    摘要： Embodiments of the invention provide chemical precursor ampoules that may be used during vapor deposition processes. In one embodiment, an apparatus for generating a chemical precursor gas used in a vapor deposition processing system is provided which includes a canister having a sidewall, a top, and a bottom forming an interior volume and a solid precursor material at least partially contained within a lower region of the interior volume. The apparatus further contains an inlet port and an outlet port in fluid communication with the interior volume and an inlet tube connected to the inlet port and positioned to direct a carrier gas towards the sidewall and away form the outlet port. In one example, the solid precursor contains pentakis(dimethylamido) tantalum (PDMAT). In another example, the apparatus contains a plurality of baffles that form an extended mean flow path between the inlet port and the outlet port.

    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： 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.
