  • EUV photolithography system fuel source and methods of operating the same
    Patent number: 12235586
    Abstract: Impurities in a liquefied solid fuel utilized in a droplet generator of an extreme ultraviolet photolithography system are removed from vessels containing the liquefied solid fuel. Removal of the impurities increases the stability and predictability of droplet formation which positively impacts wafer yield and droplet generator lifetime.
