Abstract
A coupler includes a substrate and a stack of first and second dielectric layers extending over a top surface of the substrate. The first dielectric layer comprises different dielectric material than the second dielectric layer. Two conductive lines extend over the stack of first and second dielectric layers, and are formed in the same plane parallel to a surface of the substrate.
