ABSTRACT:
A hetero-junction type bipolar transistor has an SiGe layer as a base layer and an SiC layer as an emitter layer. Between the SiGe layer and the SiC layer of the hetero-junction bipolar transistor, a monocrystalline layer having a lattice constant between the lattice constant of SiGe and that of SiC.
