Abstract

Disclosed is a CMOS image sensor with global shutters and a method for fabricating the CMOS image sensor. In one embodiment, a semiconductor device, includes: a light-sensing region; a charge-storage region; a light-shielding structure; and at least one via contact; wherein the charge-storage region is spatially configured adjacent to the light-sensing region in a lateral direction, wherein the light-shielding structure is configured over the charge-storage region in a vertical direction so as to prevent incident light leaking from the light-sensing region to the signal-processing region, wherein the light-shielding structure is configured in an interlayer dielectric (ILD) layer, and wherein the light-shielding structure is simultaneously formed with the at least one via contact.
