Abstract
The disclosure provides an image sensor integrated chip and a method for forming the same. The image sensor integrated chip includes a substrate including a pixel region, an isolation structure disposed in the substrate and configured at opposite sides of the pixel region, an image sensing element disposed in the pixel region of the substrate, a gate structure disposed on the pixel region of the substrate, a first dielectric layer disposed above the pixel region of the substrate and covering sidewalls and a portion of a top surface of the gate structure, and a reflective layer disposed on the first dielectric layer. The reflective layer overlaps with the image sensing element and the portion of the top surface of the gate structure in a first direction perpendicular to a surface of the substrate.
