Description
図1は第一の実施形態に係る受光デバイスの断面図(後述する図2の1−1線における断面図)である。この受光デバイスは、光電変換部101と、走査回路部102と、マイクロバンプ106とを有し、光電変換部101と走査回路部102とがマイクロバンプ106を介して積層されている、すなわち、この受光デバイスはいわゆる積層型のデバイスである。
図4は第一の実施形態の変形例に係る受光デバイスの断面図である。フィレットを形成する封止樹脂109の代わりに、フォトダイオード104の上面に対応する位置に開口部があり光電変換部101を包む容器120の側面上に、透明導電膜103が形成される。透明導電膜103は走査回路部102周囲の電極パッド110と接続されている。なお、容器120は走査回路部102の上に設けられており、容器120の側面はフォトダイオード104の上面に対し勾配、特に45°以下の勾配を有している。
図5は第二の実施形態に係る受光デバイスの断面図である。
