Abstract:
A method of forming a layer on a substrate, the method comprising:providing a substrate; providing a vapor comprising one or more refractory metal precursor compounds of the formula MYn (Formula I), wherein M is a refractory metal, each Y is independently a halogen atom, and n is an integer selected to match the valence of the metal M; providing a vapor comprising one or more disilazanes of the formula (R)xH3-xSiNHSi(R)xH3-x, wherein each R is independently an organic group, and x is 1 to 3; and directing the vapors comprising the one or more refractory metal precursor compounds and the one or more disilazanes to the substrate to form a refractory metal nitride layer on one or more surfaces of the substrate.
