    摘要: A method is used by a semiconductor processing tool. The method comprises forming a first layer above a substrate layer, and forming an inorganic bottom antireflective coating layer above the first layer by introducing at least two gases at a preselected ratio into the semiconductor processing tools. A signal indicating that the semiconductor processing tool has been serviced is received, and the ratio of the gases is varied in response to receiving the signal to control optical parameters of the bottom antireflective coating layer to enhance subsequent photolithographic processes.

    摘要: A method for semiconductor device fabrication is provided. The present invention is directed towards using at least one patterned dummy wafer along with one or more product wafers in a film deposition system to create a sidewall layer thickness variation that is substantially uniform across all product wafers. The at least one patterned dummy wafer may have a high density patterned substrate surface with a topography that is different from or substantially similar to a topography of the one or more product wafers. Furthermore, in a batch type Chemical Vapor Deposition (CVD) system, the at least one patterned dummy wafer may be placed near a gas inlet of the CVD system. At least one patterned dummy wafer may be placed near an exhaust of the CVD system. Additionally, the patterned dummy wafers may be reusable in subsequent film deposition processes.

    摘要: Methods and systems of fabricating a wordline protection structure are described. As described, the wordline protection structure includes a polysilicon structure formed adjacent to a memory core region. The polysilicon structure includes first doped region positioned on a core side of the polysilicon structure and a second doped region positioned on a spine side of the polysilicon structure. An un-doped region positioned between the first and second doped regions. A conductive layer is formed on top of the polysilicon structure and arranged so that it does not contact the un-doped region at either the transition between the first doped region and the un-doped region or the second doped region and un-doped region.

    摘要: A method for semiconductor device fabrication is provided.

The at least one patterned dummy wafer may have a high density patterned substrate surface with a topography that is different from or substantially similar to a topography of the one or more product wafers. Furthermore, in a batch type Chemical Vapor Deposition (CVD) system, the at least one patterned dummy wafer may be placed near a gas inlet of the CVD system. In another embodiment, at least one patterned dummy wafer may be placed near an exhaust of the CVD system. Additionally, the patterned dummy wafers may be reusable in subsequent film deposition processes.
