Abstract

A method of forming a metal oxide dielectric film. According to the present invention an amorphous metal oxide dielectric film is deposited over a substrate utilizing a metal organic precursor. The substrate is then heated in an inert ambient to convert the amorphous metal oxide dielectric to a polycrystalline metal oxide dielectric. The polycrystalline metal dielectric is then heated in a oxygen containing ambients.
