Description
1.第1の実施の形態
2.第2の実施の形態
3.第3の実施の形態
[固体撮像装置の構成]
図1は本発明の第1の実施の形態に係る固体撮像装置の構成を示す要部断面図である。固体撮像装置1は、例えば、CMOSイメージセンサとして用いられるものである。固体撮像装置1は、平面的に見て、画素領域2と、周辺回路領域3と、外部接続領域4とを有している。画素領域2には、画素単位で、複数の受光部5と複数のマイクロレンズ6が、それぞれ二次元的に配置されている。周辺回路領域3には、図示はしないが、垂直方向及び水平方向で画素を選択するための垂直駆動回路、水平駆動回路等が配置される。また、画素領域2及び周辺回路領域3には、それぞれトランジスタTr1,Tr2,Tr3が形成されている。なお、図1においては、トランジスタTrのゲートのみを示している。
続いて、本発明の第1の実施の形態に係る固体撮像装置の製造方法について説明する。まず、図2(A)に示したように、保持基板31と、埋め込み酸化層32と、半導体層33とを順に積層した構造のSOI(Silicon On Insulator)基板に、例えばドライエッチング法で溝34を形成する。溝34は、半導体層33を貫通する状態で形成する。また、溝34は、後述する開口部32の周辺に位置するように、連続した枠状に形成する。保持基板31は、例えば、厚みが約700μmのシリコン基板からなる。埋め込み酸化層32は、例えば、厚みが例えば1μm〜2μmの酸化シリコン層からなる。半導体層33は、例えば、厚みが1μm〜20μm程度のシリコン層からなる。半導体層33は、上述した半導体素子層7に対応する層となる。
図14は本発明の第2の実施の形態に係る固体撮像装置の構成を示す要部断面図である。図示した固体撮像装置1においては、上記第1の実施の形態と比較して、特に、外部接続電極17aの構造が異なっている。即ち、上記第1の実施の形態においては、外部接続電極17aが平坦な構造が形成されているが、第2の実施の形態においては、外部接続電極17aは、開口部22の開口縁側(図の上側)に向かって凸の形状に形成されている。そして、外部接続電極17aの凸面が開口部22の底部で露出した状態に配置されている。
図16は本発明の第3の実施の形態に係る固体撮像装置の構成を示す要部断面図である。図示した固体撮像装置1においては、上記第1の実施の形態と比較して、特に、開口部22の構造が異なっている。即ち、上記第1の実施の形態においては、第1の開口部22aと第2の開口部22bを、互いに共通の中心をもつ矩形状に形成しているが、第3の実施の形態においては、少なくとも一つの開口部22に関して、第1の開口部22aを部分的に拡大して形成している。このため、図の左右方向のうち、右側においては、第2の開口部22bの縁から第1の開口部22aの縁までの距離がL1になっており、左側においては、第2の開口部22bの縁から第1の開口部22aの縁までの距離が上記L1よりも長いL2になっている。このような構造の開口部22は、例えば、図17に示すように、固体撮像装置1の外周部に所定の間隔で複数の開口部22を配列する場合に、4つのコーナー部(最端部)に配置される開口部22だけに適用する。この場合は、各々のコーナー部に配置される開口部22とそれ以外の開口部22で、第1の開口部22aの大きさが異なるものとなる。即ち、コーナー部に配置される開口部22は、それ以外の開口部22よりも第1の開口部22aが大きく形成される。
