Abstract: A flip chip ball grid array package includes a package substrate and a flip chip device mounted on a top surface of the package substrate. The flip chip device includes a semiconductor integrated circuit die; an epoxy molding compound encapsulating vertical sidewalls of the semiconductor integrated circuit die; a re-distribution layer structure disposed on an active surface of the semiconductor integrated circuit die and on a lower surface of the epoxy molding compound; a sintered nanosilver layer disposed on a passive rear surface of the semiconductor integrated circuit die and on an upper surface of the epoxy molding compound; and a stiffener ring mounted around the flip chip device on the package substrate.

Abstract: A semiconductor package includes a substrate having a top surface and a bottom surface. A semiconductor device is mounted on the top surface of the substrate. The semiconductor device has an active front surface directly facing the substrate, and an opposite rear surface. A vapor chamber lid is in thermal contact with the rear surface of the semiconductor device. The vapor chamber lid includes an internal vacuum-sealed cavity that stores a working fluid, and wick structures for recirculating the working fluid within the internal vacuum-sealed cavity.
