Claim 18:
19. A method of forming a molybdenum film, the method comprising:
exposing a substrate surface to a plurality of ALD cycles to form a molybdenum oxide film with a thickness in a range of 0.2 nm to about 100 nm, each cycle comprising exposure to an organometallic molybdenum precursor and an oxidant, the organometallic molybdenum precursor comprising one or more of CpMo(CO)2(NO) or MeCpMo(CO)2(NO), the molybdenum oxide film having a carbon content of less than or equal to about 5 atomic percent; and
exposing the molybdenum oxide film to a reductant to form a molybdenum film, the molybdenum film having an impurity content of less than or equal to about 5 atomic percent.
