The Micro-bridge structure pays an important role in the mechanical support, thermal isolation and electrical connection for the UFPA detector, the quality of which has a direct effect on the imaging performance of the UFPA detector. A kind of Micro-bridge pixel is provided in this paper with thick-film pixel size of 360μm×360μm and desk-type adiabatic frame support, and the analysis results by FEM show that the minor thermal conductivity G and high responsivity can be obtained.
