    摘要: A method for depositing a low k dielectric film comprising silicon, carbon, and nitrogen is provided. The low k dielectric film is formed by a gas mixture comprising a silicon source, a carbon source, and NR1R2R3, wherein R1, R2, and R3 are selected from the group consisting of alkyl and phenyl groups. The low k dielectric film may be used as a barrier layer, an etch stop, an anti-reflective coating, or a hard mask.

    摘要: A method for providing a dielectric film having a low dielectric constant. The deposited film is particularly useful as an intermetal or premetal dielectric layer in an integrated circuit. The low dielectric constant film is a carbon-doped silicon oxide layer deposited from a thermal, as opposed to plasma, CVD process. The layer is deposited from a process gas of ozone and an organosilane precursor having at least one silicon-carbon (Si—C) bond. During the deposition process the wafer is heated to a temperature less than 250° C. and preferably to a temperature between 100-200° C. Enhancements to the process include adding Boron and/or Phosphorus dopants, two step deposition, and capping the post cured layer.

    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.
