  • 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.

  • Method for adjusting a front-side bus frequency based on a processor usage rate stored in a translation table and generating the translation table if it does not exist
    Patent number: 7296169
    Abstract: A method for dynamically adjusting central processing unit (CPU) frequency. Firstly, a translation table is provided between multi-layer of CPU usage percentage and front-side bus operation frequency. Secondly, a current usage percentage of the CPU is obtained. Lastly, the operation frequency of the front-side bus is adjusted to a corresponding layer according to the current usage rage, so that the current usage rage is located within the range of CPU usage percentage that is defined by corresponding layer.
