    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.

    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.
