Abstract:
A method of fabricating a semiconductor stacked package is provided. A singulation process is performed on a wafer and a substrate, on which the wafer is stacked. A portion of the wafer on a cutting region is removed, to form a stress concentrated region on an edge of a chip of the wafer. The wafer and the substrate are then cut, and a stress is forced to be concentrated on the edge of the chip of the wafer. As a result, the edge of the chip is warpaged. Therefore, the stress is prevented from extending to the inside of the chip. A semiconductor stacked package is also provided.
