Abstract

Fan-out wafer level packaging includes an integrated circuit having a top surface, a bottom surface, a plurality of side surfaces, and a bond pad defined on the top surface. A layer of encapsulant substantially surrounds the side surfaces of the integrated circuit, the layer of encapsulant having a height substantially equal to a height of the integrated circuit. A bump is spaced apart from the integrated circuit, and a redistribution layer electrically couples the bond pad of the integrated circuit to the bump.
