Filed: 1986-03-18
Abstract: PURPOSE:To obtain a hetero junction bipolar transistor suitable for a high speed and high power element by forming a collector and a base layer of semiconductor layers, forming a beta-silicon carbide layer having larger forbidden band width than the semiconductor layer thereon, and using the layer as an emitter. CONSTITUTION:The other conductivity type semiconductor layer 2 and one conductivity type beta-silicon carbide layer 3 are sequentially grown on one conductivity type semiconductor layer 1, the layer 1 is used as a collector region, the layer 2 is used as a base region and the layer 3 is used as an emitter region. In order to form a wide gap emitter layer, beta-SiC of the same crystal as Si is used. SiC crystal growth generally requires high temperature growth to be difficult, but single crystal SiC is vapor grown at approx. 1,000 deg.C under reduced pressure of approx. 200Pa. The Hall easiness of the single crystal SiC has the same as Si or larger, rectification ratio of SiC/Si hetero junctions is large, and a diffusing current mainly flows to a junction. Thus, a high speed bipolar transistor adapted to a VLSI having high emitter efficiency is obtained.
