    摘要： A method of fabricating an integrated circuit on a wafer includes forming a gate electrode stack over a gate dielectric and forming nitride spacers along sidewalls of the gate electrode stack other than along lowermost portions of the sidewalls. Subsequently, a reoxidation process is performed with respect to the gate dielectric. By providing the nitride spacers along exposed surfaces of conductive barrier and metal layers of the word line stack, those surfaces can be passivated, thereby preventing or reducing the conversion of those layers to non-conductive compounds during the reoxidation process. At the same time, the nitride spacers can be formed so that they do not interfere with the subsequent reoxidation of the gate dielectric. An integrated circuit having a gate electrode stack with nitride spacers extending along sidewalls of the gate electrode stack other than along lowermost portions of the sidewalls is also disclosed.

    摘要： A process for the in situ formation of a selective contact and a local interconnect on a semiconductor substrate. The exposed semiconductor substrate regions of a semiconductor device structure may be treated in a plasma to enhance the adhesiveness of a selective contact thereto. The semiconductor device structure is positioned within a reaction chamber, wherein a selective contact is deposited onto the exposed semiconductor substrate regions, Any residual selective contact material may be removed from oxide surfaces either intermediately or after selective contact deposition. While the semiconductor device remains in the reaction chamber, a local interconnect is deposited over the semiconductor device structure. The local interconnect may then be patterned. Subsequent layers may be deposited over the local interconnect. The present invention also includes semiconductor device structures formed by the inventive process.

    摘要： A method of reducing the amount of halogenated materials in a halogen-containing environment. The method comprises introducing an aluminum compound into the halogen-containing environment, reacting the aluminum compound with the halogenated material to form a gaseous reaction product, and removing the gaseous reaction product from the environment. The aluminum compound may be a trialkylaluminum compound, an alane, an alkylaluminum hydride, an alkylaluminum halide, an alkylaluminum sesquihalide, or an aluminum sesquihalide. The aluminum compound may alternatively form a solid aluminum product, which is deposited on a surface associated with the halogen-containing environment or onto a semiconductor disposed therewithin. The halogenated material is incorporated into the solid aluminum product, forming an inert film within which the halogenated material is trapped.

    摘要： Some embodiments include methods of forming dielectric materials associated with semiconductor constructions. A semiconductor substrate surface having two different compositions may be exposed to a first silanol, then to organoaluminum to form a monolayer, and finally to a second silanol to form a dielectric material containing aluminum from the organoaluminum together with silicon and oxygen from the second silanol. Alternatively, or additionally, an organoaluminum monolayer may be formed across a semiconductor substrate, and then exposed to silanol within a deposition chamber, with the silanol being provided in two doses. Initially, a first dose of the silanol is injected the chamber, and then the first dose is flushed from the chamber to remove substantially all unreacted silanol from within the chamber. Subsequently, the second dose of silanol is injected into the chamber. Some embodiments include semiconductor constructions.

    摘要： A method of forming trench isolation includes etching first trench lines into semiconductive material of a semiconductor substrate. First isolation material is formed within the first trench lines within the semiconductive material. After forming the first isolation material within the first trench lines, second trench lines are etched into semiconductive material of the substrate between the first trench lines such that the first trench lines and second trench lines alternate. Second isolation material is formed within the second trench lines within the semiconductive material. Alternate and additional aspects are contemplated.
