Abstract
Description
そして、この熱センサを基板上にマトリクス状に多数形成することにより、赤外線イメージセンサやナイトビジョン装置等に組み込まれるセンサアレイが構成される。
また、熱センサをセンサエレメントとするセンサアレイでは、全体に対するメンブレン(感応部)の面積比率が低く、大型で且つ検出感度の劣るものとなる問題があった。
すなわち、フレーム片を共有(兼用)することは、例えば隣接するセンサエレメントが1つのフレーム片に対して、その面内の対向する方向からそれぞれ接続(接合)されるような位置関係であり、このような構成では、フレーム片がその両側にメンブレンを配置した構造となるので、フレーム片とメンブレンを一体としてその強度を高めることができる。また、フレーム部の面内方向における幅を各センサエレメントの長さよりも十分に小さくするように構成して、細いフレーム部とすることができるので、フレーム部の総面積に対するメンブレンの総面積の比率を高めることができる。
図7の変形例に係る赤外線センサ1は、第1実施形態と同様に、四角形の枠状に形成されたフレーム部2と、フレーム部2内に架設され、凹凸形状に形成されたメンブレン3と、を備えている。この第1変形例のメンブレン3は、凹凸形状が斜めに交差するように延在し、メンブレンの面内全域において、平面視三角形の凹部3aと凸部3bとが網目状に分布した形態となっている。この場合、補強リブとなる周壁3cが3方向に延在するため、より一層、メンブレン3の強度アップを図ることができる。
図8のセンサアレイ20は、各赤外線センサ1において、その凹部3aおよび凸部3bを平面視長方形に形成したものであり、複数の赤外線センサ(センサエレメント)1を隙間なく面状に配置して、構成されている。具体的には、複数の赤外線センサ1は、相互のフレーム部2を共有した状態で、すなわち、隣接する任意の2つの赤外線センサ1において、相互のフレーム片2aを共有した状態で配置されている。また、隣接する任意の2つの赤外線センサ1において、メンブレン3の凹凸形状の形態が異なっている。すなわち、一方のメンブレン3では、長方形の凹部3aおよび凸部3bがいわゆる横向きに配置され、他方のメンブレンで3は、長方形の凹部3aおよび凸部3bがいわゆる縦向きに配置されている。
