A 0.2-/spl mu/m 180-GHz-f/sub max/ 6.7-ps-ECL SOI/HRS self aligned SEG SiGe HBT/CMOS technology for microwave and high-speed digital applications

A 0.2-/spl mu/m self-aligned selective-epitaxial-growth (SEG) SiGe heterojunction bipolar transistor (HBT)/CMOS technology with high-quality passive elements, made by using SOI on a high-resistivity substrate (SOI/HRS), was developed. The SiGe HBTs exhibited high-frequency, high-speed capability with f/sub max/ of 180 GHz and a fast ECL-gate delay of 6.7 ps.
