Abstract
A PIN diode detector includes a substrate. The PIN diode detector further includes a plurality of PIN diode wells in a pixel region, wherein each of the plurality of PIN diode wells has a first dopant type. The PIN diode detector further includes a connecting ring well and a plurality of floating ring wells in a peripheral region, wherein the connecting ring well and plurality of floating ring wells have the first dopant type. The PIN diode detector further includes a field stop ring well surrounding the plurality of floating ring wells, wherein the field stop ring well has a second dopant type opposite the first dopant type. The PIN diode detector further includes a blanket doped region. The blanket doped region extends continuously through an entirety of the pixel region and an entirety of the peripheral region, and the blanket doped region has the second dopant type.
