    摘要: A lithographic apparatus includes apparatus for measuring the alignment of an object. The measuring apparatus includes a plurality of alignment sensors, each including an alignment detector for measuring the position of an alignment mark over an alignment detection area. The measuring apparatus further includes a leveling sensor for measuring the height and/or tilt of an object in a leveling sensor detection area, and a feed-forward connection between said leveling sensor and said alignment sensors.
