ABSTRACT:
A lateral heterojunction bipolar transistor (LHBT) comprises emitter and/or collector regions forming a p-n heterojunctions at the emitter/base junction and at the collector/base junction with a planar base region wherein at least the emitter region is formed by employing impurity induced disordering (IID) to produce emitter or collector region of wider bandgap than the base region. The lateral heterojunction bipolar transistor of this invention can also double as a hetero transverse junction (HTJ) laser.
