Abstract:
Disclosed is a stage system and metrology apparatus comprising at least one such stage system. The stage system comprises a stage carrier for holding an object and a stage carrier positioning actuator for displacing the stage carrier. The stage system also comprises a balance mass to counteract a displacement of the stage carrier, and a balance mass positioning actuator for displacing the balance mass. A cable arrangement is connected to the stage carrier for the supply of at least power to said stage carrier. The stage system is operable to apply a compensatory feed-forward force to the balance mass which compensates for a cable arrangement force exerted by the cable arrangement.

Claim (Index 22):
A metrology tool operable to measure a parameter of a substrate, comprising a frame and a stage system mounted to the frame, wherein the stage systems comprises:\n a stage carrier configured to hold an object; a stage carrier positioning actuator configured to displace the stage carrier; a balance mass configured to compensate for a displacement the stage carrier; a balance mass positioning actuator configured to displace the balance mass; and a cable arrangement connected between the stage carrier and the frame and configured to supply at least power to the stage carrier; wherein the stage system are operable to apply a compensatory feed-forward force to the balance mass which compensates for a cable arrangement force exerted by the cable arrangement.
