Abstract
This paper reviews special RF/microwave silicon device implementations in the back-wafer contacted Silicon-On-Glass (SOG) Substrate-Transfer Technology (STT) developed at DIMES. In this technology, metal transmission lines can be placed on the low-loss glass substrate, while the resistive/capacitive parasitics of the silicon devices can be minimized by a direct two-sided contacting. Focus is placed here on the device level aspects of the SOG process. In particular, complementary bipolar device integration and high-quality varactors for high-linearity adaptive circuits are treated in relationship to developments in back-wafer contacting and the integration of AlN heatspreaders.
