Claim Text:
1. An apparatus for cooling an integrated circuit (IC) die, comprising: an adhesion layer with high thermal conductivity coated on a surface of the IC die; and a heat dissipation structure comprising one or more sets of heat dissipation plates affixed to the adhesion layer, each plate in the one or more sets having a fin-shaped geometry and oriented such that a largest face of the plate is perpendicular to the surface of the IC die; wherein, for a given set of the heat dissipation plates, a first and a second of the plates in the given set are mechanically coupled through two or more top beams located away from the surface of the IC die and oriented perpendicularly to the largest face of the first and second plates; wherein the second and a third of the plates for the given set are mechanically coupled through two or more bottom beams located near the surface of the IC die and oriented perpendicularly to the largest face of the second and the third plates; and wherein bottom portions of the first and second plates are not mechanically coupled to each other, and top portions of the second and third plates are not mechanically coupled to each other.
