Title: Epitaxial wafer for hetero junction bipolar transistor, and hetero junction bipolar transistor
Inventor: KAMOGAWA HIROYUKI
IPC: H01L21/331
Filed: 2000-05-22
Abstract: PROBLEM TO BE SOLVED: To provide an epitaxial wafer for hetero junction bipolar transistor with high β and reliability. SOLUTION: Se is used as the dopant of a collector contact layer 11, and Si is used as the dopant of a collector layer 12, thus preventing the propagation of a crystal defect that a wafer has before an epitaxial layer grows. Also, the same carrier concentration can be obtained by the doping lower carrier concentration than Si doping, thus contributing to the reduction of the crystal defect of a collector contact layer itself and obtaining a higher β than Si-doped HBT. Also, the decrease in the crystal defect also contributes to the reliability in HBT, thus increasing life. Also, the collector layer 12 reduces the diffusion of a dopant into a base layer 5 and improves reliability by using Si as the dopant as before.
