Abstract:
A method of making a multi-layered interconnect structure, comprising:providing a thermally conductive layer including first and second opposing surfaces; positioning a first liquid crystal polymer (LCP) dielectric layer on the first opposing surface of the thermally conductive layer, wherein the first LCP dielectric layer comprises a first LCP dielectric material, and wherein the first LCP dielectric layer includes a first LCP dielectric sublayer positioned on the first opposing surface of the thermally conductive layer; positioning a second LCP dielectric layer on the second opposing surface of the thermally conductive layer, wherein the second LCP dielectric layer comprises a second LCP dielectric material, and wherein the second LCP dielectric layer includes a second LCP dielectric sublayer positioned on the second opposing surface of the thermally conductive layer; and subjecting the first and second LCP dielectric layers to a first and second temperature that are less than the nematic-to-isotropic transition temperature of the first and second LCP dielectric materials, respectively, for a dwell time and at an elevated pressure that is sufficient to cause the first and second LCP dielectric materials to plastically deform and to cause: bonding of the first LCP dielectric sublayer to the thermally conductive layer without any extrinsic adhesive layer disposed between the first LCP dielectric sublayer and the thermally conductive layer, and bonding of the second LCP dielectric sublayer to the thermally conductive layer without any extrinsic adhesive layer disposed between the second LCP dielectric sublayer and the thermally conductive layer.
