More Information
Summary:A system for deep ultraviolet (DUV) optical lithography includes an optical source apparatus including N optical oscillators, N being an integer number greater than or equal to two, and each of the N optical oscillators is configured to produce a pulse of light in response to an excitation signal; and a control system coupled to the optical source apparatus. The control system is configured to determine a corrected excitation signal for a first one of the N optical oscillators based on an input signal, the input signal including an energy property of a pulse of light produced by another one of the N optical oscillators.
