  • Abstract
    Using a combination of wet and dry chemical treatments, the parasitic surface current between the base and emitter of AlGaAs/GaAs heterojunction bipolar transistors (HBTs) has been suppressed by more than two orders of magnitude. This treatment opens up a variety of applications over a wide range of collector currents for selfaligned microwave AlGaAs/GaAs HBTs.
