Title: TRANSPARENT-CHANNEL THIN-FILM TRANSISTOR-BASED PIXELS FOR HIGH-PERFORMANCE IMAGE SENSORS[err](57) Abstract: A pixel circuit, and method of forming a pixel circuit, an imager device, and a processing system include a photo-conversion device, a floating diffusion region for receiving and storing charge from the photo-conversiort device, and a transparent N transistor for use in operation of the pixel, wherein the transparent transistor is at least partially over the photo-conversion device, such that the photo-conversion device receives light passing through the transparent transistor.
