Description
(半導体装置の構成)
図1は、第1の実施の形態に係る半導体装置1の垂直断面図である。
図3A(a)〜(c)、図3B(d)、(e)、図3C(f)は、第1の実施の形態に係る半導体装置1の製造工程を示す垂直断面図である。
第2の実施の形態は、半導体基板2の裏面に貫通孔30を埋めるように絶縁層が形成される点において第1の実施の形態と異なる。
第3の実施の形態は、貫通孔領域3における貫通孔のパターンにおいて第1の実施の形態と異なる。
第1〜3の実施の形態によれば、半導体基板2に貫通孔30を含む貫通孔領域3を形成することにより、MEMSキャパシタ20と半導体基板2との間に生じる寄生容量を低減することができる。このため、寄生容量を低減するための絶縁層13の厚さを小さくすることができ、MEMSキャパシタ20の下層に制御用集積回路8が形成される場合であっても、半導体基板2に生じる反りを抑えることができる。
本発明は、上記実施の形態に限定されず、発明の主旨を逸脱しない範囲内において種々変形実施が可能である。また、発明の主旨を逸脱しない範囲内において上記実施の形態の構成要素を任意に組み合わせることができる。また、半導体装置の製造工程の順序は、上記実施の形態に示されるものに限定されない。
