Patent ID: 6927091

Claim:
A method for fabricating a solid-state imaging device comprising a semiconductor substrate of a first conductivity type, a plurality of light-receiving sections provided at a distance in a surface region of the semiconductor substrate, and channel stop regions of a second conductivity type provided between adjacent light-receiving sections in the surface region and in an internal region of the substrate, the method comprising the steps of: forming a first photoresist layer having openings corresponding to positions at which the channel stop regions are formed; ion-implanting an impurity of a second conductivity type into the semiconductor substrate at a first energy through the first photoresist layer as a mask; forming a second photoresist layer having openings corresponding to positions at which the channel stop regions are formed; and ion-implanting an impurity of a second conductivity type into the semiconductor substrate at a second energy through the second photoresist layer as a mask, wherein the second photoresist layer has a thickness that is smaller than the thickness of the first photoresist layer.
