An atomic layer deposition method to deposit an oxide nanolaminate thin
film is provided. The method employs a nitrate ligand in a first
precursor as an oxidizer for a second precursor to form the oxide
nanolaminates. Using a hafnium nitrate precursor and an aluminum
precursor, the method is well suited for the deposition of a high k
hafnium oxide/aluminum oxide nanolaminate dielectric for gate dielectric
or capacitor dielectric applications on a hydrogen-terminated silicon
surface.
