    摘要: Embodiments in accordance with the present invention relate to a number of techniques, which may be applied alone or in combination, to reduce charge damage of substrates exposed to electron beam radiation. In one embodiment, charge damage is reduced by establishing a robust electrical connection between the exposed substrate and ground. In another embodiment, charge damage is reduced by modifying the sequence of steps for activating and deactivating the electron beam source to reduce the accumulation of charge on the substrate. In still another embodiment, a plasma is struck in the chamber containing the e-beam treated substrate, thereby removing accumulated charge from the substrate. In a further embodiment of the present invention, the voltage of the anode of the e-beam source is reduced in magnitude to account for differences in electron conversion efficiency exhibited by different cathode materials.

    摘要: A method of forming an integrated circuit using a fluoro-organosilicate layer is disclosed. The fluoro-organosilicate layer is formed by applying an electric field to a gas mixture comprising a fluoro-organosilane compound and an oxidizing gas. The fluoro-organosilicate layer is compatible with integrated circuit fabrication processes. In one integrated circuit fabrication process, the fluoro-organosilicate layer is used as a hardmask. In another integrated circuit fabrication process, the fluoro-organosilicate layer is incorporated into a damascene structure.

    摘要: A method and apparatus for controlling the introduction of contaminates into a deposition chamber that occur naturally within the chamber components. The CVD chamber is "seasoned" with a protective layer after a dry clean operation and before a substrate is introduced into the chamber. The deposited seasoning layer has a lower diffusion rate for typical contaminants in relation to the chamber component materials and covers the chamber component, reducing the likelihood that the naturally occurring contaminants will interfere with subsequent processing steps. After deposition of the seasoning layer is complete, the chamber is used for one to n substrate deposition steps before being cleaned by another clean operation as described above and then reseasoned.

    摘要: Compressive stress in a film of a semiconductor device may be controlled utilizing one or more techniques, employed alone or in combination. A first set of embodiments increase silicon nitride compressive stress by adding hydrogen to the deposition chemistry, and reduce defects in a device fabricated with a high compressive stress silicon nitride film formed in the presence of hydrogen gas. A silicon nitride film may comprise an initiation layer formed in the absence of a hydrogen gas flow, underlying a high stress nitride layer formed in the presence of a hydrogen gas flow. A silicon nitride film formed in accordance with an embodiment of the present invention may exhibit a compressive stress of 2.8 GPa or higher.
