    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.

    摘要: A method of reducing stress on a substrate in a thermal processing chamber. The method includes the steps of supporting a first portion of a substrate by means of contacting the same such that a second portion of the substrate is not contacted, part of the second portion forming one wall of a cavity, and flowing a gas into the cavity such that the pressure of the gas exerts a force on the second portion to at least partially support the second portion.

    摘要: A method of processing a disk-shaped substrate, or wafer, during a chemical vapor process includes a backside purge of the substrate with a purge gas. The backside purge is obtained by spinning the substrate about a central axis, directing a flow of the purge gas over the backside of the spinning substrate, and causing the purge gas to flow in an outward radial direction with the spinning substrate. An apparatus in a vapor processing system structured for conducting the backside purge includes a support mechanism structured and arranged to support the substrate and spin the substrate about a central axis, and a conduit coupled to a source of purge gas, structured and arranged to direct a flow of the purge gas over a backside of the substrate while the substrate is spinning such that the spinning substrate causes the purge gas to flow radially outward.
