Patent ID: 8115301

Claim:
An integrated circuit package, comprising: a chip comprising a first surface and an active second surface; a substrate having a first surface and a second surface, wherein the chip is mounted, in a flip-chip manner, onto the substrate such that the active second surface of the chip is facing the first surface of the substrate, and electrical connections are formed between the active second surface of the chip and the first surface of the substrate; a heat-spreader, defining at least one through hole having a side extended across the entire lateral dimension of the chip and the side extended longitudinally parallel to the outline of the chip, coupled to the first surface of the chip and to the first surface of the substrate such that the at least one through-hole is situated within a perimeter of the chip and a gap is defined between the chip and the heat-spreader; and thermal-interface material (TIM) situated within the gap so as to form a thermal connection between the chip and the heat spreader, the thermal-interface material in the at least one of the through hole.
