摘要:
A method of treating a metal surface of a portion of a substrate processing system to lower a defect concentration near a processed surface of a substrate includes forming a protective coating on the metal surface, wherein the protective coating includes nickel (Ni) and a fluoropolymer. Forming the protective coating on the metal surface can further include forming a nickel layer on the metal surface, impregnating the nickel layer with a fluoropolymer, and removing fluoropolymer from the surface leaving a predominantly nickel surface so the fluoropolymer is predominantly subsurface. A substrate processing system includes a process chamber into which a reactant gas is introduced, a pumping system for removing material from the process chamber, a first component with a protective coating, wherein the protective coating forms a surface of the component which is exposed to an interior of the substrate processing chamber or an interior of the pumping system. The protective coating includes nickel (Ni) and a flouropolymer.
摘要:
A system for supplying processing fluid to a substrate processing apparatus having walls, the inner surfaces of which define a processing chamber in which a substrate supporting susceptor is located. The system consists of a number of fluid storages, each which stores a separate processing fluid, at least two fluid conduits along which processing fluid flows from the fluid storages to the processing apparatus and a fluid inlet which connects the fluid conduits to the processing chamber. The inlet has a separate fluid passage, corresponding to each of the fluid conduits, formed along it. Each fluid passage opens at or near an inner surface of a wall to define a fluid mixing zone, so that fluid moving along one fluid passage is prevented from mixing with fluid moving along any other passage until reaching the mixing zone.

An apparatus that includes a reflector having a mirrored surface facing down, a glass structure located beneath the reflector, a susceptor within the glass structure having a surface facing up that is capable of holding a part to be processed, and one or more radiant heat sources directed at and located beneath the glass structure.
摘要:
An apparatus for and method of supporting a substrate such as a semiconductor wafer. Silicon carbide sleeves cover substrate support members such as upwardly extending arms of a substrate carrier which is part of a substrate support assembly. The substrate carrier including the upwardly extending arms holds the substrate spaced apart from a platform such as a susceptor during loading and unloading of a processing chamber. The platform defines apertures through which the arms extend. The arms are vertically movable through the apertures with respect to the platform and engage the substrate at the substrate's edge or alternatively, inwardly from the edge.

摘要:
An apparatus and a concomitant method for controlling coolant (air) flow proximate a reaction chamber within a workpiece processing system such that the temperature of a wall of the reaction chamber is maintained at a predefined target temperature. The target temperature is typically a temperature that optimizes a process concurrently being accomplished within the chamber, e.g., utilizing one temperature during deposition processes and a different temperature during cleaning processes. The apparatus contains a temperature measuring device to measure the temperature of the chamber wall. The measured temperature is compared to the predefined target temperature. A closed loop system controls the air flow proximate the chamber walls such that the measured temperature becomes substantially equal to the target temperature. Air flow control is provided by an air flow control device located within an inlet conduit that supplies air to a shroud for channeling the air past the reaction chamber. The shroud forms a portion of a housing which supports and encloses the reaction chamber.

A reflector array employs a number of linear, tubular heater lamps arranged in a circle concentric with the substrate to be heated. Some of the lamps have focusing reflectors and the remainder have dispersive reflectors. A peripheral cylindrical reflector surrounds the lamps and their associated reflectors. The combined reflectors permit balancing the thermal radiation intensity across the surface of the substrate.

摘要:
A lamp array for a thermal processing chamber. The lamp array includes a plurality of lamps arranged in a generally circular array. The plurality of lamps can be arranged in one or more concentric rings to form a generally circular array. Additional lamp arrays can be provided adjacent the circumference of the circular array or outermost concentric ring to provide a generally rectangular heating pattern. At least one row of lamps can be provided tangentially to the circular portion of the lamp array to provide preheating or postheating of process gases in the flow direction of a rectangular processing chamber.
摘要:
A method and apparatus for controlling the radial temperature gradients of a wafer and a susceptor while ramping the temperature of the wafer and susceptor using a first heat source that is primarily directed at a central portion of the wafer, a second heat source that is primarily directed at an outer portion of the wafer, a third heat source that is primarily directed at a central portion of the susceptor, and a fourth heat source that is primarily directed at an outer portion of the susceptor. Ramping of the wafer and susceptor temperature is accomplished by applying power to the first, second, third and fourth heat sources. During ramping, the ratio of the first and second heat source powers is varied as a function of the wafer temperature and the ratio of the third and fourth heat source powers is varied as a function of the susceptor temperature.
