ABSTRACT:
A semiconductor chip is formed by dividing a semiconductor wafer by use of the laser dicing technique. The semiconductor chip has a laser dicing region on the side surface thereof. A dummy wiring layer is formed along the laser dicing region on the surface layer of the laser dicing region. A laser beam is applied to the dummy wiring layer to divide the semiconductor wafer.
