Abstract
An image sensor with a plurality of photodiodes pixels. At least one of the photodiodes pixels includes a reflective element that prevents light from traveling onto an adjacent photodiode pixel. The reflective element may be a floating contact adjacent a routing wire of the image sensor. The reflective element may have an aspect ratio that maximizes the reflective surface of the element.
Claims20
An image sensor, comprising:
- a photodiode array that includes a plurality of photodiode pixels, at least one of said photodiode pixels includes;
- a photo-absorption region;
- a wire;
- a reflective element that is adjacent said wire and reflects light onto said photo-absorption region.
