Classification: CPC H | IPC H

Claim 15:
16. A manufacturing method of a semiconductor package, comprising:
providing a die package on a substrate, wherein the die package comprises a plurality of semiconductor dies encapsulated by an encapsulating material, the encapsulating material surrounds the plurality of semiconductor die and is disposed between the plurality of semiconductor dies, and upper surfaces of the plurality of semiconductor dies are exposed from the encapsulating material;
attaching a heat dissipation sheet on the die package to cover the upper surfaces of the plurality of semiconductor dies and a top surface of the encapsulating material; and
selectively removing a portion of the heat dissipation sheet covered on the top surface of the encapsulating material to form a plurality of heat dissipation films having a plurality of trenches formed and extended therebetween, the heat dissipation films respectively disposed on and jointly covering the upper surfaces of the plurality of semiconductor dies; and
providing a cover lid on the substrate, wherein the cover lid is in contact with the plurality of heat dissipation films, and a top surface of the encapsulating material faces the cover lid and is exposed from the plurality of trenches.
