Abstract
A semiconductor package includes a substrate, a stiffener ring coupled to the substrate and configured to form a well with the substrate, and a die positioned in the well. A thermal interface is positioned on the die. A heat spreader is coupled to the stiffener ring so that a portion of the heat spreader is positioned in the well and the thermal interface thermally couples the heat spreader to the die. The portion of the heat spreader positioned in the well adds rigidity to the semiconductor package and facilitates the use of thin dies.
