发明名称 Cyclical deposition of tungsten nitride for metal oxide gate electrode
摘要 A method for depositing a tungsten nitride layer is provided. The method includes a cyclical process of alternately adsorbing a tungsten-containing compound and a nitrogen-containing compound on a substrate. The barrier layer has a reduced resistivity, lower concentration of fluorine, and can be deposited at any desired thickness, such as less than 100 angstroms, to minimize the amount of barrier layer material.
