Classification: CPC H | IPC H

Claim 18:
19. A method for making a semiconductor device, comprising:
forming a metal layer on a first surface of a semiconductor wafer, the semiconductor wafer having semiconductor dies spaced apart by scribe lanes on a second surface of the semiconductor wafer opposite the first surface, the first surface being a backside of the semiconductor wafer and the second surface being an active surface of the semiconductor wafer;
forming a layer with a modulus greater than 4000 MPa up to 8000 MPa over the metal layer;
mounting the second surface of the semiconductor wafer including the metal layer and the layer on a first side of a dicing tape;
cutting through the semiconductor wafer, the metal layer, and the layer along scribe lanes;
separating the semiconductor dies from the semiconductor wafer and from one another by stretching the dicing tape, expanding the cuts in the semiconductor wafer along the scribe lanes between the semiconductor dies; and
removing the separated semiconductor dies from the dicing tape.
