The basic principle and application of high-voltage pulse power supply are briefly described, the principle and characteristics of all-solid-state high-voltage pulse power supply are introduced. The history of semiconductor lithography and the need for excimer lasers as light sources in semiconductor lithography are reviewed. The application of all-solid-state high-voltage pulse power supply in excimer laser for lithography is emphasized. The high-power semiconductor switch combined with multi-stage magnetic pulse compression switch is used to replace the traditional thyristor-based high-voltage pulse power supply, and a long life operation of the excimer laser at a high repetition rate is achieved. The progress of the research on the all-solid-state high-voltage pulse power supply of excimer lasers in the past ten years of Anhui Institute of Optics and Fine Mechanics of Chinese Academy of Sciences is also introduced.
