Abstract
Transferred-substrate HBTs, fabricated with 0.7 micron emitters and 1.6 micron collectors, obtain 277 GHz power-gain cutoff frequencies fmax At 0.1 µm lithography, the device should obtain ~ 500 GHz fmax Deep submicron Schottky-collector resonant tunnel diodes (SRTDs) have estimated 2.2 THz cutoff frequencies. 64-element monolithic SRTD array oscillated at 650 GHz.
