Abstract
Provided are methods of depositing hafnium or zirconium containing metal alloy films. Certain methods comprise sequentially exposing a substrate surface to alternating flows of an organometallic precursor and a reductant comprising M(BH)to produce a metal alloy film on the substrate surface, wherein M is selected from hafnium and zirconium, and the organometallic precursor contains a metal N. Gate stacks are described comprising a copper barrier layer comprising boron, a first metal M selected from Hf and Zr, and a second metal N selected from tantalum, tungsten, copper, ruthenium, rhodium, cobalt and nickel; and a copper layer overlying the copper barrier seed layer.
