  • Publication number: 20220139761
    Abstract: A load lock device includes a load lock chamber, and a substrate holding structure configured to hold a substrate in the load lock chamber, wherein the substrate holding structure includes a facing surface facing the substrate, and is configured to allow a gas to flow through a space between the substrate and the facing surface, and in a state in which the substrate is held by the substrate holding structure, a distance between the substrate and a portion located inside an outer edge of the facing surface is larger than a distance between the substrate and the outer edge of the facing surface.

  • Patent number: 10062553
    Abstract: A sputtering apparatus includes a space defining member defining a sputtering space for forming a film on a substrate. The space defining member includes a concave portion, and an opening portion is provided in the bottom portion of the concave portion. The sputtering apparatus includes a shield member configured to shield the opening portion from the sputtering space. The opening portion is formed so that a pressure gauge capable of measuring the pressure in the sputtering space can be attached, and the shield member is arranged so that at least a part of the shield member is buried in the concave portion.
