Two epitaxial layers to reduce crosstalk in an image sensor

Two epitaxial layers to reduce crosstalk in an image sensor

An image sensor includes a substrate of a first conductivity type having an image area with a plurality of photosensitive sites, wherein a portion of the charge generated in response to light is collected in the pixel; and a subcollector of a second conductivity spanning the image area that collects...

description An image sensor includes a substrate of a first conductivity type having an image area with a plurality of photosensitive sites, wherein a portion of the charge generated in response to light is collected in the pixel; and a subcollector of a second conductivity spanning the image area that collects another portion of the generated charge that would have otherwise diffused to adjacent photosensitive sites.
