AlGaAs/GaAs HBT with GaInAs cap layer fabricated by multiple-self-alignment process using one mask

Abstract
An AlGaAs/GaAs HBT has been fabricated by introducing an n+-GaInAs cap layer to reduce the emitter contact resistivity and optimising a multiple self-alignment process using one mask. The HBT has a good high-frequency performance of fT= 82GHz and fmax= 120GHz
