Abstract

A packaged semiconductor device includes a package substrate, a semiconductor die on the package substrate, an encapsulant over the semiconductor die and package substrate, and a heat spreader having a pedestal portion and an outer portion surrounding the pedestal portion. The encapsulant includes an opening within a perimeter of the semiconductor die. The bottom surface of the pedestal portion of the heat spreader faces the top surface of the semiconductor die, wherein a first portion of the opening and at least a portion of the encapsulant is between the bottom surface of the pedestal portion and the semiconductor die.
