Claim:
1. A method of manufacturing a package including a plurality of flip chip dies, each flip chip die having a plurality of surfaces, the method comprising: mounting a first surface of a first flip chip die on a substrate; mounting a first surface of a second flip chip die on the substrate; enclosing exposed surfaces of the first flip chip die and exposed surfaces of the second flip chip die with a mold; removing a portion of the mold to expose a second surface of the first flip chip die and a second surface of the second flip chip die, the second surface of the first flip chip die opposite the first surface of the first flip chip die, the second surface of the second flip chip die opposite the first surface of the second flip chip die, and the second surfaces of the first and second flip chip die being inactive surfaces; and after removing the portion of the mold, forming a thermal collection layer on the second surface of the first flip chip die and on the second surface of the second flip chip die, the thermal collection layer substantially matching or exceeding a combined cross sectional area of the first and second flip chip dies, the thermal collection layer configured to dissipate heat generated by the first flip chip die and by the second flip chip die.
