Claim:
1. A method of making an electronic device comprising: forming an interconnect layer stack on a glass substrate and comprising a plurality of patterned electrical conductor layers, and a dielectric layer between adjacent patterned electrical conductor layers, with an uppermost patterned electrical conductor layer including at least one pad; forming a liquid crystal polymer (LCP) substrate and comprising at least one electrical conductor via; aligning the LCP substrate to the interconnect layer stack on a side thereof opposite the glass substrate, with the at least one electrical conductor via being aligned with the at least one pad of the uppermost patterned electrical conductor layer; forming a fused seam directly between the interconnect layer stack and the LCP substrate, and while intermetallically bonding the at least one electrical conductor via to the uppermost patterned electrical conductor layer; and removing the glass substrate.
