  • Abstract
    A new structure uncooled amorphous silicon (a-Si) microbolometer for infrared detection has been fabricated and characterized. Based on polyimide thermal isolation layer and bottom metal reflective structure, the newly presented bolometer has the advantage of low cost, high yield and high performance. The dependence of the temperature coefficient of resistance on operating temperature has been investigated. The results show that at a chopping frequency of 30Hz and a bias voltage of 5V, the maximum detectivity of 1.7 times 108 cmHzfrac12W-1 is achieved
