The present invention generally is a method for forming a high-k
dielectric layer, comprising depositing a hafnium compound by atomic
layer deposition to a substrate, comprising, delivering a hafnium
precursor to a surface of the substrate, reacting the hafnium precursor
and forming a hafnium containing layer to the surface, delivering a
nitrogen precursor to the hafnium containing layer, forming at least one
hafnium nitrogen bond and depositing the hafnium compound to the surface.
