  • Patent number: 11953839
    Abstract: In a method of cleaning a lithography system, during idle mode, a stream of air is directed, through a first opening, into a chamber of a wafer table of an EUV lithography system. One or more particles is extracted by the directed stream of air from surfaces of one or more wafer chucks in the chamber of the wafer table. The stream of air and the extracted one or more particle are drawn, through a second opening, out of the chamber of the wafer table.

  • Publication number: 20130067142
    Abstract: A method of judging problem storage regions adapted for a flash memory storage device includes steps of: sending a writing order to a flash memory chip for writing a written data to an appointed storage paging; when the flash memory chip beginning writing the written data to the appointed storage paging, getting the first time; when the flash memory chip finishing writing the written data to the appointed storage paging, getting the second time; calculating a writing time according to the first time and the second time; if the writing time not coincident with a standard value, then labeling the appointed storage paging as a problem storage region and copying the written data to a backup paging; updating a Mapping Table.

  • Patent number: 7317632
    Abstract: A non-volatile memory storage device with functions of boosting supply voltage and signal level can adopt a non-volatile memory having an operating voltage higher than the supply voltage provided by the host device as a storage medium. The non-volatile memory storage device includes a supply voltage booster, a non-volatile memory storage unit and a controller. The supply voltage booster boosts the lower supply voltage provided by the host device up to the higher operating voltage of the non-volatile memory. The controller adjusts the interface signal to a proper interface signal level by cooperating with the supply voltage and the operating voltage so as to avoid the interface from damage owing to an over high signal level or avoid the non-volatile memory unit from not correctly receiving signal due to an over low signal level.

  • Publication number: 20070220254
    Abstract: A secure digital memory device comprising a first memory chip, a second memory chip, and a controller. The controller is coupled to the first and second memory chips and operates in an automatic backup mode of the secure digital memory device. In the automatic backup mode, the controller configures the first and second memory chips as main and backup memory partitions respectively. When data is written into the secure digital memory device, the controller writes the data to the main memory partition and into the backup memory partition to serve as backup data.
