Abstract
A method, system, and apparatus for management of reaction loads in a lithography system is described. An isolated structure is supported by a non-isolated structure. The isolated structure supports a moveable stage. A linear motor includes a first linear motor element and a second linear motor element. The first linear motor element is coupled to the moveable stage. A plurality of parallel flexure plates mount the second linear motor element on the isolated structure. A flexure rod is coupled between the non-isolated structure and the second linear motor element.
