Abstract

A substrate processing apparatus includes a rotary table configured to move each of multiple substrate chucks to, in sequence, a carry-in position where a carry-in of a substrate is performed, a processing position where thinning of the substrate is performed, and a carry-out position where a carry-out of the substrate is performed; a tilt angle adjusting device configured to adjust a tilt angle of the substrate chuck with respect to the rotary table at the processing position; and a tilt angle controller configured to control the tilt angle adjusting device based on a measurement result of a plate thickness measuring device. The plate thickness measuring device measures a plate thickness of the substrate at the carry-out position.
