  • Patent number: 7172920
    Abstract: An imaging device comprises a select line, a first signal line crossing the select line, and a first pixel provided at a portion corresponding to a crossing portion of the select line and the first signal line, the first pixel comprising a first buffer layer formed on a substrate, a first bolometer film formed on the first buffer layer, made of a compound which undergoes metal-insulator transition, and generating a first temperature detection signal, a first switching element formed on the substrate, selected by a select signal from the select line, and supplying the first temperature detection signal to the first signal line, and a metal wiring connecting a top surface of the first bolometer film to the first switching element.
