Method of forming a substrate with interposer channels for cooling the substrate
First Claim
1. A method of forming a structure, said method comprising:
- providing a substrate, said substrate comprising N continuous substrate channels on a first side of the substrate, said substrate having a heat source therein, said N being at least 2;
providing an interposer, said interposer comprising N continuous interposer channels;
coupling the N interposer channels to the N substrate channels so as to form M continuous loops such that 1≦
M≦
N, each loop of the M loops independently consisting of K substrate channels of the N substrate channels and K interposer channels of the N interposer channels in an alternating sequence of substrate channels and interposer channels, for each loop of the M loops said K is at least 1 and is subject to an upper limit consistent with a constraint of having the M loops collectively consist of the N interposer channels and the N substrate channels, each loop of the M loops independently being open ended or closed, said first side of the substrate being connected to the interposer, said interposer adapted to be thermally coupled to a heat sink such that the interposer is interposed between the substrate and the heat sink.

Abstract
A method of forming structure. A substrate and an interposer are provided. The substrate includes a heat source and N continuous substrate channels on a first side of the substrate (N≧2). N interposer channels are coupled to the N substrate channels so as to form M continuous loops (1≦M≦N). Each loop independently consists of K substrate channels and K interposer channels in an alternating sequence. For each loop, K is at least 1 and is subject to an upper limit consistent with a constraint of the M loops collectively consisting of the N interposer channels and the N substrate channels. Each loop is independently open ended or closed. The first side of the substrate is connected to the interposer. The interposer is adapted to be thermally coupled to a heat sink such that the interposer is interposed between the substrate and the heat sink.
