  • Publication number: 20250324487
    Abstract: Disclosed are a jig device for attachment and detachment of a heater unit, a system for attachment and detachment of the heater unit, and a high-pressure annealing device capable of attaching and detaching the heater unit thereto and therefrom. The heater unit is attachable to or detachable from the high-pressure annealing device through upward movement or downward movement of the heater unit from or toward the lower portion of an outer chamber in a state in which the heater unit disposed in the high-pressure annealing device is supported by the jig device.
