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 7):
A method for manufacturing an image sensor structure, comprising:\n forming a light-sensing region in a substrate; forming a storage node adjacent to the light-sensing region; forming a first trench partially surrounding an upper portion of the light- sensing region in the substrate; forming a front side isolation structure in the first trench; forming a second trench surrounding a bottom portion of the light-sensing region and partially overlaps with the storage node in the substrate; and forming a backside isolation in the second trench.
