Abstract :
Temperature distribution on the emitter fingers of heterojunction bipolar transistors (HBTs) is studied with a three-dimensional thermal-electrical model. Using this model, multi-finger HBTs is designed with non-uniform spacing. An efficient design procedure is presented. The calculated results show significant temperature reduction on non-uniform spacing devices.
