Abstract：

A　novel　multi-finger　power　SiGe　heterojunction　bipolar　transistor　(HBT)　with　segmented　emitter　and　non-uniform　finger　spacing　structure　is　proposed　to　improve　thermal　stability　of　HBT.　Thermal　simulation　for　a　ten-finger　power　SiGe　HBT　with　novel　structure　are　conducted　with　ANSYS　software.　Three-dimensional　temperature　distribution　on　emitter　fingers　is　obtained.　Compared　with　traditional　integrity　structure　or　segmented　emitter　and　uniform　finger　spacing　structure,　the　maximum　junction　temperature,　temperature　distribution　and　heat-flux　distribution　are　significantly　improved.　Thermal　stability　is　effectively　enhanced.
