STACKED TRANSPARENT-DUAL-CHANNEL THIN-FILM TRANSISTOR-BASED PIXELS FOR CMOS IMAGE SENSORS

摘要

A pixel circuit, and method of forming a pixel circuit, an imager device, and a processing system include a photo-conversion device (214), a floating diffusion region (245) for receiving and storing charge from the photo-conversiort device (214), and a transparent transistor (219) for use in operation of the pixel, wherein the transparent transistor (219) is at least partially over the photo-conversion device (214), such that the photo-conversion device (214) receives light passing through the transparent transistor (219).
