Title: Heterojunction bipolar transistor
Inventor: HARA YOSHIHIRO
IPC: H01L29/73
Filed: 1998-07-16
Abstract: PROBLEM TO BE SOLVED: To improve the characteristics of a heterojunction bipolar transistor where the laser layer comprises a mixed crystal having graded composition. SOLUTION: An emitter layer and a collector layer comprise Si and a base layer comprises a mixed crystal of Si and Ge. Composition rate of Ge in the base layer increases gradually (inclines) from 8% to 20% from the emitter side toward the collector side. Concentration of B in the base layer decreases gradually (inclines) from 1×1019 to 1×1018 cm-3 from the emitter side toward the collector side. Since a sufficient inclination can be ensured at the band end of a conduction band in the base layer even if the inclination of the composition rate of Ge is made gentle in the base layer, variation rate in the composition of mixed crystal can be reduced while keeping a short carrier traveling time by high field intensity of the base layer. Consequently, current amplification factor βmax can be enhanced.
