Claims (1)
- 半導体基板の一表面側において赤外線を吸収して熱に変換する赤外線吸収部と赤外線吸収部の温度変化を検出する感温部とが半導体基板の厚み方向に離間して配置され、赤外線吸収部が赤外線吸収部と感温部とを熱的に結合する熱伝達部を介して感温部に支持された赤外線センサであって、赤外線吸収部は、赤外線の入射面に平行な2次元面内に屈折率周期構造を有し赤外線を吸収する単層の吸収構造体からなり、当該屈折率周期構造が、検出対象の赤外線の波長帯に対して共振ピークを有するように設計されており、検出対象の赤外線の波長に共振し当該赤外線を定在させる共振器を構成しており、吸収構造体は、赤外線吸収材料からなるスラブに複数の空孔を周期的に設けることで前記屈折率周期構造が形成されてなることを特徴とする赤外線センサ。
