Pixel Isolation Elements, Devices and Associated Methods

摘要

Light trapping pixels, devices incorporating such pixels, and various associated methods are provided. In one aspect, for example, a light trapping pixel device can include a light sensitive pixel having a light incident surface, a backside surface opposite the light incident surface, and a peripheral sidewall disposed into at least a portion of the pixel and extending at least substantially around the pixel periphery. The pixel can also include a backside light trapping material substantially covering the backside surface and a peripheral light trapping material substantially covering the peripheral sidewall. The light contacting the backside light trapping material or the peripheral light trapping material is thus reflected back toward the pixel.

主权项

1. A light trapping device, comprising:
at least one light sensitive pixel having a light incident surface, a backside surface opposite the light incident surface, and a peripheral sidewall disposed into at least a portion of the pixel and extending at least substantially around the pixel periphery; a backside light trapping material substantially covering the backside surface; and a peripheral light trapping material substantially covering the peripheral sidewall,wherein light contacting the backside light trapping material or the peripheral light trapping material is reflected back toward the pixel.
