  • Publication number: 20230130079
    Abstract: A system includes a vaporizer vessel. The vaporizer vessel includes an outlet fluidly connected to the vaporizer vessel. A heater is configured to heat the vaporizer vessel. A valve is configured to regulate a pressure of a vaporized material at the outlet. In response to the pressure at the outlet being outside a set pressure range, the heater is configured to increase or decrease heat to the vaporizer vessel.

  • Publication number: 20230112884
    Abstract: A modular tray for an ampoule of a delivery system of solid precursor materials used in Atomic Layer Deposition (ALD) processes, Chemical Vapor Deposition (CVD) processes or both. The modular tray is configured with separate components which can enhance the ease of which the modular tray can be inserted into the ampoule, and the tray is configured to make improved contact with inner wall surfaces of the ampoule to provide improved heat transfer from the inner wall to the modular tray and ultimately to the solid precursor materials disposed on the modular tray.

  • Publication number: 20230115177
    Abstract: A tray for an ampoule of a delivery system of solid precursor materials used in Atomic Layer Deposition (ALD) processes, Chemical Vapor Deposition (CVD) processes or both. The tray is configured to be able to have a reduced profile size when compressed to enhance the ease of which the tray can be inserted into the ampoule, and the tray is configured to expand in size to make improved contact with inner wall surfaces of the ampoule to provide improved heat transfer from the inner wall to the tray and ultimately to the solid precursor materials disposed on the tray.

  • Publication number: 20210123134
    Abstract: A solids delivery ampule includes an ampule body defining an interior space. The interior space contains one or more solids support, and each solids support configured to support a quantity of a sublimation solid. The solids delivery ampule also includes a vapor outlet ports, one or more level sensor ports, and one or more level sensors. Each of the one or more level sensors extending through the one or more level sensor port into the interior space. Each of the one or more level sensors measures the quantity of the sublimation solid in each solids support.

  • Patent number: 10895010
    Abstract: Apparatus and method for volatilizing a source reagent susceptible to particle generation or presence of particles in the corresponding source reagent vapor, in which such particle generation or presence is suppressed by structural or processing features of the vapor generation system. Such apparatus and method are applicable to liquid and solid source reagents, particularly solid source reagents such as metal halides, e.g., hafnium chloride. The source reagent in one specific implementation is constituted by a porous monolithic bulk form of the source reagent material. The apparatus and method of the invention are usefully employed to provide source reagent vapor for applications such as atomic layer deposition (ALD) and ion implantation.

  • Patent number: 10895347
    Abstract: The invention is directed to a vaporizer or ampoule assembly with improved heat transfer between a vaporizer vessel body and at least one support tray located therein. In particular, there is provided a heat transfer enhancing member that is disposed between a vessel body and support tray. In one example of a heat transfer enhancing member or assembly there is included a heat conductive mesh or liner around totally or partially around the support tray that is wedged in between the support tray and the interior diameter or wall of the vessel body. In a related embodiment, the heat transfer enhancing member includes an expandable support tray sidewall to increase physical contact between the support tray and the vessel body interior wall.

  • Patent number: 10465286
    Abstract: Vaporizable material is supported within a vessel to promote contact of an introduced gas with the vaporizable material, and produce a product gas including vaporized material. A heating element supplies heat to a wall of the vessel to heat vaporizable material disposed therein. The vessel may include an ampoule having a removable top. Multiple containers defining multiple material support surfaces may be stacked disposed within a vessel in thermal communication with the vessel. A tube may be disposed within the vessel and coupled to a gas inlet. Filters, flow meters, and level sensors may be further provided. Product gas resulting from contact of introduced gas with vaporized material may be delivered to atomic layer deposition (ALD) or similar process equipment. At least a portion of source material including a solid may be dissolved in a solvent, followed by removal of solvent to yield source material (e.g., a metal complex) disposed within the vaporizer.

  • Patent number: 10385452
    Abstract: Systems, reagent support trays, particle suppression devices, and methods are disclosed. In one aspect, a system includes a vaporizer vessel having one or more interior walls enclosing an interior volume and a plurality of reagent support trays configured to be vertically stackable within the interior volume. Each of the plurality of reagent support trays is configured to be vertically stackable within the interior volume to form a stack of reagent support trays. One or more of the plurality of reagent support trays is configured to redirect a flow of a gas passing between adjacent reagent support trays in the stack of reagent support trays to cause the flow of gas to interact with the source reagent material in a particular reagent support tray before passing into a next of the plurality of reagent support trays in the stack of reagent support trays.
