブロック1を配置することによって、封止樹脂の剥離を抑制できるという、実施形態3と同様の作用効果がもたらされる。
図5には、本考案の半導体装置に係る更に他の実施形態の断面図が示されている。半導体装置105は、半導体装置104を原型とし、ボンディングワイヤ41をプリント基板42と導電性ポスト44とに変えたものである。プリント基板42の下面に配置された銅箔回路パターン(図示しない)は、半導体素子10や導電性ポスト44と半田を介して導電接続されている。また、導電性ポスト44の他方の端は、第1金属層22と導電接続されている。プリント基板42を用いることにより、ボンディングワイヤを使用する場合に比べて組立作業時間を短縮し低コスト化できる。その他は半導体装置104と共通するため、金属ブロック1を配置することによって、封止樹脂の剥離を抑制できるという、実施形態4と同様の作用効果がもたらされる。
図6には、本考案の半導体装置に係る更に他の実施形態の断面図が示されている。半導体装置106は、半導体装置104を原型とし、ボンディングワイヤ41をリードフレーム43に変えたものである。リードフレーム43を用いることにより、ボンディングワイヤを使用する場合に比べて組立作業時間を短縮し低コスト化できる。その他は半導体装置104と共通するため、金属ブロック1を配置することによって、封止樹脂の剥離を抑制できるという、実施形態4と同様の作用効果がもたらされる。
