Abstract: Interconnect structures and methods of formation of such interconnect structures are provided herein. In some embodiments, a method of forming an interconnect includes: depositing a silicon-aluminum oxynitride (SiAlON) layer atop a first layer of a substrate, wherein the first layer comprises a first feature filled with a first conductive material; depositing a dielectric layer over the silicon-aluminum oxynitride (SiAlON) layer; and forming a second feature in the dielectric layer and the silicon-aluminum oxynitride (SiAlON) layer to expose the first conductive material.
