摘要: A method of manufacturing a semiconductor wafer for dicing includes providing a semiconductor wafer including a substrate and a plurality of upper layers on the substrate that form a formation of die areas. The formation is arranged so that adjacent die areas are separated by a path for a dicing tool. Within each path, a pair of spaced apart lines is fabricated. Each line defines a dicing edge of a respective path and has at least one trench extending between a top surface of the wafer and the substrate. Each trench is filled with a stress absorbing material for reducing die tool induced stress on the die areas during dicing.
