Methods for forming metal silicate films are provided. The methods comprise contacting a substrate with alternating and sequential vapor phase pulses of a silicon source chemical, metal source chemical, and an oxidizing agent, wherein the metal source chemical is the next reactant provided after the silicon source chemical. Methods according to some embodiments can be used to form silicon-rich hafnium silicate and zirconium silicate films with substantially uniform film coverages on substrate surface.
