摘要:
The present invention relates to a beam output control method in which an output from a pulse energy source that emits pulses of exposure beam used in an exposure apparatus is controlled. This method controls an output from the pulse energy source by changing a control mode in accordance with an operation of the exposure apparatus. The control mode includes at least two of: a first mode in which the output from the pulse energy source is controlled based on a detection result of an energy sensor provided within the pulse energy source; a second mode in which the output from the pulse energy source is controlled based on a detection result of an energy sensor provided in the exposure apparatus; a third mode in which the output from the pulse energy source is controlled so that dispersions in the energy for each pulse of the exposure beam emitted from the pulse energy source are suppressed; and a fourth mode in which the output from the pulse energy source is controlled so that dispersions in the integrated energy of a predetermined number of pulses of the exposure beam emitted from the pulse energy source are suppressed.
