Abstract:
A semiconductor package includes a post carrier having a base plate and plurality of conductive posts. A photosensitive encapsulant is deposited over the base plate of the post carrier and around the conductive posts. The photosensitive encapsulant is etched to expose a portion of the base plate of the post carrier. A semiconductor die is mounted to the base plate of the post carrier within the etched portions of the photosensitive encapsulant. A second encapsulant is deposited over the semiconductor die. A first circuit build-up layer is formed over the second encapsulant. The first circuit build-up layer is electrically connected to the conductive posts. The base plate of the post carrier is removed and a second circuit build-up layer is formed over the semiconductor die and the photosensitive encapsulant opposite the first circuit build-up layer. The second circuit build-up layer is electrically connected to the conductive posts.
