Abstract:
Some embodiments relate to a pixel sensor array including a plurality of photosensors arranged in a semiconductor substrate. A protection ring circumscribes an outer perimeter of the pixel sensor array. The protection ring includes a first ring neighboring the pixel sensor array, a second ring circumscribing the first ring and meeting the first ring at a first p-n junction, and a third ring circumscribing the second ring and meeting the second ring at a second p-n junction. The first ring has a first width, the second ring has a second width, and the third ring has a third width. At least two of the first width, the second width, and the third width are different from one another.

Claim (Index 14):
A device, comprising:\n a semiconductor substrate including a pixel sensor array region; a first plurality of concentric rings of doped semiconductor material disposed in the semiconductor substrate and circumscribing the pixel sensor array region, the first plurality of concentric rings having a first doping type, wherein a first, innermost ring of the first plurality of concentric rings has an inner perimeter in direct contact with an outer perimeter of the pixel sensor array; and at least one ring of doped semiconductor material disposed in the semiconductor substrate and separating two of the first plurality of concentric rings from one another, the at least one ring having a second doping type that is opposite the first doping type.
