Abstract:
1. An electrical inductor comprising: a dielectric layer comprising a liquid crystal polymer (LOP); a first electrically conductive layer of a first metal and on said dielectric layer, said first electrically conductive layer comprising at least one column extending vertically through said dielectric layer and defining terminals; a second electrically conductive layer over said dielectric layer comprising the first metal and defining inductive turns, the first metal comprising copper; and a Cu portions of said second electrically conductive layer not over said at least one column of said first electrically conductive layer being spaced apart from said dielectric layer; the first metal having a melting point temperature greater than that of the second metal; the second metal having a melting point temperature below a lamination temperature of the dielectric layer.
