ACTIVELY COMPENSATED STAGE HAVING 5-DOF MOTION ERROR COMPENSATION AND MOTION ERROR COMPENSATING METHOD THEREOF |
摘要 |
<p>Disclosed are an actively compensated stage including: a guide support having first and second guide surfaces perpendicular to each other; a table having first and second sides opposite the first and second guide surfaces and having air bearings on the first and second sides; a driving linear motor moving the table straight in an x-axial direction; and a plurality of magnetic actuators applying a magnetic preload between the guide support and the table and changing a magnetic force between the guide support and the table to compensate for 5-DOF motion errors generated in the table.</p> |
