Abstract:
A fabrication method for producing semiconductor chips with enhanced die strength comprises following steps: forming a semiconductor wafer with enhanced die strength by comprising the substrate, the active layer on the front side of the substrate and the backside metal layer on the backside of the substrate, wherein at least one integrated circuit forms in the active layer; forming a protection layer on a front side of the semiconductor wafer; dicing the semiconductor wafer by at least one laser dicing process and removing the laser dicing residues and removing said protection layer by at least one etching process, whereby plural semiconductor chips with enhanced die strength are produced, and wherein the backside metal layer of said semiconductor chip fully covers the backside of said semiconductor chip after dicing.
