Patent ID: 6967159

Claim:
A method of manufacturing a semiconductor structure, the method comprising: providing a semiconductor substrate or substrate assembly; providing a vapor comprising one or more refractory metal precursor compounds of the formula MY n (Formula I), wherein M is a refractory metal, each Y is independently a halogen atom or an organic group, and n is an integer selected to match the valence of the metal M; providing a vapor comprising one or more silicon precursor compounds; providing a vapor comprising one or more organic amines; and directing the vapors comprising the one or more refractory metal precursor compounds, the one or more silicon precursor compounds, and the one or more organic amines to the semiconductor substrate or substrate assembly to form a refractory metal silicon nitride layer on a surface of the semiconductor substrate or substrate assembly using an atomic layer deposition process comprising a plurality of deposition cycles using sequential pulsing of the reactants to separate the reaction components.
