Abstract
The substrate processing apparatus includes a suction holding mechanism, a rotation mechanism, a plurality of lift pins, a vertical movement mechanism, and a horizontal movement mechanism. The suction holding mechanism sucks and holds a substrate. The rotation mechanism rotates the suction holding mechanism holding the substrate about the rotation axis. The vertical movement mechanism moves the plurality of lift pins in the vertical direction. A sensor measures the eccentric state of the substrate W held by the suction holding mechanism. The vertical movement mechanism supports the substrate from the suction holding mechanism by moving the plurality of lift pins and the horizontal movement mechanism moves the plurality of lift pins based on the eccentric state of the substrate measured by the sensor in a state where the substrate is supported.
