  • Patent number: 9524994
    Abstract: An image sensor with an array of pixels is provided. In order to achieve high image quality, it may be desirable to improve well capacity of individual pixels within the array. When forming each pixel, multiple n-type compartments having p-type isolation regions interposed between compartments may be formed. These compartments may have higher dopant concentrations due to lateral depletion that may occur within multiple PN-NP back to back junctions to assist full depletion at pinning-voltage. Compartments may allow distributing a moderately higher electric-field over a larger portion of the photodiode while lowering peak electric-fields that contribute to dark-current. Compartments will thereby improve the well capacity of the photodiode while preventing additional noise that may degrade the quality of the image signal. The quantity, doping, and depth of these compartments may be selected to maximize well capacity while minimizing effects on operating voltage, manufacturing cost, and power consumption.
