  • Patent number: 7560377
    Abstract: A method and apparatus for depositing a low dielectric constant film by reaction of an organosilicon compound and an oxidizing gas comprising carbon at a constant RF power level. Dissociation of the oxidizing gas can be increased prior to mixing with the organosilicon compound, preferably within a separate microwave chamber, to assist in controlling the carbon content of the deposited film. The oxidized organosilane or organosiloxane film has good barrier properties for use as a liner or cap layer adjacent other dielectric layers. The oxidized organosilane or organosiloxane film may also be used as an etch stop and an intermetal dielectric layer for fabricating dual damascene structures. The oxidized organosilane or organosiloxane films also provide excellent adhesion between different dielectric layers.

  • Patent number: 7554103
    Abstract: A pump liner is used to direct a laminar flow of purge gas across a workpiece to remove contaminants or species outgassed or otherwise produced by the workpiece during processing. The pump liner can take the form of a ring having a plurality of injection ports, such as slits of a variety of shapes and/or sizes, opposite a plurality of receiving ports in order to provide the laminar flow. The flow of purge gas is sufficient to carry a contaminant or outgassed species from the processing chamber in order to prevent the collection of the contaminants on components of the chamber. The pump liner can be heated, via conduction and irradiation from a radiation source, for example, in order to prevent the condensation of species on the liner. The pump liner also can be anodized or otherwise processed in order to increase the emissivity of the liner.

  • Patent number: 7554094
    Abstract: An electron-optical arrangement provides a primary beam path for a beam of primary electrons and a secondary beam path for secondary electrons. The electron-optical arrangement includes a magnet arrangement having first, second and third magnetic field regions. The first magnetic field region is traversed by the primary beam path and the secondary beam path. The second magnetic field region is arranged in the primary beam path upstream of the first magnetic field region and is not traversed by the secondary beam path. The first and second magnetic field regions deflect the primary beam path in substantially opposite directions. The third magnetic field region is arranged in the secondary beam path downstream of the first magnetic field region and is not traversed by the first beam path. The first and third magnetic field regions deflect the secondary beam path in a substantially same direction.

  • Publication number: 20090159428
    Abstract: When a magnetron is scanned about the back of a target in a selected complex path having radial components, the erosion profile has a form depending upon the selection of paths. A radial erosion rate profile for a given magnetron is measured. Periodically during scanning, an erosion profile is calculated from the measured erosion rate profile, the time the magnetron spends at different radii, and the target power. The calculated erosion profile may be used to indicate when erosion has become excessive at any location prompting target replacement or to adjust the height of the magnetron above the target for repeated scans. In another aspect of the invention, the magnetron height is dynamically adjusted during a scan to compensate for erosion. The compensation may be based on the calculated erosion profile or on feedback control of the present value of the target voltage for a constant-power target supply.

  • Patent number: 7547643
    Abstract: Adhesion of a porous low K film to an underlying barrier layer is improved by forming an intermediate layer lower in carbon content, and richer in silicon oxide, than the overlying porous low K film. This adhesion layer can be formed utilizing one of a number of techniques, alone or in combination. In one approach, the adhesion layer can be formed by introduction of a rich oxidizing gas such as O2/CO2/etc. to oxidize Si precursors immediately prior to deposition of the low K material. In another approach, thermally labile chemicals such as alpha-terpinene, cymene, and any other non-oxygen containing organics are removed prior to low K film deposition. In yet another approach, the hardware or processing parameters, such as the manner of introduction of the non-silicon containing component, may be modified to enable formation of an oxide interface prior to low K film deposition.
