Abstract

A semiconductor device includes a substrate including traces, wherein the traces protrude above a top surface of the substrate; a prefill material over the substrate and between the traces, wherein the prefill material directly contacts peripheral surfaces of the traces; a die attached over the substrate; and a wafer-level underfill between the prefill material and the die.
