Patent ID: 6914245

Claim:
An infrared light detection array with a plurality of infrared light detectors arranged on a substrate in the form of a matrix, said infrared light detectors each comprising: a) a supporting leg fixed to said substrate at one end, having a laminated structure of an insulation layer and a wiring layer; b) a heat insulation structure portion supported by said supporting leg, comprising an insulation layer having a first surface to serve as a surface of incidence for infrared light to impinge on and a second surface to serve as a surface of incidence for reading light to impinge on, a reflection film which is formed on said second surface of said insulation layer, and a resistor connected with said wiring layer, and as said supporting legs heated up to a detection temperature by said infrared light reversibly warp, said infrared light detectors change the reflection direction of said reading light impinging upon said reflection films, wherein said supporting legs non-reversibly warp, as said resistors carry a current through said wiring layers and said supporting legs are heated up to a temperature higher than said detection temperature.
