Patent ID: 7141886

Claim:
An air pocket resistant semiconductor package, comprising: a substrate; a die attached to the substrate; a heat spreader enclosing the die, the heat spreader further comprising: a first encapsulant guide, wherein the first encapsulant guide is located at the center of the heat spreader extending therethrough; a second encapsulant guide positioned on the external surface of the heat spreader, the second encapsulant guide connecting an edge of the heat spreader to the first encapsulant guide; and a heat spreader air vent incorporated in the heat spreader, extending therethrough, and configured for preventing the formation of air pockets under the heat spreader during encapsulation of the die, the substrate, and the heat spreader with an encapsulant such that the encapsulant enters the heat spreader through the first encapsulant guide and air exits the heat spreader through the heat spreader air vent.
