Title: THIN FILM CRYSTAL WAFER HAVING pn JUNCTION AND ITS MANUFACTURING METHOD
Inventor: FUKUHARA NOBORU
IPC: H01L21/331
Filed: 2002-07-03
Abstract: PROBLEM TO BE SOLVED: To solve the problem concerning carrier depletion in a heterojunction interface between an emitter layer and an emitter cap layer of an HBT. SOLUTION: Between an n-type InGaP layer acting as an emitter layer 7 of the HBT and a GaAs layer 8 formed on the layer 7, a highly doped charge compensation layer 11 is formed, thereby restraining increase of a base current due to depletion phenomenon of carrier in an interface, and preventing decrease of a current amplification factor in a low collector current of the HBT. In order to prevent decrease of a backward withstand voltage between an emitter and a base, which is caused by the amount of n-type impurities introduced for reducing influence of depletion phenomenon being too much, the amount of the n-type impurities is quantitatively adjusted, thereby preventing the decrease of the current amplification factor in the low collector current, while ensuring the backward withstand voltage between the emitter and the base.
