Description
図1は、第1の実施形態による固体撮像装置の構成を模式的に示す断面図である。この固体撮像装置は、たとえばCMOSセンサである。固体撮像装置は、光電変換素子および光電変換素子の信号を読み出す素子を有する画素が形成される画素形成部10と、画素形成部10に形成された素子に接続される配線が形成される配線層20と、配線層20の上部を保護する保護膜51と、画素形成部10の各画素へ入射する光の波長を制限するカラーフィルタ31と、各画素に対して設けられるマイクロレンズ32と、を備える。
図10−1〜図10−2は、第2の実施形態による固体撮像装置の製造方法の手順の一例を示す断面図であり、図11は、図10−1(b)の上面図である。フォトニック結晶42以外の部分の製造方法については、従来の固体撮像装置と同様であるので、この第2の実施形態でも、フォトニック結晶42の部分の製造方法についてのみ説明する。
