    摘要: Methods and apparatus for preparing a porous low-k dielectric material on a substrate are provided. The methods optionally involve the use of ultraviolet radiation to react with and remove porogen from a porogen containing precursor film leaving a porous dielectric matrix and further exposing the dielectric matrix to ultraviolet radiation to increase the mechanical strength of the dielectric matrix. Some methods involve activating a gas to create reactive gas species that can clean a reaction chamber. One disclosed apparatus includes an array of multiple ultraviolet sources that can be controlled such that different wavelengths of light can be used to irradiate a sample at a time.

    摘要: Methods of preparing low-k carbon-doped oxide (CDO) films having high mechanical strength are provided. The methods involve contacting the substrate with a CDO precursor to deposit the film typically using a plasma-enhanced chemical vapor deposition (PECVD) method. After the film is deposited, it is exposed to ultraviolet radiation in a manner that increases cross-linking and/or lowers the dielectric constant of the film. The resulting films have ultra-low dielectric constants, e.g., about 2.5, but also high mechanical strength, e.g., a modulus of at least about 7.5 GPa. In certain embodiments, a single hydrocarbon precursor is used, resulting in an improved process for obtaining ULK films that does not require dual (porogen and backbone) precursors.

    摘要: A temperature controlled showerhead for chemical vapor deposition (CVD) chambers enhances heat dissipation to enable accurate temperature control with an electric heater. Heat dissipates by conduction through a showerhead stem and fluid passageway and radiation from a back plate. A temperature control system includes one or more temperature controlled showerheads in a CVD chamber with fluid passageways serially connected to a heat exchanger.
