    摘要: Methods for conformal radical oxidation of structures are provided. The method comprises positioning a substrate in a processing region of a processing chamber. The method further comprises flowing hydrogen gas into a precursor activator at a first flow rate, wherein the precursor activator is fluidly coupled with the processing region. The method further comprises flowing oxygen gas into the precursor activator at a second flow rate. The method further comprises flowing argon gas into the precursor activator at a third flow rate. The method further comprises generating a plasma in the precursor activator from the hydrogen gas, oxygen gas, and argon gas. The method further comprises flowing the plasma into the processing region. The method further comprises exposing the substrate to the plasma to form an oxide film on the substrate, wherein a growth rate of the oxide film is controlled by adjusting the third flow rate.

    摘要: Embodiments of the present disclosure generally relate to a processing chamber for conformal oxidation of high aspect ratio structures. The processing chamber includes a chamber body with a first side and a second side opposite the first side, and a flow assembly disposed in the first side. The flow assembly includes a flow divider to direct fluid flow away from a center of a substrate disposed in a processing region of the processing chamber. The flow divider includes a crescent shaped first side, a top, and a bottom. The processing chamber also includes a distributed pumping structure located adjacent to the second side. The flow assembly is designed to reduce flow constriction of the radicals, leading to increased radical concentration and flux.

    摘要: A gas supply member includes a first side opposite a second side and an inner surface defining a first opening extending between the first and second sides. The gas supply member includes a third side orthogonal to the first side, the third side includes a first extension that has a face partially defining the second side, and the first extension includes a first plurality of holes extending through the first extension to the face. The gas supply member includes a fourth side opposite the third side, the fourth side includes a protrusion that has a face partially defining the second side. The gas supply member also includes a baffle disposed adjacent to the inner surface, the baffle includes a first portion extending from the inner surface and a second portion attached to the first portion, and the second portion orthogonal to the first portion and parallel to the third side.

    摘要: Embodiments of the present disclosure provide apparatuses for improving gas distribution during thermal processing. In one or more embodiments, an apparatus includes a body, an angled gas source assembly, and a gas injection channel. The gas injection channel has a first half-angle and a second half-angle. The first half-angle is different from the second half-angle. The use of an improved side gas assembly in a processing chamber to direct gas from the center toward the edge of the substrate advantageously controls growth uniformity throughout the substrate. Surprisingly, directing gas through a gas channel with non-uniform half-angles will significantly increase the reaction at or near the edge of the substrate, thereby leading to an improved overall thickness uniformity of the substrate.
