Patent ID: 7882624

Claim:
A method comprising: forming a fluid-conducting channel in a package element of an integrated circuit package to couple to an upper surface of a die, wherein the die has a geometry of a first size, wherein the channel has a geometry of a second size greater than the first size; forming at least one O-shaped core element to overlap a portion of the channel not overlapped by the die, wherein the core element is laterally adjacent to and surrounds the die, and wherein the core element has an upper surface co-extensive with the upper surface of the die and coupled to the package element; coupling a thin thermal interface material to the package element; coupling the die to the thin thermal interface material; wherein forming the fluid-conducting channel includes: forming the channel in a surface of the package element; filling the channel with a filler material; after filling, polishing the surface of the package element; and after coupling the die to the thermal interface material, removing the filler material.
