  • Patent number: 10225495
    Abstract: A crosstalk processing module configured to process a crosstalk of an image signal includes a correction element generation unit, a storage, and a crosstalk correction check unit. The correction element generation unit receives the image signal and input information associated with at least a size of the image signal and generates seed values and correction parameters which are used to correct the crosstalk, based on the input information and a representative channel image signal obtained by separating the image signal with respect to color. The storage stores the seed values and the correction parameters. The crosstalk correction check unit receives the image signal, receives the seed values and the correction parameters from the storage, corrects the crosstalk, and outputs a final image signal and pass/fail information indicating a pass or fail of the correction of the crosstalk based on a plurality of reference values.

  • Patent number: 7985297
    Abstract: A cleaning solution for a quartz part and a method for cleaning the quartz part are provided. The cleaning solution includes from about 5 to about 35 wt % of an ammonium compound, from about 7 to about 55 wt % of an acidic oxidizing agent, from about 5 to about 30 wt % of a fluorine compound and a remaining amount of water. Residual thin films and impurities on the surface of the quartz part may be removed while reducing the damage onto the quartz part.

  • Publication number: 20110130000
    Abstract: A method of manufacturing a semiconductor device includes preparing a substrate on which a fuze line containing copper is formed. The method further includes cutting the fuze line by emitting a laser beam, and applying a composition for etching copper to the substrate to finely etch a cutting area of the fuze line and to substantially remove at least one of a copper residue and a copper oxide residue remaining near the cutting area. The composition for etching copper includes about 0.01 to about 10 percent by weight of an organic acid, about 0.01 to 1.0 percent by weight of an oxidizing agent, and a protic solvent.
