  • Publication number: 20260042130
    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.

  • Publication number: 20230234014
    Abstract: A source vessel weight monitoring assembly for use in reactor systems to provide real-time and direct measurements of the availability of source or process 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 the source vessel and a support element for the vessel (e.g., a base of a source vessel enclosure). The sensors are positioned to at least partially support the vessel, and 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 the source vessel and process material (e.g., solid, liquid, or gaseous precursor) stored therein. The controller uses this weight to calculate the amount of available process material or chemistry in the source vessel.

  • Publication number: 20230203654
    Abstract: Apparatus and method for semiconductor substrate processing are presented. For devices such as valves used for semiconductor substrate processing especially a process like ALD, there is a need to monitor and control the exact time taken from the signal to open and close the valves so that delay times may be controlled. In an embodiment, an apparatus comprising a reactor, a valve, a process controller and a valve monitor system is presented. The process controller may be operationally connected to the valve and may be provided with a memory. The sensors may be either electrical or optical sensors.

The delivery system can include a vapor deposition reactor, two or more bulk fill vessels remote from the vapor deposition reactor, an interconnect line, a line heater, and a gas panel comprising one or more valves. Each bulk fill vessel is configured to hold solid source chemical reactant therein. The bulk fill vessels can each include fluid outlets. The interconnect line can fluidly connect the vapor deposition reactor with each bulk fill vessel. The line heater can heat at least a portion of the interconnect line to at least a minimum line temperature. The one or more valves of the gas panel can switch a flow of vaporized chemical reactant through the interconnect line from being from one fluid outlet to being from another fluid outlet.
