Patent ID: 8159825

Claim:
A method for electrically interconnecting two substrates, each having a corresponding set of preformed electrical contacts, at least one of the substrates comprising a functional superconducting electronic circuit, comprising: providing a liquid curable adhesive over the set of contacts of a first substrate, wherein the liquid curable adhesive comprises an adhesive which maintains mechanical integrity down to cryogenic temperatures, has a positive coefficient of thermal expansion when cured, and a viscosity at 20C of less than about 10,000 cp; aligning the set of electrical contacts of the second substrate with the set of electrical contacts of the first substrate; compressing the sets of electrical contacts of the first and second substrates to displace the liquid curable adhesive and provide electrical communication between the respective sets of electrical contacts; and curing the liquid curable adhesive to form a stable solid matrix which maintains a relative compression, and electrical conductivity between, the respective sets of electrical contacts over at least a range of temperatures between about +50C to −175C.
