Abstract:
A semiconductor device comprising a power amplifying bipolar transistor with an emitter grounded, a current mirror circuit including a bipolar transistor for supplying a base voltage to said power amplifying bipolar transistor, and a thermal linkage structure formed between a junction temperature of the power amplifying bipolar transistor and a junction temperature of the bipolar transistor included in the current mirror circuit;wherein said thermal linkage structure comprises an inter-layer insulating film laminated on said power amplifying bipolar transistor and a metallic wire which is laminated on said inter-layer insulating film electrically connecting an emitter electrode of said power amplifying bipolar transistor to a ground via a through hole formed in said inter-layer insulating film, and which is extended to the neighborhood of said bipolar transistor included in said current mirror circuit.
