Patent ID: 8425978

Claim:
A method of forming a conductive fluorine-doped metal oxide layer on a substrate by chemical vapor deposition, the method comprising: heating the substrate in a processing chamber; introducing a metal-containing precursor, and a fluorine-containing precursor to the processing chamber; and reacting the precursors to deposit the fluorine-doped metal oxide layer on the substrate; wherein the fluorine-containing precursor is a hydrofluorinated ether having the formula; R 1 —O—R2 wherein R 1 and R 2 are independently a C 1 -C 4 alkyl group which may have one or more hydrogens (—H) substituted with fluorine (—F) groups, and wherein if either R 1 or R 2 is an unsubstituted alkyl group with no fluorine groups, then the other group R 1 or R 2 has at least one hydrogen substituted with a fluorine group; and wherein the hydrofluorinated ether is selected from the group consisting of C 3 F 7 OCH 3 , C 4 F 9 OCH 3 , C 4 F 9 OC 2 H 5 , CF 3 OCH 3 , CHF 2 OCHF 2 , CF 3 CF 2 OCH 3 , CF 3 OCHFCF 3 , and CF 3 COCBr 2 H.
