Abstract

A method of forming a semiconductor device includes attaching a metal foil to a carrier, the metal foil being pre-made prior to attaching the metal foil; forming a conductive pillar on a first side of the metal foil distal the carrier; attaching a semiconductor die to the first side of the metal foil; forming a molding material around the semiconductor die and the conductive pillar; and forming a redistribution structure over the molding material.
