英文摘要 | With a crystal orientation dependent on the etch rate of si in koh-based solution, a base-emitter self-aligned large-area multi-linger configuration power sige heterojunction bipolar transistor (hbt) device (with an emitter area of about 880 mu m(2)) is fabricated with 2 mu m double-mesa technology. the maximum dc current gain is 226.1. the collector-emitter junction breakdown voltage bvceo is 10 v and the collector-base junction breakdown voltage bvcbo is 16 v with collector doping concentration of 1 x 10(17) cm(-3) and thickness of 400 nm. the device exhibited a maximum oscillation frequency f(max) of 35.5 ghz and a cut-off frequency f(t) of 24.9 ghz at a dc bias point of i-c = 70 ma and the voltage between collector and emitter is v-ce = 3 v. load pull measurements in class-a operation of the sige hbt are performed at 1.9 ghz with input power ranging from 0 dbm to 21 dbm. a maximum output power of 29.9 dbm (about 977 mw) is obtained at an input power of 18.5 dbm with a gain of 11.47 db. compared to a non-self-aligned sige hbt with the same heterostructure and process, f(max) and f(t) are improved by about 83.9% and 38.3%, respectively. |
