Abstract: PROBLEM TO BE SOLVED: To provide an additional technology for reducing and/or increasing a lens-heating action. SOLUTION: In the lithographic apparatus, a control system is provided so as to automatically reduce throughput of device manufacture when aberration of lens-heating exceeds a specific threshold value. Determination whether the aberration of lens-heating exceeds the threshold value, is obtained by, for example, prediction using a lens-heating model or measurement of a previously exposed substrate. Reduction of the throughput can be achieved by reducing beam power or duty-cycle of the apparatus. In a specific embodiment, time required for substrate transfer between exposed portions is increased. COPYRIGHT: (C)2010,JPO&INPIT
