Description
図1は、本発明の第1の実施形態に係わる撮像素子の概略側断面図である。撮像素子100は、例えばCMOS撮像素子であり、複数の画素が2次元状に配置された撮像面を有する撮像チップ101が、凹形状を有する支持基板102上に搭載されている。撮像チップ101は、図1のように周辺部が持ち上がった湾曲形状を有する。支持基板102と撮像チップ101との間隙には、例えば接着層103が充填され、湾曲形状を保つように撮像チップ101が支持されている。
図5は、本発明の第2の実施形態に係わる撮像素子の概略側断面図である。撮像素子500は、例えばCMOS撮像素子であり、複数の画素が2次元状に配置された撮像面を有する撮像チップ501が、凹形状を有する支持基板502上に搭載されている。撮像チップ501は、図5のように球面状の湾曲形状を有する。支持基板502と撮像チップ501との間隙には、例えば接着層503が充填され、球面状の湾曲形状を保つように撮像チップ101が支持されている。図5のように、撮像チップ501が球面状の湾曲形状を有することにより、撮像面の周辺部においても、撮影レンズを通過した光が撮像面と直交する方向に近い状態で画素に入射する。そして、受光面における光量ムラを抑制することができる。
