Abstract
A crosstalk-suppressing image sensor includes a semiconductor substrate, an opaque layer, and a spectral filter. The semiconductor substrate includes a photodiode therein and is located beneath a light-exposure region of a back surface of the semiconductor substrate. The opaque layer is on the back surface, partially covers the light-exposure region, and has an opaque-layer thickness perpendicular to an image-plane direction parallel to the back surface. The spectral filter is adjacent to the opaque layer in the image-plane direction, and partially covers the light-exposure region.
