Abstract

An integrated circuit (IC) package with an embedded heat spreader in a redistribution layer (RDL) is provided. IC packaging facilitates a high density package for ICs, including monolithic microwave integrated circuits (MMICs). However, IC packaging may result in reduced heat removal from an IC, decreasing radio frequency (RF) circuit performance. In an exemplary aspect, an IC package is provided which incorporates an embedded heat spreader within a dielectric layer of an RDL coupled to an IC die. The embedded heat spreader provides efficient heat transfer, robust RF performance, and operation through millimeter wave (mmW) frequencies, all in a miniature low-cost, low-profile surface mountable (SM) package.
