Abstract

A semiconductor package structure is provided, including: a semiconductor chip having electrode pads disposed thereon and metal bumps disposed on the electrode pads; an encapsulant encapsulating the semiconductor chip; a dielectric layer formed on the encapsulant and having a plurality of patterned intaglios formed therein for exposing the metal bumps; a wiring layer formed in the patterned intaglios of the dielectric layer and electrically connected to the metal bumps; and a metal foil having a plurality of metal posts disposed on a surface thereof such that the metal foil is disposed on the encapsulant with the metal posts penetrating the encapsulant so as to extend to the inactive surface of the semiconductor chip. Compared with the prior art, the present invention reduces the overall thickness of the package structure, increases the electrical transmission efficiency and improves the heat dissipating effect.
