Patterning a layered chrome-copper structure disposed on a dielectric substrate

Abstract

An electrical structure, comprising a first dielectric layer, a patterned layer on the first dielectric layer, and a second dielectric layer on the patterned layer. The patterned layer includes a metal pattern on the first dielectric layer, a metallic pattern on the metal pattern, and a plugged pattern within a remaining space of the patterned layer. The plugged pattern includes a dielectric material. The second dielectric layer is adhesively bonded to a top surface of the patterned layer. The second dielectric layer includes the dielectric material.
