摘要： A process to form a copper-silicon-nitride layer on a copper surface on a semiconductor wafer is described. The process may include the step of exposing the wafer to a first plasma made from helium. The process may also include exposing the wafer to a second plasma made from a reducing gas, where the second plasma removes copper oxide from the copper surface, and exposing the wafer to silane, where the silane reacts with the copper surface to selectively form copper silicide. The process may further include exposing the wafer to a third plasma made from ammonia and molecular nitrogen to form the copper silicon nitride layer.

摘要： A method for forming a compressive stress carbon-doped silicon nitride layer is provided. The method includes forming an initiation layer and a bulk layer thereon, wherein the bulk layer has a compressive stress of between about −0.1 GPa and about −10 GPa. The initiation layer is deposited from a gas mixture that includes a silicon and carbon-containing precursor and optionally a nitrogen and/or source but does not include hydrogen gas. The bulk layer is deposited from a gas mixture that includes a silicon and carbon-containing precursor, a nitrogen source, and hydrogen gas. The initiation layer is a thin layer that allows good transfer of the compressive stress of the bulk layer therethrough to an underlying layer, such as a channel of a transistor.

摘要： Adhesion between a copper metallization layer and a dielectric barrier film may be promoted by stabilizing a flow of a silicon-containing precursor in a divert line leading to the chamber exhaust. The stabilized gas flow is then introduced to the processing chamber to precisely form a silicide layer over the copper. This silicidation step creates a network of strong Cu—Si bonds that prevent delamination of the barrier layer, while not substantially altering the sheet resistance and other electrical properties of the resulting metallization structure.
