    Abstract: Various embodiments of the present technology may provide methods and apparatus for cleaning a source vessel. The source vessel may be filled or partially filled with a solvent to form a solution. The solution is removed from the source vessel and contained in a waste vessel that is connected to the source vessel. The waste vessel may have a bellow or other mechanism inside of it to create a negative pressure in the waste vessel to pull the solution out of the source vessel and into the waste vessel. Alternatively, a liquid pump may be used to pull the solution from the source vessel to the waste vessel.

  • Patent number: 11959168
    Abstract: The present disclosure is generally directed to a solid source precursor delivery system. More specifically, the present disclosure is directed to a solid source precursor vessel that can be utilized to vaporize a supply of solid precursor stored within the vessel. The disclosed source vessel utilizes a plurality of individual cavities or pockets within the interior of the vessel. Each individual pocket may be loaded with precursor. In an arrangement, the pockets may be loaded with pre-formed blocks of compressed precursor material that typically have a higher density than was previously achieved when packing solid precursor within a source vessel. The increased density of the solid precursor material increases a capacity of the source vessel resulting in longer intervals between replacement and/or refilling the source vessel.
