Pushing the performance limits of SiGe HBT technology

View publication


The implementation of challenging novel materials and process techniques has led to remarkable device improvements in state-of-the-art high-performance SiGe HBTs, rivaling their III-V compound semiconductor counterparts. Vertical scaling, lateral scaling, and device structure innovation required to improve SiGe HBTs performance have benefited from advanced materials and process techniques being developed for next generation CMOS technology. In this work, we present a review of recent process and materials development enabling operational speeds of SiGe HBTs in excess of 350 GHz. In addition, challenges of new process technologies and materials implementation to improve the device performance will be discussed. copyright The Electrochemical Society.
