Abstract

A semiconductor device includes a semiconductor die having a top side surface comprising a semiconductor material including circuitry therein having bond pads connected to nodes in the circuitry, a bottom side surface, and sidewall surfaces between the top side surface and the bottom side surface. A metal coating layer including a bottom side metal layer is over the bottom side surface that extends continuously to a sidewall metal layer on the sidewall surfaces. The sidewall metal layer defines a sidewall plane that is at an angle from 10° to 60° relative to a normal projected from a bottom plane defined by the bottom side metal layer.
