Abstract:
1. A packaging method for a circuit die comprising: encapsulating a circuit component with molding material, the circuit component comprising a circuit die, an inner surface of a top mold plate used for containing the molding material during encapsulation being spaced vertically from a top surface of the circuit component during the encapsulating step so that the molding material forms a continuous top surface that covers and fully encapsulates the circuit component and at least a portion of a top surface of a substrate on which the circuit component is disposed; removing at least a portion of the molding material over the circuit die to create a recessed region within the molding material; and disposing a heat spreader over the recessed region of the molding material, a bottom surface of the heat spreader having a first downset disposed within the recessed region while a remainder of the bottom surface of the heat spreader is aligned with a top surface of the molding material, a top surface of the heat spreader having a second downset disposed over and aligned with at least a portion of the recessed region.
