Abstract
We present a study of thermal resistance in trench-isolated Si/SiGe heteroj unction bipolar transistors (HBTs), using a technique based on isothermal c ollector current measurement. Measured thermal resistance is in good agreem ent with a realistic three-dimensional (3-D) numerical model; emitter metal lization, shallow trenches, and heat flow through the deep trench walls are all shown to have a significant effect on the thermal resistance.
