Patent ID: 7102748

Claim:
A lithographic apparatus configured to expose devices on a substrate, the apparatus comprising: a radiation system configured to provide a beam of radiation; a support structure configured to support patterning structure, the patterning structure serving to pattern the beam of radiation according to a desired pattern; a substrate table configured to hold said substrate; a projection system configured to project the patterned beam onto a target portion of the substrate; and a control system configured to control said lithographic apparatus to perform exposures, each exposure comprising a plurality of operations, wherein said control system is configured to control said lithographic apparatus to operate at a desired throughput rate, and wherein, for at least one of said plurality of operations, said control system is configured to allot a corresponding period of time to execution of the operation, and wherein, when said desired throughput rate is lower than a maximum throughput rate achievable by said lithographic apparatus, said control system is configured to increase the corresponding period of time allotted to at least one of said plurality of operations to increase the accuracy of said exposures.
