More Information
Summary:A system includes a wafer stage adapted to hold a semiconductor wafer thereon. A moveable temperature sensor array is configured to move to a plurality of different positions over a surface of the wafer stage and to take a plurality of temperature measurements at the plurality of positions, respectively. Based on the plurality of temperature measurements, a controller is adapted to determine an expected thermal deformation for the semiconductor wafer or for a reticle arranged over the semiconductor wafer.
