    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.

    摘要: A semiconductor structure includes a substrate, a first III-V compound layer over the substrate, one or more sets of III-V compound layers over the first III-V compound layer, a second III-V compound layer over the one or more sets of III-V compound layers, and an active layer over the second III-V compound layer. The first III-V compound layer has a first type doping. Each of the one or more sets of III-V compound layers includes a lower III-V compound layer and an upper III-V compound layer over the lower III-V compound layer. The upper III-V compound layer having the first type doping, and the lower III-V compound layer is at least one of undoped, unintentionally doped having a second type doping, or doped having the second type doping. The second III-V compound layer is either undoped or unintentionally doped having the second type doping.
