Indium phosphide (InP) based double heterojunction bipolar transistors (DHBT) have demonstrated excellent high-speed characteristics. Ultimate performance of digital integrated circuits, however, will depend on aggressively scaled device technologies and appropriate material systems. In this work the high potential of InP based DHBTs with a GaAsSb base is recognized. Guidelines for DHBT device scaling towards 160Gb/s and beyond digital integrated circuits are presented and an InP/GaAsSb/InP DHBT technology based on two-inch substrates is developed. Sub-micron DHBT device scaling is achieved by means of a two-level electron beam lithography (EBL) process. This thesis provides a thorough insight into the design, fabrication and characterization of sub-micron InP/GaAsSb/InP DHBTs as well as the design of ultra high-speed static frequency dividers.
