Abstract :
In this paper we investigated the self-heating effects in SiGe heterojunction bipolar transistors (HBTs) fabricated on SiGe alloy virtual substrate. Using a two-dimensional process and device numerical simulation, we have found that self-heating effects and local temperature increase due to the internal power dissipation are substantially more pronounced in virtual substrate HBTs in comparison with identical HBT devices on silicon substrate.
