Title: Semiconductor photodetector and its manufacture
Inventor: KATO MASANOBU
IPC: H01L27/14
Filed: 1998-12-10
Abstract: PROBLEM TO BE SOLVED: To increase a photosensitivity of a semiconductor element to increase adhesion by setting an incident angle of light against an insulating film having a specified refractive index and against a slant face so as to get a total internal reflection of light. SOLUTION: In a lower part of an InP substrate 105, a V-shaped groove 113 with a nearly mirror side face 114 is formed, A silicon nitride film 101 as a mirror reflection film is formed in contact with the mirror face 114 of the V-shaped groove 113. Light incident from an end face of the InP substrate 105 is incident into the silicon nitride film 101 at an incident angle θ of 55 deg.. The light incident at an incident angle θ of 55 deg. is totally reflected and then is incident into a light detecting section, with no reduction in the quantity of emitted photons. When the incident angle θ is 40 deg. or above, the silicon nitride film could be replaced with a silicon oxide film as a mirror reflection film. The silicon nitride film and the silicon oxide film have a lower refractive index relative to the InP substrate and have a good adhesion with the InP substrate.
