The physical mode and theory of the heat transfer in micro-bridge structure are introduced.A kind of micro-bridge pixel is provided with thick-film pixel size of 360μm×360μm and"desk-type"adiabatic frame support

and the analysis results by FEM show that the thermal conductivity G is small and high response rate can be obtained.The micro-bridge structure plays 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.
