Abstract

A semiconductor device includes a silicon die having a metal material coating applied on one side, a lead frame having a mounting pad having an area smaller than an area of the silicon die, the silicon die being mounted on the lead frame via the mounting pad, and an etched area filled with a non-conductive mold compound on a side of the lead frame that comes into contact with an end of the silicon die along an edge of the silicon die. A volume of epoxy material is dispensed onto the lead frame along a length of the metal material coating to form a fillet weld on a side of the silicon die configured to adhere the silicon die to the lead frame and to prevent the metal material coating from coming into contact with the lead frame.
