    摘要: A substrate support comprising a shelf having a surface sloped at an angle such that the support contacts the substrate substantially at an edge portion of the substrate. The angle of the shelf is greater than an angle of the edge portion of the substrate. The surface of the shelf may be machined or polished to improve its smoothness. The substrate support thereby reduces the effect and severity of scratches on the substrate caused by the support. As a result, the substrate support improves substrate yield.

    摘要: A substrate support mechanism including a housing made of a magnetically permeable material; a pin located substantially within the housing and having an upper end extending up into a passage which extends up through the bottom of the chamber and into the cavity which contains a substrate during processing; a first magnet assembly on the inside of the housing and mounted on the pin; a carriage structure located outside of the housing; and a second magnet assembly mounted on the carriage structure, wherein the first and second magnet assemblies are positioned relative to each other so that the second magnet assembly causes the pin and the first magnet assembly to magnetically levitate within the housing.

    摘要: Accomodations for a magnetically levitated rotating system in an RTP chamber are provided. The system includes a magnetically permeable rotor; a cylindrical thin wall concentric with and surrounding the rotor; and a magnetic stator assembly adjacent the cylindrical thin wall. The radial distance between the rotor and the magnetic stator assembly is small enough that a magnetic field created by the stator assembly magnetically levitates the rotor but is great enough that the rotor does not physically contact the thin wall upon thermal expansion. The system is such that the relative positions of a plurality of sensors which determine the position of a rotating frame is maintained upon dismantling. Thermal isolation of the area including the rotor is accomplished from the reactive gases in a processing area of the RTP chamber. The rotor may be cooled by a number of cooling chambers formed within the chamber.
