Abstract
A fan-out semiconductor package includes a layer of adhesive covering a temporary carrier, a first redistribution layer disposed on the layer of adhesive, the first redistribution layer including a first metal layer having recessed areas. Metal pillars are plated to a first group of the recessed areas in the first metal layer. A semiconductor chip next is bonded to a second group of the recessed areas and a molding compound covers the semiconductor chip. The molding compound is then ground to expose tops of the metal pillars. A second redistribution layer including a second passivation layer adhering to the molding compound and a second metal layer covering openings exposing the tops of the metal pillars are then added.
