Pin diode detector, method of making the same, and system including the same

A method of making a PIN diode detector, the method comprising:

• implanting a plurality of PIN diode wells into a pixel region of a substrate, wherein each of the plurality of PIN diode wells has a first dopant type;
• implanting a plurality of ring wells into a peripheral region of the substrate, wherein the peripheral region surrounds the pixel region, a first ring well of the plurality of ring wells has the first dopant type, and a second ring well of the plurality of ring wells has a second dopant type opposite the first dopant type;
• and
• blanket doping the pixel region and the peripheral region of the substrate to define a blanket doped region continuous across the pixel region and the peripheral region, wherein the blanket doped region has the second dopant type.

A PIN diode detector system, the system comprising:

• a PIN diode detector configured to detect electromagnetic radiation, wherein the PIN diode detector comprises:
• a substrate, wherein the substrate includes a pixel region and a peripheral region, and the peripheral region surrounds the pixel region;
• a plurality of PIN diode wells in the pixel region, wherein each of the plurality of PIN diode wells has a first dopant type;
• a plurality of ring wells in the peripheral region, wherein at least one ring well of the plurality of ring wells has a different dopant type from another ring well of the plurality of ring wells;
• and
• a blanket doped region, wherein 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;
• and
• a display configured to display an image corresponding to the detected electromagnetic radiation.
