    摘要: A plasma etch method for etching a dielectric layer and an etch stop layer to reach a metal silicide layer formed thereunder employs for etching the etch stop layer an etchant gas composition comprising a fluorine containing gas and a nitrogen containing gas, preferably with a carrier gas such as argon or helium, but without an oxygen containing gas or a carbon and oxygen containing gas. The plasma etch method is selective for the etch stop layer with respect to the metal silicide layer, thus maintaining the physical and electrical integrity of the metal silicide layer.

    摘要: An integrated advanced method for forming a semiconductor device utilizes a sacrificial stress layer as part of a film stack that enables spatially selective silicide formation in the device. The low-resistance portion of the device to be silicided includes NMOS transistors and PMOS transistors. The stressed film may be a tensile or compressive nitride film. An annealing process is carried out prior to the silicide formation process. During the annealing process, the stressed nitride film preferentially remains over either the NMOS transistors or PMOS transistors, but not both, to optimize device performance. A tensile nitride film remains over the NMOS transistors but not the PMOS transistors while a compressive nitride film remains over the PMOS transistors but not the NMOS transistors, during anneal.

    摘要: A method of manufacturing a semiconductor device is provided. A nickel silicide layer (e.g., NiSi) is formed on a substrate. Next, a hydrogen plasma treatment may be performed on the silicide layer, which may induce the formation of metal/silicon hydride bonds in the silicide layer. An etch stop layer is formed over the silicide layer. A dielectric layer is formed over the etch stop layer. An opening is formed in the dielectric layer. A portion of the etch stop layer is etched away at the opening to expose at least a portion of the silicide layer therebeneath. The etch chemistry mixture used during the etching step preferably includes hydrogen gas. The change in sheet resistance for the exposed silicide layer portion at the opening after the etching step, as compared to before the etching step, is preferably not greater than about 0.10 ohms/square.
