Patent JP-H1027922-A (JP)
Title: Manufacture of optical sensor
Inventor: INOUE KEIJIROU
IPC: H01L31/10
Filed: 1996-07-11
Abstract: PROBLEM TO BE SOLVED: To provide an integrated circuit having a photoelectric converter which can set a thickness of an oxide film formed on a light receiving part of the photoelectric converter so as to provide a small variation for its light transmission factor and to improve light reception characteristics, even when the oxide film varies in its thickness. SOLUTION: Oxide films 17b and 18 are formed on a light receiving part of a photodiode 3 formed on a silicon substrate 1. In this case, the oxide films 17b and 18 are formed on the basis of an oxide-film-thickness characteristic curve of the light receiving part representing a relationship between a light transmission factor on the surface of the light receiving part and the thicknesses of the oxide films 17b and 18. However, since the light transmission factor remarkably changes in the vicinity of a first peak film thickness on the character curve providing a maximum light transmission factor the formation of the oxide films 17b and 18 is carried out, based on another peak film thickness other than the first peak as a target.
