Abstract
A liquid cooled semiconductor device is provided. The device includes a semiconductor die and a heat spreader. In one aspect of the invention, the heat spreader is mounted to a substrate such that a first side of the spreader is exposed on one side of the substrate and that a second side of the heat spreader is exposed on an opposing side of the substrate. Attached to a first side of the spreader is the semiconductor die. In another aspect of the invention, a wetting material is used to provide a thermal/electrical connection between the die and heat spreader. Sealant is provided between the die and the heat spreader to encapsulate and contain the wetting material.
