Claim 13:
14. A method of manufacturing an integrated circuit (IC) assembly, the method comprising:
attaching an IC die to a first region of an assembly substrate;
attaching a stiffener to a second region of the assembly substrate, adjacent to the IC die;
applying a continuous layer of thermal interface material (TIM) to a surface of the IC die opposite the assembly substrate, and to a surface of the stiffener opposite the assembly substrate, wherein the TIM comprises a polymer, or a metal including one or more of Au, Ag, In, Bi, Ga, or Sn, or a phase change material (PCM), or graphite, or carbon nanotubes; and
affixing the TIM to maintain direct contact with the surface of the IC die by curing an adhesive between the TIM and the stiffener, or by fusing the TIM directly to the stiffener.
