  • Publication number: 20060270221
    Abstract: A method of processing a substrate including depositing a low dielectric constant film comprising silicon, carbon, and oxygen on the substrate and depositing an oxide rich cap on the low dielectric constant film is provided. The low dielectric constant film is deposited from a gas mixture comprising an organosilicon compound and an oxidizing gas in the presence of RF power in a chamber. The RF power and a flow of the organosilicon compound and the oxidizing gas are continued in the chamber after the deposition of the low dielectric constant film at flow rates sufficient to deposit an oxide rich cap on the low dielectric constant film.

  • Publication number: 20060252273
    Abstract: A method of processing a substrate including depositing a transition layer and a dielectric layer on a substrate in a processing chamber are provided. The transition layer is deposited from a processing gas including an organosilicon compound and an oxidizing gas. The flow rate of the organosilicon compound is ramped up during the deposition of the transition layer such that the transition layer has a carbon concentration gradient and an oxygen concentration gradient. The transition layer improves the adhesion of the dielectric layer to an underlying barrier layer on the substrate.

  • Publication number: 20060249175
    Abstract: An ultraviolet (UV) cure chamber enables curing a dielectric material disposed on a substrate and in situ cleaning thereof. A tandem process chamber provides two separate and adjacent process regions defined by a body covered with a lid having windows aligned respectively above each process region. One or more UV bulbs per process region that are covered by housings coupled to the lid emit UV light directed through the windows onto substrates located within the process regions. The UV bulbs can be an array of light emitting diodes or bulbs utilizing a source such as microwave or radio frequency. The UV light can be pulsed during a cure process. Using oxygen radical/ozone generated remotely and/or in-situ accomplishes cleaning of the chamber. Use of lamp arrays, relative motion of the substrate and lamp head, and real-time modification of lamp reflector shape and/or position can enhance uniformity of substrate illumination.
