A semiconductor die, such as a flip-chip die, has a stairstep configuration, which reduces or eliminates the risk of an occurrence of an epoxy on die phenomenon. The stairstep configuration of the semiconductor die is formed during a multi-cut wafer dicing process associated with a semiconductor die fabrication process. During the multi-cut wafer dicing process, a first cutting device, having a first width, forms a first cut in the wafer. The first cut extends partially through the wafer. A second cutting device, having a second width, forms a second cut within the first cut. The combination of the first cut and the second cut form the stairstep configuration of the semiconductor die.
