Description
図1は実施形態の半導体装置100の断面図を示す。半導体装置100は、例えばコントローラチップである半導体素子と例えば半導体メモリチップである半導体素子を含んだ半導体パッケージである。より具体的には、半導体装置100は、例えば、いわゆるBGA-SSD(Ball Grid Array-Solid State Drive)であり、複数の半導体メモリチップとコントローラとが一つのBGAタイプのパッケージとして一体に構成される。
図3に示す半導体装置101は、コントローラチップ4の一部が第1樹脂組成物3及び第2樹脂組成物14に一部埋め込まれて、封止されている。コントローラチップ4の一部が埋め込まれることで、メモリチップを図1の形態の半導体装置100よりもコントローラチップ4側に配置させることで、半導体装置101の幅(X方向の距離)をより狭くすることが出来る。コントローラチップ4が大型化しても、かかる構造であれば、半導体装置101の幅を狭くし、半導体装置101の小型化に貢献する。第5ボンディングワイヤ5の一部又は全部は、第1樹脂組成物3に埋め込まれている。第6ボンディングワイヤ15の一部又は全部は、第2樹脂組成物14に埋め込まれている。
