Description
前記配線が、前記エッチング領域の前記底面に露出している前記再配線層の絶縁層の少なくとも一部を覆っておらず、前記エッチング領域が、絶縁材料からなる第1の保護膜を介して、金属材料からなる第2の保護膜で覆われている。
図1〜図4に示すように、第1実施形態の撮像装置1は、シリコン層10と再配線層20と接着層30と透明部材であるカバーガラス40とを具備する。
次に、第1実施形態の変形例の撮像装置1Aについて説明する。撮像装置1Aは、第1実施形態の撮像装置1と類似しているので、同じ機能の構成要素には同じ符号を付し説明は省略する。
次に第2実施形態の撮像装置1Bについて説明する。撮像装置1Bは、第1実施形態の撮像装置1と類似しているので、同じ機能の構成要素には同じ符号を付し説明は省略する。
次に、第2実施形態の変形例の撮像装置1C〜1Eについて説明する。変形例の撮像装置1C〜1Eは、第2実施形態の撮像装置1Bと類似しており、撮像装置1Bの効果を有するので、同じ機能の構成要素には同じ符号を付し説明は省略する。
撮像装置1Bでは貫通孔10Hはウエットエッチングにより形成されたため、壁面はテーパー形状であった。これに対して、図12Aおよび図12Bに示す変形例1の撮像装置1Cでは、貫通孔10HCはドライエッチングで形成されるため、その壁面は略垂直である。
撮像装置のガードリングは、側面からの水分の浸入を防止することができるのであれば、その形状は問わない。また、再配線層20の作成時に同時に形成されてもよいし、再配線層20を貫通するトレンチを用いて配設してもよい。
次に、第3実施形態の内視鏡2を含む内視鏡システム9について説明する。
