This paper introduced a new DC technique for the measurement of the thermal resistance of HBTs. The method is very simple, because it requires only standard IC-VCE measurements at different baseplate temperatures, and it is able to account for the dependence of the thermal resistance on both the base-plate temperature and the dissipated power. We have obtained and shown consistent results extracted from devices with emitter area ranging from 90 μm2 (1 finger) to 1080 μm2 (12 fingers).
