摘要： A substrate processing system for processing multiple substrates is provided and generally includes at least one processing platform and at least one staging platform. Each substrate is positioned on a substrate carrier disposed on a substrate support assembly. Multiple substrate carriers, each is configured to carry a substrate thereon, are positioned on the surface of the substrate support assembly. The processing platform and the staging platform, each includes a separate substrate support assembly, which can be rotated by a separate rotary track mechanism. Each rotary track mechanism is capable of supporting the substrate support assembly and continuously rotating multiple substrates carried by the substrate carriers and disposed on the substrate support assembly. Each substrate is thus processed through at least one shower head station and at least one buffer station, which are positioned at a distance above the rotary track mechanism of the processing platform. Each substrate can be transferred between the processing platform and the staging platform and in and out the substrate processing system.

摘要： A method of filling a trench is described and includes depositing a dielectric liner with a high ratio of silicon oxide to dielectric liner etch rate in fluorine-containing etch chemistries. Silicon oxide is deposited within the trench and etched to reopen or widen a gap near the top of the trench. The dielectric liner protects the underlying substrate during the etch process so the gap can be made wider. Silicon oxide is deposited within the trench again to substantially fill the trench.

摘要： A method for providing a dielectric film having enhanced adhesion and stability. The method includes a post deposition treatment that densifies the film in a reducing atmosphere to enhance stability if the film is to be cured ex-situ. The densification generally takes place in a reducing environment while heating the substrate. The densification treatment is particularly suitable for silicon-oxygen-carbon low dielectric constant films that have been deposited at low temperature.

摘要： Embodiments in accordance with the present invention relate to multi-stage curing processes for chemical vapor deposited low K materials. In certain embodiments, a combination of electron beam irradiation and thermal exposure steps may be employed to control selective outgassing of porogens incorporated into the film, resulting in the formation of nanopores. In accordance with one specific embodiment, a low K layer resulting from reaction between a silicon-containing component and a non-silicon containing component featuring labile groups, may be cured by the initial application of thermal energy, followed by the application of radiation in the form of an electron beam.
