Claim 0:
1. A method comprising:
providing a precursor package including a carrier, a first die attached to a top surface of the carrier, and a first mold compound, which is formed over the top surface of the carrier and encapsulates the first die, wherein the first die comprises a first device layer, a first dielectric layer over the first device layer, and a first die substrate over the first dielectric layer;
thinning down the first mold compound to expose a backside of the first die substrate;
removing substantially the entire first die substrate to create a first opening within the first mold compound and provide a first thinned die, wherein:
a first opening is formed over the first thinned die; and
a top surface of the first thinned die is at a bottom of the first opening;

applying an attach layer directly over the top surface of the first thinned die at the bottom of the first opening after removing the first die substrate; and
inserting at least a portion of a first heat extractor into the first opening after applying the attach layer, such that the first heat extractor is in contact with the attached layer, wherein the first heat extractor is formed of a metal or an alloy.
