Abstract

Processing methods for depositing aluminum etch stop layers comprise positioning a substrate within a processing chamber, wherein the substrate comprises a metal surface and a dielectric surface; exposing the substrate to an aluminum precursor gas comprising an isopropoxide based aluminum precursor to selectively form an aluminum oxide (AlOx) etch stop layer onto the metal surface while leaving exposed the dielectric surface during a chemical vapor deposition process. The metal surfaces may be copper, cobalt, or tungsten.
