Abstract:
1. A method for forming a semiconductor device, the method comprising: providing a device substrate having a frontside and a backside defined thereupon, the backside opposite the frontside, the device substrate further having a plurality of pixels formed at the frontside; forming a color filter layer and one or more microlenses on the backside of the device substrate; forming a dam structure on the backside of the device substrate; coupling a backside substrate to the dam structure, wherein the backside substrate is coupled to the dam structure to define a cavity surrounding the color filter layer and the one or more microlenses; prior to the forming of the color filter layer and the one or more microlenses and prior to the forming of the dam structure: forming a redistribution layer disposed over and electrically coupled to the interconnect structure; wherein the forming of the redistribution layer is performed prior to the coupling of the glass substrate, and wherein the coupling of the glass substrate releasably couples the glass substrate to the redistribution layer.
