  • Patent number: 8330103
    Abstract: In a multi-charged-particle-beam apparatus, when an electric field and voltage on a surface of a specimen are varied according to characteristics of the specimen, a layout of plural primary beams on the surface of the specimen and a layout of plural secondary beams on each detector vary. Then, calibration is executed to adjust the primary beams on the surface of the specimen to an ideal layout corresponding to the variation of operating conditions including inspecting conditions such as an electric field on the surface and voltage applied to the specimen. The layout of the primary beams on the surface of the specimen is acquired as images displayed on a display of reference marks on the stage. Variance with an ideal state of the reference marks is measured based upon these images and is corrected by the adjustment of a primary electron optics system and others.

  • Patent number: 8331153
    Abstract: In a nonvolatile memory apparatus, a system bus receives address, command, and/or control signals. Memory cells store bits of data by shifting a threshold voltage to one of plural ranges. In writing a first page, the threshold voltage of a first memory cell remains in a first range or shifts into a second range. In writing a second page, the threshold voltage remains in the first or second voltages, or shifts into a third range from the first range or into a fourth range from the second range. Before writing the second page, the memory reads data from the first memory cell for generating the second page writing data. A shifting direction of the threshold voltage from the first to the second range is the same as a shifting direction from the first to the third range.
