Abstract

A semiconductor device having a plated heat sink (PHS) layer on the back surface, preventing a short circuit between a bonding wire, and a first metal layer. A method of making a semiconductor device including forming a catalyst layer on a bottom of a first separation groove in the front surface of a semiconductor substrate, and forming the first metal layer selectively in the first separation groove by electroless plating, using the catalyst layer as a catalyst.
