ABSTRACT:
A method and apparatus for reducing cross-talk between pixels in a semiconductor based image sensor. The apparatus includes neighboring pixels separated by a homojunction barrier to reduce cross-talk, or the diffusion of electrons from one pixel to another. The homojunction barrier being deep enough in relation to the other pixel structures to ensure that cross-pixel electron diffusion is minimized.
