Abstract

A semiconductor device has a substrate and a semiconductor package disposed over the substrate. An embedded bar (e-bar) substrate is disposed on the substrate around the semiconductor package. A heat sink is formed over the semiconductor package and supported by the e-bar substrate to elevate the heat sink from the substrate and reduce a thickness of the heat sink. A thermal interface material is deposited between the semiconductor package and heat sink. Alternatively, a shield layer can be formed over the semiconductor package and supported by the e-bar substrate. The e-bar substrate has a base layer and a first metal layer formed over a first surface of the base layer. A bump is formed over the first metal layer. A second metal layer can be over a second surface of the base layer opposite the first surface of the base layer. Two or more e-bar substrates can be stacked.
