摘要:
Provided is a high ruggedness heterojunction bipolar transistor (HBT), including a substrate, a sub-collector layer, collector layer, a base layer, and an emitter layer. The collector layer includes a InGaP layer or a wide bandgap layer. The collector layer includes III-V semiconductor material. The bandgap of the wide bandgap layer is greater than that of GaAs.
