IPC: H01L31/107
Filed: 1982-03-31
Abstract: PURPOSE:To form an avalanche photodiode which does not locally break down by doping impurity so that the carrier density of the surface layer is low in the surface and becomes high density deeply toward the interior. CONSTITUTION:InGaAsP is grown as a light absorbing layer 2 on an N<+> type InP1 as a substrate, and an N type InP of a layer is further grown in 2-3mum by vapor phase growth or molecular beam growth on the layer 2. The carrier density of the surface layer 10 formed by InP is not set constantly, for example, as 2X10<16>cm<-3> as the conventional one, but set so that the carrier density is linearly raised toward the depth direction from the surface of the layer 10. Then, a P-N junction 5 which contains a guard ring is formed by the same method as the conventional one, thereby forming a coating layer 6 and a contacting part 7. According to this configuration, a neck 9 is not formed at the periphery of the junction 5 and hence at the bent part of the guard ring 8, and the curvature of the curved part 11 can be increased from the relationship between the impurity density of the linear grade junction and the junction position.
