Abstract: Methods of forming indium germanium zinc oxide (IGeZO) films by vapor deposition are provided. The IGeZO films may, for example, serve as a channel layer in a transistor device. In some embodiments atomic layer deposition processes for depositing IGeZO films comprise an IGeZO deposition cycle comprising alternately and sequentially contacting a substrate in a reaction space with a vapor phase indium precursor, a vapor phase germanium precursor, a vapor phase zinc precursor and an oxygen reactant. In some embodiments the ALD deposition cycle additionally comprises contacting the substrate with an additional reactant comprising one or more of NH3, N2O, NO2 and H2O2.

Abstract: Vapor deposition methods and related systems are provided for depositing layers comprising vanadium and oxygen. In some embodiments, the methods comprise contacting a substrate in a reaction space with alternating pulses of a vapor-phase vanadium precursor and a vapor-phase oxygen reactant. The reaction space may be purged, for example, with an inert gas, between reactant pulses. The methods may be used to fill a gap on a substrate surface. Reaction conditions, including deposition temperature and reactant pulse and purge times may be selected to achieve advantageous gap fill properties. In some embodiments, the substrate on which deposition takes place is maintained at a relatively low temperature, for example between about 50° C. and about 185° C.
