    摘要: Embodiments of an apparatus for generating a chemical precursor used in a vapor deposition processing system are provide which include a canister having a sidewall, a top, and a bottom forming an interior volume which is in fluid communication with an inlet port and an outlet port. The canister contains a plurality of baffles that extend from the bottom to an upper portion of the interior volume and form an extended mean flow path between the inlet port and the outlet port. In one embodiment, the baffles are contained on a prefabricated insert positioned on the bottom of the canister. In one example, an inlet tube may extend from the inlet port into the interior region and be positioned substantially parallel to the baffles. An outlet end of the inlet tube may be adapted to direct a gas flow away from the outlet port, such as towards the sidewall or top of the canister.

    摘要: One embodiment of the gas delivery assembly comprises a covering member having an expanding channel at a central portion of the covering member and having a bottom surface extending from the expanding channel to a peripheral portion of the covering member. One or more gas conduits are coupled to the expanding channel in which the one or more gas conduits are positioned at an angle from a center of the expanding channel. One embodiment of a chamber comprises a substrate support having a substrate receiving surface. The chamber further includes a chamber lid having a passageway at a central portion of the chamber lid and a tapered bottom surface extending from the passageway to a peripheral portion of the chamber lid. The bottom surface of the chamber lid is shaped and sized to substantially cover the substrate receiving surface. One or more valves are coupled to the passageway, and one or more gas sources are coupled to each valve. In one aspect, the bottom surface of the chamber lid may be tapered. In another aspect, a reaction zone defined between the chamber lid and the substrate receiving surface may comprise a small volume. In still another aspect, the passageway may comprise a tapered expanding channel extending from the central portion of the chamber lid. Another embodiment of the chamber comprises a substrate support having a substrate receiving surface. The chamber further comprises a chamber lid having an expanding channel extending from a central portion of the chamber lid and having a tapered bottom surface extending from the expanding channel to a peripheral portion of the chamber lid. One or more gas conduits are disposed around an upper portion of the expanding channel in which the one or more gas conduits are disposed at an angle from a center of the expanding channel. A choke is disposed on the chamber lid adjacent a perimeter of the tapered bottom surface.

    摘要: A method and apparatus for monitoring the delivery of a solid precursor from a vessel to a process chamber via a process gas produced by flowing a carrier gas into the vessel is provided. The precursor typically changes state from a solid to a gas (vapor) through a sublimation process within the chamber. The apparatus comprises a gas analyzer to generate a first signal indicative of a density of the precursor in the process gas and a controller. The controller receives the first signal and a second signal indicative of a volume flow rate of the process gas or the carrier gas and calculates a mass flow rate and/or a total amount consumed of the precursor based on the first and second signals. The controller may calculate an amount precursor remaining in the vessel based on the total amount consumed and an initial amount. The amount of precursor remaining in the vessel may be used by an operator to efficiently schedule replacement or replenishment of the precursor in an effort to minimize material waste and processing down time.
