Abstract: There is a mounting pad for placing an object, comprising: a base; and an annular outer edge portion that is provided on one surface of the base, projects in a direction intersecting a surface direction of said one surface to surround an outer edge of said one surface, and is to be in contact with the object, wherein a thickness of the outer edge portion in at least one portion of the outer edge portion is different from a thickness of the outer edge portion in the other portions of outer edge portion.

Abstract: A substrate processing system includes a vacuum transfer module, a substrate processing module, an atmospheric transfer module, a load-lock module, at least one substrate transfer robot disposed in the vacuum transfer module and the atmospheric transfer module, and having at least one end effector, and a controller configured to control a particle removal operation. The particle removal operation includes transferring said at least one end effector in any one of the vacuum transfer module, the substrate processing module, the load-lock module, and the atmospheric transfer module in a state where at least one charging member that is charged is placed on said at least one end effector.

Abstract: A substrate processing system is disclosed, comprising: a vacuum transfer module; a substrate processing module connected to the vacuum transfer module and configured to process a substrate in a depressurized environment; a load-lock module connected to the vacuum transfer module; at least one substrate cooling stage disposed in the load-lock module; at least one substrate transfer robot disposed the vacuum transfer module and having at least one end effector; and a controller configured to control a particle removal operation. The operation includes: cooling at least one dummy substrate placed on said at least one substrate cooling stage to a first temperature; and holding said at least one end effector in any one of a plurality of positions in the vacuum transfer module or the substrate processing module for a first time period in a state where at least one cooled dummy substrate is placed on said at least one end effector.

Abstract: A substrate processing apparatus is disclosed. The apparatus comprises a vacuum transfer chamber including a top surface, a bottom surface, and side surfaces between the top and the bottom surfaces, including a first side surface and a second side surface opposite to the first side surface; a transfer robot, disposed in the vacuum transfer chamber, for transfering a substrate; a load lock module connected to the first side surface; a pipe, connected to a purge gas supply source, for supplying a purge gas into the vacuum transfer chamber; one or more gas ports provided in the top surface in the vicinity of the second side surface and connected to the pipe; and one or more exhaust ports, provided in the bottom surface in the vicinity of the first side surface, to which an exhaust pump for exhausting the purge gas supplied into the vacuum transfer chamber is connected.
