Abstract:
Methods for forming an image sensor structure are provided. The method includes forming a light-sensing region in a substrate and forming a storage node adjacent to light-sensing region in the substrate. The method further includes forming a front side isolation structure partially surrounding an upper portion of the light-sensing region and forming a trench fully surrounding a bottom portion of the light-sensing region to expose a bottom surface of the front side isolations structure. The method further includes forming a backside isolation structure in the trench.

Claim (Index 14):
A method for manufacturing an image sensor structure, comprising:\n forming a light-sensing region in a substrate; forming a first trench from a front side of the substrate, wherein the first trench partially surrounds the light-sensing region; filling a first material in the first trench to form a front side isolation structure; forming a second trench from a backside of the substrate, wherein the second trench fully surrounds the light-sensing region; and filling a second material in the second trench to form a backside isolation structure, wherein the first material is different from the second material and is in direct contact with the second material.
