Patent ID: 8399056

Claim:
A method of forming on at least one substrate at least one metal containing dielectric film having the formula (M 1 1-a M 2 a ) O b N c , wherein: 0≦a<1 0<b≦3, 0≦c≦1, M 1 being a metal and M 2 being selected from the group consisting of Mg, Ca, Zn, B, Al, In, Lanthanides, Si, Ge, Sn, Ti, Zr, Hf, V, Nb, and Ta; said method comprising the steps of: (a) providing a substrate into a reactor; (b) introducing into said reactor at least one metal containing precursor selected from the group consisting of Hf(MeCp) 2 Me 2 , HfCp(MeCp)Cl 2 , Hf(MeCp) 2 Cl 2 , HfCp(MeCp)Me 2 , Hf(EtCp)(MeCp)Me 2 , Hf(MeCp) 2 (CO) 2 , Zr(MeCp) 2 Cl 2 , ZrCp(MeCp)Me 2 , Zr(EtCp)(MeCp)Me 2 , Zr(EtCp) 2 Me 2 , Zr(MeCp) 2 (CO) 2 and mixtures thereof; (c) optionally introducing at least one M 2 containing precursor, M 2 being selected from the group consisting of Mg, Ca, Zn, B, Al, In, Lanthanides, Si, Ge, Sn, Ti, Zr, Hf, V, Nb, and Ta; (d) providing at least one oxygen containing and/or nitrogen containing fluid into said reactor; (e) reacting said at least one metal containing precursor with said at least one oxygen containing and/or nitrogen containing fluid; and (f) depositing said (M 1 1-a M 2 a ) O b N c film onto said substrate at a temperature comprised between 100 to 500° C.
