Abstract:
1. A method of forming a tantalum nitride film, comprising: (a) chemisorbing tantalum from a tantalum containing precursor to form a layer of tantalum containing compound on a substrate, wherein the substrate is maintained at a temperature between 400 degrees Celsius to 600 degrees Celsius; (b) stopping the flow of the tantalum-containing precursor; (c) pulsing a purge gas to the substrate and stopping the flow of the purge Gas to provide a pulse time of less than about 1 second; (d) chemisorbing nitrogen from a nitrogen containing precursor to a layer of nitrogen containing compound on the layer of tantalum containing compound; (e) stopping the flow of the nitrogen containing precursor; (f) pulsing the purge gas to the substrate and stopping the flow of the purge gas to provide a pulse time of less than about 1 second; and repeating (a)-(f) until a desired thickness of the layers of tantalum containing compound and nitrogen containing compound is reached.
