Abstract
Structures and methods to improve the crosstalk between adjacent pixels of back-illuminated photodiode arrays on a substrate having first and second surfaces, including providing a first matrix of regions of a first conductivity type of a higher conductivity than the substrate extending into the substrate from the first surface and surrounding each photodiode of the array, and providing a second matrix of regions of a first conductivity type of a higher conductivity than the substrate extending into the substrate from the second surface, the second matrix being a mirror image of and aligned with the first matrix, the matrices extending into the substrate less than one half the thickness of the substrate so as to not touch each other. The methods and corresponding structures may be applied to p/n diodes, pin diodes, avalanche photodiodes, photoconductive cells (no p-n junction at all), or similar photosensitive device arrays.
