Abstract:
Apparatus for depositing and enhancing a nitride film on a semiconductor wafer comprising:a process chamber;a showerhead positioned within said process chamber;a gas source connected to said showerhead, said gas source comprising a nitride film-forming process gas containing a metallo-organic precursor and an oxidation gas;a wafer support positioned within said process chamber;a heater positioned proximate said wafer support, wherein said heater supplies sufficient energy to said wafer support to decompose said metallo-organic precursor and deposit said nitride film;a first RF source coupled to said showerhead; anda second RF source coupled to said wafer support, wherein said first and second RF sources couple RF energy respectively to said showerhead and said wafer support to produce an oxidation plasma from said oxidation gas, whereby said deposited nitride film is oxidized within said process chamber.
