Patent ID: 8804358

Claim:
A method for forming an electronic multichip module having at least two electrically interconnected substrates, at least one of the substrates having a deformable metal in a contact region, comprising: providing an insulating liquid curable adhesive over the set of contacts of at least a first of the substrates; aligning respective sets of electrical contacts of the first and a second substrates; compressing the sets of electrical contacts of the first and second substrates to deform the deformable metal and exclude liquid curable adhesive from an intercontact zone; curing the liquid curable adhesive to form a solid matrix while generating a prestress to maintain a compressive force between the respective sets of electrical contacts; maintaining adhesion and mechanical integrity of the cured liquid curable adhesive over at least a range of temperatures between about +50 C to −175 C; and operating a superconducting device on at least one of the electrically interconnected substrates at cryogenic temperatures, wherein the respective sets of electrical contacts are not welded together.
