  • Publication number: 20250053104
    Abstract: Particulate deposition rate on a photolithographic mask, particularly of tin (Sn) particles produced within an EUV light source, is reduced by producing turbulence within a radiation source chamber of the EUV light source. Turbulence can be produced by changing the temperature, pressure, and/or gas flow rate within the radiation source chamber. The turbulence reduces the number of particles exiting the EUV light source which could be deposited on the photomask.

Next, the control circuit controls the second switch to be ON for a synchronous rectification time period. Next, the control circuit controls the first and second switches to be OFF for a second dead time period. Next, the control circuit controls the second switch to be ON for a zero-voltage-switching pulse time period. Next, the control circuit controls the first and second switches to be OFF for a third dead time period. By the above operations, the first switch achieves soft switching.
