Abstract
A substrate warpage determination system comprises at least three first supporting devices and at least three second supporting devices, forming first and second substrate support areas configured to carry a substrate, an actuator configured to move the at least three second supporting devices in a vertical direction, and a controller to drive the actuator. The controller is configured to determine a force exerted by the actuator, compare the determined force exerted by the actuator at the position in a vertical direction of the second substrate support area relative to the first substrate support area to a predetermined force at a predetermined position in the vertical direction of the second substrate support area relative to the first substrate support area, and determine a warpage of the substrate from the comparison.
