    摘要: A precursor monitoring assembly for use in reactor systems to provide real-time and direct measurements of the availability of source materials from a source vessel. The assembly includes one or more force or load sensors, such as load cells, positioned between a bottom wall of an interior tray and an exterior wall (e.g., a base of a source vessel) and/or outside the source vessel. A signal conditioning element processes the output electrical signals from the sensors, then a controller processes the output signals from the signal conditioning components with a conversion factor, for example, to determine a current weight of source material stored in the source vessel. The controller uses this weight to calculate the amount of available source material or chemistry in the source vessel.

    摘要: Herein disclosed are systems and methods related to solid source chemical vaporizer vessels and multiple chamber deposition modules. In some embodiments, a solid source chemical vaporizer includes a housing base and a housing lid. Some embodiments also include a first and second tray configured to be housed within the housing base, wherein each tray defines a first serpentine path adapted to hold solid source chemical and allow gas flow thereover. In some embodiments, a multiple chamber deposition module includes first and second vapor phase reaction chambers and a solid source chemical vaporizer vessel to supply each of the first and second vapor phase reaction chambers.

    摘要: An apparatus and method for depositing a transition metal nitride film on a substrate by atomic layer deposition in a reaction space defined by an at least one chamber wall and showerhead is disclosed. The apparatus may include, a substrate support disposed within the reaction space, the substrate support configured for supporting at least one substrate and a temperature control system for controlling a temperature of the at least one chamber wall at those portions of the at least one chamber wall that is exposed to a vapor phase reactant. The apparatus may also include a temperature control system for controlling a temperature of the showerhead, wherein the temperature control system for controlling a temperature of the showerhead is configured to control the temperature of the showerhead to a temperature of between approximately 80° C. and approximately 160° C. The method may include, providing at least one substrate on a substrate support within the reaction space and controlling a temperature of the at least one chamber wall at least at those portions of the at least one chamber wall that is exposed to a vapor phase reactant and controlling a temperature of a showerhead. The method may also include, alternatively and sequentially feeding at least two vapor phase reactants into the reaction space, wherein the temperature of the showerhead is controlled to a temperature between approximately 80° C. and approximately 160° C.

    摘要: 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.
