Abstract: A lithographic workpiece processing tool includes a loading area for loading a workpiece; and a processing area for processing a workpiece. The workpiece processing tool further includes a multi-table system arranged between the loading area and the processing area. The multi-table system includes at least two tables configured to pass each other while moving between the loading area and the processing area. Each of the at least two tables is configured to hold a workpiece.

Abstract: A pattern generation system includes an optical system and a rotor. The optical system is configured to project a laser image onto an optical scanner. The rotor has a plurality of optical arms arranged at a first angle relative to one another, and further includes the optical scanner. The laser image is sequentially reflected by the optical scanner into each of the plurality of optical arms of the rotor to generate a pattern on a workpiece.

Abstract: In a measurement device for measuring a peripheral position in a Cartesian coordinate system, a rotating laser source is configured to emit a laser beam along a radius of a rotator. A reflector is configured to reflect the laser beam in a direction orthogonal to a path of the laser beam, and a scale having a pattern of transparent and reflective areas is positioned at a peripheral position of the measurement device. A detector is configured to provide a sequence of pulses by detecting a reflex or transmission of the rotating laser beam while the laser scans over the scale. The sequence of pulses correspond to Cartesian coordinates of the system.
