Abstract: A method includes performing a reactant step of a deposition cycle of a deposition process to form a molybdenum (Mo)-based material, performing a Mo precursor step of the deposition cycle, and performing a treatment step of the deposition cycle. Performing the reactant step includes introducing a reactant, performing the Mo precursor step includes introducing a Mo precursor, and performing the treatment step includes introducing a treatment gas. The deposition process is performed at a temperature that is less than or equal to about 450° C.
