Classification: CPC H | IPC H

Claim 0:
1. A method for making a semiconductor device, comprising:
forming a metal layer on a surface of a semiconductor wafer, the semiconductor wafer having semiconductor dies spaced apart by scribe lanes, the surface being a backside surface of the semiconductor wafer opposite an active surface;
forming a layer with a modulus of up to 8000 MPa over the metal layer on the surface of the semiconductor wafer;
mounting the surface of the semiconductor wafer including the metal layer and the layer on a first side of a dicing tape;
sawing between the semiconductor dies along the scribe lanes by using a saw blade to cut through the semiconductor wafer, the metal layer, and the layer;
separating the semiconductor dies one from another;
positioning the semiconductor dies on a substrate such that the metal layer and the layer are in between the semiconductor dies and the substrate;
coupling leads of the substrate to bond pads on the semiconductor dies;
covering the semiconductor dies and at least a portion of the leads with mold compound; and
cutting the substrate and the mold compound along saw streets between the semiconductor dies on the substrate, forming separate packaged semiconductor devices, each including at least one semiconductor die.
