Abstract

A Quad Flat Non-leaded (QFN) semiconductor package has a semiconductor die mounted on a die flag of a lead frame. A molded housing with a base and sides covers the die. The package has electrically conductive mounting feet each of which includes an exposed base surface in the base of the housing, an opposite parallel surface covered by the housing, and an exposed end surface in the one of the sides of the housing. The exposed end surface is normal to, and located between, the exposed base surface and the opposite parallel surface. Bond wires selectively electrically connect electrodes of the die to respective ones of the mounting feet. An electrically conductive plating coats the exposed base portion and exposed end surface of the mounting feet.
