  • Solid precursor delivery assemblies and related methods
    Patent number: 9297071
    Abstract: A solid precursor delivery assembly generally includes a container having upper and lower portions and chambers defined within the container, including an inlet chamber, an outlet chamber, and first and second precursor chambers. The first and second precursor chambers are configured for holding precursor material within the container. Sintered frits are fixedly coupled and sealed to an interior portion of the container, and define at least part of the chambers within the container. At least one of the sintered frits is configured for retaining precursor material thereon within the first precursor chamber, and at least one of the sintered frits is configured for retaining precursor material thereon within the second precursor chamber. An inlet is coupled to the container for delivering carrier gas into the container, and an outlet is coupled to the container for use in removing vaporized precursor material and carrier gas from the container.
