Description
しかしながら、第1樹脂部と第2樹脂部は通常、熱膨張係数が異なっているため、第1樹脂部と第2樹脂部との密着性が高いと、第2樹脂部からの応力を受けて、発光チップが剥離してしまうおそれがある。
前記第1半導体素子上に設けられた第2半導体素子と、
前記第2半導体素子の表面を覆うゲル状のシリコーンと、
前記シリコーンの表面と前記第1半導体素子の表面とを覆う樹脂部と、を備える半導体装置が提供される。
図1Aは本実施形態による光結合装置1の斜視図、図1Bは図1AのA−A線の断面図である。本実施形態による光結合装置1は、基板2上にそれぞれ離して配置される第1パッド3、第2パッド4および第3パッド5と、第1パッド3上に設けられる受光チップ6と、受光チップ6上に設けられる発光チップ7と、第2パッド4上に設けられる第1MOSFET(Metal Oxide Semiconductor Field Effect Transistor)8と、第3パッド5上に設けられる第2MOSFET9と、発光チップ7の表面を覆うゲル状のシリコーン10と、シリコーン10の表面を覆う樹脂部11とを備えている。第1MOSFET8と第2MOSFET9は、IGBT等のパワー半導体素子である。
第2の実施形態は、ゴム状のシリコーン10を用いて、発光チップ7の剥離を防止するものである。
