Abstract:
The invention is directed to an improved semiconductor chip that reduces crack initiation and propagation into the active area of a semiconductor chip. A semiconductor wafer includes dicing channels that separate semiconductor chips and holes through a portion of a semiconductor chip, which are located at the intersection of the dicing channels. Once diced from the semiconductor wafer, semiconductor chips are created without ninety degree angle corners.
