Title: Superlattice avalanche photodiode and manufacture thereof
Inventor: WATANABE ISAO
IPC: H01L31/107
Filed: 1993-02-04
Abstract: PURPOSE:To improve a low dark current and reliability by embedding mesa formed by etching and removing particular layers with a p<-> type InP or the like, thereby reducing a surface leak dark current. CONSTITUTION:Dangling bond causing an interfacial level or a surface defect is terminated at a p<-> type InP embedded layer 110 which has lattice-matching with a substrate 11, so that these interfacial level and surface defect can be considerably reduced. Also, when recrystalization growth of a semiconductor p<-> type InP embedded layer 110 is in progress at the mesa sidewall, a natural oxide film created on mesa sidewall can be removed by substrate heating or irradiation with a hydrogen radical beam in the molecular beam gaseous phase growth method, so that dangling bond even on a semiconductor natural oxide film or a semiconductor surface can be reduced. Because of this, p<-> type InP layer/interfacial defect on mesa sidewall or interfacial level have been reduced, so that a secular increase can be restricted and a semiconductor photodetector with improved element reliability can be realized.
