    摘要: A method of forming a semiconductor device provides a gate electrode on a substrate and forms a polysilicon reoxidation layer over the substrate and the gate electrode. A nitride layer is deposited over the polysilicon reoxidation layer and anisotropically etched The etching stops on the polysilicon reoxidation layer, with nitride offset spacers being formed on the gate electrode. The use of the polysilicon reoxidation layer as an etch stop layer prevents the gouging of the silicon substrate underneath the nitride layer, while allowing the offset spacers to be formed.

    摘要: At least one patterned dielectric layer is provided within a transistor arrangement to prevent a local interconnect from electrically contacting,the gate conductor due to misalignments during the damascene formation of etched openings used in forming local interconnects. By selectively etching through a plurality of dielectric layers during the local interconnect etching process, the patterned dielectric layer is left in place to prevent short-circuiting of the gate to an adjacent local interconnect that is slightly misaligned.

    摘要: According to one exemplary embodiment, a method for forming a field effect transistor on a substrate comprises a step of forming disposable spacers adjacent to a gate stack situated on the substrate, where the disposable spacers comprise amorphous carbon. The disposable spacers can be formed by depositing a layer of amorphous carbon on the gate stack and anisotropically etching the layer of amorphous carbon. The method further comprises forming source and drain regions in the substrate, where the source and drain regions are situated adjacent to the disposable spacers. According to this exemplary embodiment, the method further comprises removing the disposable spacers, where the removal of the disposable spacers causes substantially no gouging in the substrate. The disposable spacers can be removed by using a dry etch process. The method can further comprise forming extension regions in the substrate adjacent to the gate stack prior to forming the disposable spacers.

    摘要: A deposition method allows for the forming of a uniform dielectric stop layer that is substantially void of defects caused by outgassing effects. The stop layer is deposited in a reactor chamber at a higher than normal temperature of at least 480.degree. C. The stop layer is then combined with an overlying dielectric layer to provide an inter-level dielectric structure through which a local interconnect can be formed to provide a conductive path to one or more regions of the underlying semiconductor devices.

    摘要: A method for forming an alloy film by cooling a substrate during a sputter deposition process. In one embodiment, aluminum-copper (Al-Cu) alloy film is deposited on a substrate while the substrate is maintained at a temperature lower than 100.degree. C. during a sputter deposition process, thereby reducing the precipitation of CuAl.sub.2. The substrate is cooled by pumping a coolant gas through a cooled platen and against the substrate during processing. Subsequent film formation prior to etching is also performed below 100.degree. C. to prevent precipitation of CuAl.sub.2 until the Al-Cu alloy film is etched. Large crystal grains are formed by annealing the substrate after etching.
