Patent ID: 7993941

Claim:
A method of making a semiconductor package, comprising: providing a base plate with a plurality of conductive posts extending from the base plate; disposing a film encapsulant over the base plate and around the conductive posts; mounting a semiconductor die to a carrier; pressing the base plate and carrier together to embed the semiconductor die within the film encapsulant after disposing the film encapsulant over the base plate and around the conductive posts so that the semiconductor die is disposed between the conductive posts in the film encapsulant and the conductive posts extend completely through the film encapsulant; curing the film encapsulant; removing the carrier and base plate; forming a first circuit build-up layer over a first side of the film encapsulant, the first circuit build-up layer being electrically connected to the conductive posts; and forming a second circuit build-up layer over the semiconductor die and a second side of the film encapsulant opposite the first side of the film encapsulant, the second circuit build-up layer being electrically connected to the conductive posts and semiconductor die.
