摘要： A method of controlling output of a radiation source, the method including: periodically monitoring an output energy of the radiation source; determining a difference between a reference energy signal and the monitored output energy; determining a feedback value; determining a desired output energy of the radiation source for a subsequent time period; and controlling an input parameter of the radiation source in dependence on the determined desired output energy during the subsequent time period. If the magnitude of the determined difference between the monitored output energy of the radiation source and the reference energy signal exceeds a threshold value: the determined difference does not contribute to the feedback value; and the determined difference is spread over the subsequent time period according to a reference energy signal adjustment profile and the reference energy signal adjustment profile is added to the reference energy signal for the subsequent time period.

摘要： A lithographic apparatus comprises: a radiation system (SO, IL, BD); a frame (BF, MF); a substrate table (WT) for holding a substrate (W); a scanning mechanism (PW). The radiation system is operable to produce a radiation beam (PB). The substrate table is moveably mounted to the frame and arranged such that a target portion of the substrate is arranged to receive the radiation beam. The scanning mechanism is operable to move the substrate table relative to the frame so that different portions of the substrate may receive the radiation beam. A mechanism (AC) is operable to determine a quantity indicative of a velocity of the radiation system relative to the frame. An adjustment mechanism is operable to control a power or irradiance of the radiation beam so as to reduce a variation in a dose of radiation received by the substrate as a result of relative motion of the radiation system and the frame.
