Abstract
A method includes forming and patterning a first dielectric over a substrate; covering the first dielectric with metal and planarizing the metal exposing a surface of the first dielectric and forming a first metal; forming a second dielectric over the first dielectric and the first metal; covering the second dielectric with metal and planarizing the metal exposing a surface of the second dielectric and forming a second metal; forming a mask over the second dielectric and the second metal; and transferring: a first sub-pattern of the mask into a first portion of the first metal to form a lower metal, a second sub-pattern of the mask into a first portion of the second metal and a second portion of the first metal to form a stacked metal, and a third sub-pattern of the mask into a second portion of the second metal to form an upper metal.
