Drift Field Implementation in Large Pinned Photodiodes for Improved Charge Transfer Speed
We present a methodology for generating built-in drift fields in large photodiodes. With the aid of TCAD we demonstrate how non-uniform doping profiles can be implemented in a standard CMOS process using a single additional mask and controlled using the implant conditions and mask geometry. We demon...
