  • Publication number: 20140252628
    Abstract: A method for forming a semiconductor interconnect structure comprises forming a dielectric layer on a substrate and patterning the dielectric layer to form an opening therein. The opening is filled and the dielectric layer is covered with a metal layer having a first etch rate. The metal layer is thereafter planarized so that the metal layer is co-planar with the top of the dielectric layer. The metal layer is annealed to change the first etch rate into a second etch rate, the second etch rate being lower than the first etch rate. A copper-containing layer is formed over the annealed metal layer and the dielectric layer. The copper-containing layer has an etch rate greater than the second etch rate of the annealed metal layer. The copper-containing layer is etched to form interconnect features, wherein the etching stops at the top of the annealed metal layer and does not etch thereunder.
