    Abstract: Devices and methods for selectively oxidizing silicon are described herein. An apparatus for selective oxidation of exposed silicon surfaces includes a thermal processing chamber with a plurality of walls, first inlet connection and a second inlet connection, wherein the walls define a processing region within the processing chamber, a substrate support within the processing chamber, a hydrogen source connected with the first inlet connection, a heat source connected with the hydrogen source, and a remote plasma source connected with the second inlet connection and an oxygen source. A method for selective oxidation of non-metal surfaces, can include positioning a substrate in a processing chamber at a temperature less than 800° C., flowing hydrogen into the processing chamber, generating a remote plasma comprising oxygen, mixing the remote plasma with the hydrogen gas in the processing chamber to create an activated processing gas, and exposing the substrate to the activated gas.

    Abstract: Embodiments of substrate support rings providing more uniform thickness of layers deposited or grown on a substrate are provided herein. In some embodiments, a substrate support ring includes: an inner ring with a centrally located support surface to support a substrate; and an outer ring extending radially outward from the support surface, wherein the outer ring comprises a reaction surface area disposed above and generally parallel to a support plane of the support surface, and wherein the reaction surface extends beyond the support surface by about 24 mm to about 45 mm.

    Abstract: Embodiments of the disclosure generally relate to a support ring that supports a substrate in a process chamber. In one embodiment, the support ring comprises an inner ring, an outer ring connecting to an outer perimeter of the inner ring through a flat portion, an edge lip extending radially inwardly from an inner perimeter of the inner ring to form a supporting ledge, and a substrate support extending upwardly from a top surface of the edge lip. The substrate support may be a continuous ring-shaped body disposed around a circumference of the edge lip. The substrate support supports a substrate about its entire periphery from the back side with minimized contact surface to thermally disconnect the substrate from the edge lip. Particularly, the substrate support provides a substantial line contact with the back surface of the substrate.
