Description
各画素領域101は、列(column)(例えばC1〜Cx)および行(row)(例えばR1〜R y )に配置される。用語“画素領域”は、機構(例えば光検出器および各種回路)を含むユニットセルを指し、電磁放射を電気信号に変換する各種の半導体デバイスを含むことができる。画素領域101の光検出器は、フォトダイオード、相補型金属酸化物半導体(CMOS:complimentary metal-oxide semiconductor)イメージセンサ、電荷結合素子(CCD:charged coupling device)センサ、アクティブセンサ、パッシブセンサ、および/または他のセンサを含むことができる。画素領域101は、各種のセンサタイプを有するように設計されることができる。例えば、画素領域101の1つのグループは、CMOSイメージセンサであることができ、画素領域101のもう1つのグループは、パッシブセンサであることができる。描かれた実施形態では、各画素領域101は、フォトゲートタイプの光検出器などの光検出器を含むことができ、光(放射)の強度または輝度を記録する。各画素領域101は、例えば、転送トランジスタ、リセットトランジスタ、ソースフォロアトランジスタ、選択トランジスタ、他の好適なトランジスタ、またはその組み合わせなどの各種の半導体デバイスも含むことができる。付加の回路、入力、および/または出力は、イメージセンサデバイス100の周辺領域にあることができる。周辺領域のこれらの回路、入力、および/または出力は、画素領域101に接続され、画素領域101に動作環境を提供し、画素領域101との外部通信をサポートする。簡単にするために、単一の画素領域を含むイメージセンサデバイスが本説明書に述べられているが、一般的にこのような画素領域のアレイは、図1に示されたイメージセンサデバイス100を形成することができる。
