Abstract: A semiconductor wafer position display system, a semiconductor wafer position display method, and a semiconductor wafer position display program with which a deviation from an appropriate placement position of a semiconductor wafer mounted in a wafer mounting part can be displayed to a user in an easily understood manner are provided.

Abstract: There are provided a susceptor having a recessed wafer mounting section, in which a semiconductor wafer is mounted and which is configured to include a circular bottom portion and a side wall portion, on an upper surface, a reaction chamber in which the susceptor is provided, an imaging unit that is provided above the reaction chamber and images the semiconductor wafer and the wafer mounting section, and an image analysis unit that analyzes the deviation of the semiconductor wafer from the wafer mounting section on the basis of an image captured by the imaging unit.

Abstract: A susceptor device includes: a placement section on which a substrate is placed; a lift pin which is provided in the placement section and protrudes further to the upper side than the placement section at the time of carrying-in or carrying-out of the substrate, thereby supporting the substrate placed on the placement section; and lift pin moving means for moving the lift pin up and down. At the time of carrying-in or carrying-out of the substrate, the substrate is moved up and down by moving the lift pin up and down by the lift pin moving means in a state where the substrate is supported by the lift pin, and the susceptor device further includes a control section which controls the lift pin moving means so as to reduce a movement speed immediately before the substrate and the lift pin come into contact with each other, in a case of moving the lift pin.
