摘要: A method for calibrating an auxiliary sensor system is provided. The auxiliary sensor system measures a position of a grating relative to a reference, the grating forming part of an encoder measurement system. The encoder measurement system is adapted to measure a position of a substrate table of a lithographic apparatus and further comprises a sensor mounted to the substrate table. The method comprises exciting the grating to make a movement in at least one measurement direction of the auxiliary sensor system, obtaining an auxiliary sensor system output signal from the sensor system during the movement, and adjusting a parameter of the auxiliary sensor system based on the output signal obtained during the movement to thereby calibrate the auxiliary sensor system.

摘要: A piezo actuator system, is presented herein. A piezo actuator system comprises a number of piezo actuators which may lengthen and shear. Using the lengthening and shearing, the piezo actuator system grips and moves an object in response to a first and a second control signal, respectively. The possible displacement of the object is limited by the maximum shear of the piezo actuators. To increase the possible displacement, the piezo actuators may be controlled to perform a linear shear sequence or a shuffle sequence. During the linear shear sequence, the object is moved; during the shuffle sequence the object is substantially stationary, while the piezo actuators are repositioned with respect to the object, after which the object may be moved further using the linear shear sequence.A piezo actuator system may be adapted to perform a slow shuffle sequence, being a relatively slowly performed shuffle sequence, during which the linear shear sequence may be performed simultaneously, preventing any dead time during movement.
