    摘要: Disclosed herein is a method for applying plasma-resistant coatings for use in semiconductor processing apparatus. The coatings are applied over a substrate which typically comprises an aluminum alloy of the 2000 series or the 5000 through 7000 series. The coating typically comprises an oxide or a fluoride of Y, Sc, La, Ce, Eu, Dy, or the like, or yttrium-aluminum-garnet (YAG). The coating may further comprise about 20 volume % or less of Al2O3. The coatings are typically applied to a surface of an aluminum alloy substrate or an anodized aluminum alloy substrate using a technique selected from the group consisting of thermal/flame spraying, plasma spraying, sputtering, and chemical vapor deposition (CVD). To provide the desired corrosion resistance, it is necessary to place the coating in compression. This is accomplished by controlling deposition conditions during application of the coating.

The gas distribution plate includes a plurality of through-holes, which are typically crescent-shaped. Through-holes which have been formed in the solid yttrium oxide-comprising substrate by ultrasonic drilling perform particularly well. The solid yttrium oxide-comprising substrate-typically comprises at least 99.9% yttrium oxide, and has a density of at least 4.92 g/cm3, a water absorbency of about 0.02% or less, and an average grain size within the range of about 10 μm to about 25 μm. Also disclosed herein are methods for fabricating and cleaning the yttrium oxide-comprising gas distribution plate.

    摘要: An integrated in situ etch process performed in a multichamber substrate processing system having first and second etching chambers. In one embodiment the first chamber includes an interior surface that has been roughened to at least 100 Ra and the second chamber includes an interior surface that has a roughness of less than about 32 Ra. The process includes transferring a substrate having formed thereon in a downward direction a patterned photoresist mask, a dielectric layer, a barrier layer and a feature in the substrate to be contacted into the first chamber where the dielectric layer is etched in a process that encourages polymer formation over the roughened interior surface of the chamber. The substrate is then transferred from the first chamber to the second chamber under vacuum conditions and, in the second chamber, is exposed to a reactive plasma such as oxygen to strip away the photoresist mask deposited over the substrate. After the photoresist mask is stripped, the barrier layer is etched through to the feature to be contacted in the second chamber of the multichamber substrate processing system using a process that discourages polymer formation over the relatively smooth interior surface of the second chamber. All three etching steps are performed in a system level in situ process so that the substrate is not exposed to an ambient between steps. In some embodiments the interior surface of the first chamber has a roughness between 100 and 200 Ra and in other embodiments the roughness of the first chamber's interior surface is between 110 and 160 Ra.

    摘要: A process kit is described that resists plasma erosion, preserves the spatial uniformity of plasma properties, reduces particle generation in the chamber, and significantly enhances the lifetime of the process kit. A layer of polymer material covers the top surface of the process kit. The polymer material is fluorocarbon-based and not reactive with the species in the plasma. The polymer material not only protects the process kit from progressive erosion, but also prevents the generation of particles in the chamber. The polymer material has similar permittivity to that of the process kit and therefore maintains the spatial uniformity of plasma properties, e.g., etch rate, near the wafer perimeter. The thickness of the layer is controlled between 0.5 and 1.5 mm such that the difference between its coefficient of thermal expansion and that of the process kit will not cause the layer to peel off the process kit's top surface.

    摘要: Described herein are exemplary methods and apparatuses for fabricating a gas distribution showerhead assembly in accordance with one embodiment. In one embodiment, a method includes providing a gas distribution plate having a first set of through-holes for delivering processing gases into a semiconductor processing chamber. The first set of through-holes is located on a backside of the plate (e.g., Aluminum substrate). The method includes spraying (e.g., plasma spraying) a coating material (e.g., Ytrria based material) onto a cleaned surface of the gas distribution plate. The method includes removing (e.g., surface grinding) a portion of the coating material from the surface to reduce a thickness of the coating material. The method includes forming (e.g., UV laser drilling, machining) a second set of through-holes in the coating material such that the through-holes are aligned with the first-set of through-holes.
