Patent ID: 7059049

Claim:
A method of making a multi-layered interconnect structure, comprising the steps of: providing a thermally conductive layer including first and second opposing surfaces; laminating a first dielectric layer on said first opposing surface of said thermally conductive layer such that the first dielectric layer includes a first dielectric material, said laminating occurring at a pressure between a minimum pressure of about P 1MIN and a maximum pressure of about P 1MAX and at a temperature between a minimum temperature of about T 1MIN and a maximum temperature of about T 1MAX , wherein T 1MAX constrains a ductility of the first dielectric layer to be at least about D 1 following said laminating, and wherein T 1MAX depends on D 1 and on the first dielectric material; and laminating a second dielectric layer on said second opposing surface of said thermally conductive layer such that the second dielectric layer includes a second dielectric material, said laminating occurring at a pressure between a minimum pressure of about P 2MIN and a maximum pressure of about P 2MAX and at a temperature between a minimum temperature of about T 2MIN and a maximum temperature of about T 2MAX , wherein T 2MAX constrains a ductility of the second dielectric layer to be at least about D 2 following said laminating, and wherein T 2MAX depends on D 2 and on the second dielectric material.
