A metal oxynitride layer formed by atomic layer deposition of a plurality of reacted monolayers, the monolayers comprising at least one each of a metal, an oxide and a nitride. The metal oxynitride layer is formed from zirconium oxynitride, hafnium oxynitride, tantalum oxynitride, or mixtures thereof. The metal oxynitride layer is used in gate dielectrics as a replacement material for silicon dioxide. A semiconductor device structure having a gate dielectric formed from a metal oxynitride layer is also disclosed.
