Abstract

We demonstrate high-speed InP/InGaAs double-heterojunction bipolar transistors (DHBTs) with significantly improved collector carrier transport. The proposed collector design scheme allows for using moderate collector thickness to achieve high fmax (∼ 300 GHz) while maintaining high fT (∼ 200 GHz). The DHBTs will meet the demand of ultra-high-speed applications for both high fT and high fmax.
