Patent ID: 6969640

Claim:
A method for manufacturing an air pocket resistant semiconductor package, comprising: providing a die attached to a substrate; enclosing the die in a heat spreader, the heat spreader having: 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 in the heat spreader extending therethrough; and encapsulating the die, the substrate, at least a portion of the heat spreader, the first encapsulant guide, and the heat spreader air vent in 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, thus preventing the formation of air pockets under the heat spreader.
