    摘要: A method includes forming an amorphous carbon layer over a first dielectric layer formed over a substrate, forming a second dielectric layer over the amorphous carbon layer; and forming an opening within the amorphous carbon layer and second dielectric layer by a first etch process to partially expose a top surface of the first dielectric layer. A substantially conformal metal-containing layer is formed over the second dielectric layer and within the opening. The second dielectric layer and a portion of the metal-containing layer are removed. The amorphous carbon layer is removed by an oxygen-containing plasma process to expose a top surface of the first dielectric layer. An insulating layer is formed over the metal-containing layer, and a second metal-containing layer is formed over the insulating layer to form a capacitor.

    摘要: A process for forming backside illuminated devices is disclosed. Specifically, the process reduces processing damage to wafers caused by poor bond quality at the wafer edge ring. In one embodiment, a wafer edge trimming step is implemented prior to bonding the wafer to the substrate. A pre-grind blade is used to create a straight edge around the wafer perimeter, eliminating any sharp edges. In another embodiment, edge trimming is performed after the wafer has been bonded to the substrate, and a pre-grind blade is used to remove portion of the wafer edge ring subject to poor bonding quality before grinding. The final thickness of the ground wafer is about 50 microns in either case.
