Abstract:
An array of infrared (IR) sensors, comprising:plural first IR sensors on one substrate and plural second IR sensors on said one substrate, said first IR sensors detecting IR rays of a first wavelength band and said second IR sensors detecting IR rays of a second wavelength band different from said first wavelength band, said first and second IR sensors each comprising a diaphragm that is separated from said one substrate by a hollow cavity that isolates said substrate from said diaphragm, said diaphragm in each of said first and second IR sensors including a bolometer material film, said diaphragm in each of said first IR sensors having a first thickness and said diaphragm in each of said second IR sensors having a second thickness different from said first thickness, and said cavity in each of said first and second IR sensors having the same height.
