Cooling of substrate using interposer channels
First Claim
1. A method of forming a structure, said method comprising forming an interposer adapted to be interposed between a heat source and a heat sink and to transfer heat from the heat source to the heat sink, said interposer comprising an enclosure that encloses a cavity, said enclosure being made of a thermally conductive material, said cavity comprising a thermally conductive foam material therein, said foam material comprising pores and comprising at least one serpentine channel, each serpentine channel having a plurality of contiguously connected channel segments, each serpentine channel independently forming a closed loop or an open ended loop, said foam material adapted to be soaked by a liquid filling said pores, each serpentine channel being adapted to be partially filled with a fluid that serves to transfer heat from the heat source to the heat sink.

Abstract
A method of forming a structure. An interposer is provided. The interposer is adapted to be interposed between a heat source and a heat sink and to transfer heat from the heat source to the heat sink. The interposer includes an enclosure that encloses a cavity. The enclosure is made of a thermally conductive material. The cavity includes a thermally conductive foam material. The foam material includes pores and includes at least one serpentine channel. Each serpentine channel has at least two contiguously connected channel segments. Each serpentine channel independently forms a closed loop or an open ended loop. The foam material is adapted to be soaked by a liquid filling the pores. Each serpentine channel is adapted to be partially filled with a fluid that serves to transfer heat from the heat source to the heat sink.
