    摘要: A method of manufacturing a semiconductor device includes forming a first level, forming a first barrier layer over the first level, forming a dielectric layer over the first barrier layer, forming an opening having side surfaces through the dielectric layer, etching the first barrier layer, and filling the opening with metal to form a first metal feature. The process also includes the step of replacing hydroxyl terminated ions on the side surfaces. This step of replacing the hydroxyl terminated ions can occur after the opening is formed or after the first barrier layer is etched. A semiconductor device produced by the method of manufacturing is also disclosed.

    摘要: A gate region of a transistor is prepared for receiving a deposit of metal. A chemical mechanical polishing process is performed to reduce thickness of an insulation layer above the gate region. At the end of the chemical mechanical polishing process, a portion of the insulating layer remains above the gate region. An etch process is performed to remove the portion of the insulating layer remaining above the gate region. The etch process also removes a portion of polysilicon within the gate region and removes a top portion of spacers on either side of the gate region. A polysilicon selective etch-back is performed to remove an additional portion of the polysilicon within the gate region.

    摘要: An isolation structure on an integrated circuit is formed using a shallow trench isolation process. A layer of buffer oxide is formed on a substrate. A layer of nitride is formed on the layer of buffer oxide. The layer of nitride and the layer of buffer oxide are patterned to form a trench area. The substrate including the trench area is subjected to a plasma comprising H.sub.2 O vapor, and a gaseous fluorocarbon or a fluorinated hydrocarbon gas to clean impurities on the trench area. The substrate is etched to form a trench within the trench area.
