Abstract:
1. A semiconductor device, comprising: a first integrated circuit (IC) die having a first surface; at least one additional IC die each having a top surface and a bottom surface, the bottom surface of each of the at least one additional IC die being mounted to the first surface of the first IC die; at least one dummy fill each separate from the at least one additional IC die and having a top surface and a bottom surface, the bottom surface of each of the at least one dummy fill being mounted to the first surface of the first IC die adjacent the at least one additional IC die; a heat extraction element extending along and in physical contact with the entire top surface of the at least one additional IC die and the top surface of the at least one dummy fill; and a mounting surface that has direct contact with a bottom surface of the heat extraction element, the mounting surface including the entire top surface of each of the at least one additional IC die and the top surface of the at least one dummy fill, wherein the physical contact of both the entire top surface of the at least one additional IC die and the top surface of the at least one dummy fill enables the thermal coupling of the first IC die to the heat extraction element, wherein the at least one dummy fill provides a direct thermal conductive path from the first IC die to the heat extraction element, and wherein the at least one dummy fill and the at least one additional IC die are encapsulated by a mold compound.
