    摘要: Embodiments of the present invention generally relates to apparatus for use in film depositions. The apparatus generally include pre-heat rings adapted to be positioned in a processing chamber. In one embodiment, a pre-heat ring includes a ring having an inner edge and an outer edge. The outer edge has a constant radius. The inner edge is oblong-shaped and may have a first portion having a constant radius measured from a center of a circle defined by an outer circumference of the ring. A second portion may have a constant radius measured from a location other than the center of the outer circumference. In another embodiment, a processing chamber includes a pre-heat ring positioned around the periphery of a substrate support. The pre-heat ring includes an inner edge having a first portion, a second portion, and one or more linear portions positioned between the first portion and the second portion.

    摘要: Methods and apparatus for deposition processes are provided herein. In some embodiments, an apparatus may include a substrate support comprising a susceptor plate having a pocket disposed in an upper surface of the susceptor plate and having a lip formed in the upper surface and circumscribing the pocket, the lip configured to support a substrate on the lip; and a plurality of vents extending from the pocket to the upper surface of the susceptor plate to exhaust gases trapped between the backside of the substrate and the pocket when a substrate is disposed on the lip. Methods of utilizing the inventive apparatus for depositing a layer on a substrate are also disclosed.

    摘要: Methods and apparatus for processing a substrate are provided herein. In some embodiments, an apparatus for processing a substrate includes a process chamber having a substrate support disposed therein to support a processing surface of a substrate at a desired position within the process chamber; a first inlet port to provide a first process gas over the processing surface of the substrate in a first direction; a second inlet port to provide a second process gas over the processing surface of the substrate in a second direction different from the first direction, wherein an azimuthal angle measured between the first direction and the second direction with respect to a central axis of the substrate support is up to about 145 degrees; and an exhaust port disposed opposite the first inlet port to exhaust the first and second process gases from the process chamber.
