摘要: A lithographic apparatus includes an illumination system constructed and arranged to condition a radiation beam, support patterning device. The device is capable of imparting the beam with pattern in its cross-section form patterned beam. also substrate table hold substrate, projection project onto target portion substrate. chuck having plurality protrusions corresponding parts bottom surface wafer. top at least one elements that define reduced contact area between protrusion.
