Patent ID: 8454928

Claim:
A process for depositing a tellurium-containing film on a substrate, comprising: (a) providing a substrate in a reactor configured for chemical vapor deposition or for atomic layer deposition; (b) introducing into the reactor at least one tellurium-containing precursor selected from the group consisting of: Me 2 Te=NtBu; Me 2 Te(-NtBu-) 2 TeMe 2 ; Te(NiPr-CiPr—NiPr) 2 ; MeTe(NiPr-CiPr—NiPr); MeTe(NiPr—C(—NMe 2 )-NiPr); Te(MeN—CH 2 —CH 2 —NMe 2 ); TeMe(MeN—CH 2 —CH 2 —NMe 2 ); Te(EtN—CH 2 —CH 2 —NMe 2 ); TeMe(EtN—CH 2 —CH 2 —NMe 2 ); Te(MeN—CMe 2 —CH 2 —NMe 2 ); TeMe(MeN—CMe 2 -CH 2 —NMe 2 ); Te(MeN—CH 2 —CH 2 —OMe); TeMe(MeN—CH 2 —CH 2 —OMe); (tBuN═)Te(-NtBu-) 2 Te(=NtBu); and (iPrN═)Te(-NiPr-) 2 Te(=NiPr); (c) optionally, introducing at least one M-containing source, wherein M is Si, Ge, Sb, Sn, Pb, Bi, In, Ag or Se, or a combination of any of those, into said reactor; (d) optionally, introducing a hydrogen-containing fluid into the reactor; (e) optionally, introducing an oxygen-containing fluid into the reactor; (f) optionally, introducing a nitrogen-containing fluid into the reactor; (g) reacting the precursor(s) and M-containing source(s), if any, in the reactor with the hydrogen-, and/or oxygen- and/or nitrogen-containing fluid(s), if any; and (h) depositing a tellurium-containing film onto the substrate.
