    摘要: A method of forming an organosilicate layer is disclosed. The organosilicate layer is formed by reacting a gas mixture comprising a phenyl-based alkoxysilane compound. The gas mixture may be reacted by applying an electric field thereto. The gas mixture may optionally include an organosilane compound as well as an oxidizing gas. The organosilicate layer is compatible with integrated circuit fabrication processes. In one integrated circuit fabrication process, the organosilicate layer is used as an anti-reflective coating (ARC). In another integrated circuit fabrication process, the organosilicate layer is used as a hardmask. In yet another integrated circuit fabrication process, the organosilicate layer is incorporated into a damascene structure.

    摘要: A method for providing a dielectric film having enhanced adhesion and stability. Pre-deposition, post deposition and post cure treatments enhance adhesion of the dielectric film to an underlying substrate and overlying cap layer. The enhanced film is particularly useful as an intermetal or premetal dielectric layer in an integrated circuit. A pre-deposition treatment process with atomic hydrogen enhances film adhesion by reducing weakly bound oxides on the surface of the substrate. A post-deposition densification process in a reducing atmosphere enhances stability if the film is to be cured ex-situ. In a preferred embodiment, the layer a low dielectric constant film deposited from a process gas of ozone and an organosilane precursor having at least one silicon-carbon (Si—C) bond.

    摘要: The present invention provides systems, methods and apparatus for high temperature (at least about 500-800.degree. C.) processing of semiconductor wafers. The systems, methods and apparatus of the present invention allow multiple process steps to be performed in situ in the same chamber to reduce total processing time and to ensure high quality processing for high aspect ratio devices. Performing multiple process steps in the same chamber also increases the control of the process parameters and reduces device damage. In particular, the present invention can provide high temperature deposition, heating and efficient cleaning for forming dielectric films having thickness uniformity, good gap fill capability, high density, low moisture, and other desired characteristics.
