Abstract
PURPOSE: To prevent blooming from being generated, by providing a variable transmittivity light transmission layer on the photo detector arrangement face of a semiconductor substrate.
CONSTITUTION: Region 10A of silicon semiconductor substrate 10 having photo detector-forming resion 10A is covered with light transmission-property passivation layer 12 consisting of SiO2 or phosphosilicic acid glass. On this passivation layer 12, variable transmittivevity light transmission layer 14 is formed where the light transmittivity is lowered when the incident light intensity exceeds a prescribed value. As a result, blooming generated by an intensive light incident onto the photo detector can be avoided.
