    Abstract: In a substrate support according to one exemplary embodiment, an adhesive is provided between an upper surface of a base and a lower surface of the electrostatic chuck. The base, the adhesive, and the electrostatic chuck provide a supply path for supplying a heat transfer gas between the electrostatic chuck and a substrate. The upper surface of the base defines one or more grooves. The one or more grooves are further away from a center of the upper surface than the supply path. The adhesive is provided to cover an upper end opening of each of the one or more grooves. The heat transfer gas is capable of being supplied to the one or more grooves via the supply path or a different flow path. The substrate support further includes a pressure sensor to measure pressure in the one or more grooves.

    Abstract: An air cylinder includes a cylinder, a piston rod, a piston, and a controller. The piston rod has one end disposed in the cylinder and the other end protruding from the cylinder. The piston is provided at the one end of the piston rod and moves the piston rod by moving in the cylinder. The controller supplies gas into one of a space, which is a space in the cylinder directed on the piston rod side with respect to the piston, and a space, which is a space in the cylinder opposite to the space with respect to the piston, and sucks gas from an interior of the other of the spaces.
