Classification: CPC H | IPC H

Claim 0:
1. A method of forming a semiconductor package, the method comprising:
cutting through a semiconductor assembly that includes a plurality of semiconductor die each including a top side surface comprising a semiconductor material including circuitry therein having bond pads connected to nodes in the circuitry and a bottom side surface, the cutting forming sidewall surfaces defining a sidewall plane that is at an angle from 10° to 60° relative to the bottom side surface, and
forming a metal coating layer including a bottom side metal layer over an entire area of the bottom side surface extending continuously to a sidewall metal layer over the sidewall surfaces, and without extending into the top side surface,
wherein the sidewall metal layer includes the sidewall plane having the angle from 10° to 60°, and wherein the cutting comprises a first cutting step and a second cutting step, the first cutting step utilizing a tapered blade to cut to a middle of the semiconductor assembly, then utilizing a straight shape blade to complete the cutting.
