  • Patent number: 10090058
    Abstract: A semiconductor device may be provided. The semiconductor device may be configured for detecting a defect of a fuse set. The semiconductor device may include a pseudo initial signal generator configured to generate pseudo initial information on the basis of a test mode signal. The semiconductor device may include a fuse-set defect detector configured to compare fuse-set information of a fuse set or the pseudo initial information with a reference value on the basis of a fuse-set address, and detect a defect of the fuse set.
    Type: Grant

  • Publication number: 20070110922
    Abstract: A method of forming the alignment film includes placing an inorganic target and a substrate in a chamber so that the inorganic target and the substrate are parallel to each other, evacuating the chamber to a first pressure, supplying a discharge gas into the chamber and evacuating the chamber to a second pressure higher than the first pressure. Moreover, the method further includes depositing an inorganic film on the substrate by ejecting inorganic particles from the inorganic target.
