  • Patent number: 10636620
    Abstract: By switching between a plurality of image transfer units based on a state of a stage and using the switched image transfer unit, traceability of stage movement and tolerance to communication failure can be improved. A first image transfer protocol is a protocol of which reliability is higher than reliability of a second image transfer protocol, and a switch unit may select a first image transfer unit in a case where it is determined that a state of a stage is a state in which the stage is stopping. A second image transfer unit is a protocol of which a transfer speed is higher than a transfer speed of the first image transfer protocol, and the switch unit may select the second image transfer unit in a case where it is determined that the state of the stage is a state in which the stage is moving.

  • Patent number: 7916926
    Abstract: An inspected image can be communicated without putting large load on a network. A remote console enables an operation screen and a moving image to be displayed and processed without color shifts. Information on the operation screen is not communicated as bitmap information, but event information such as a formation of a window and the moving of a mouse is communicated as information at a level of I parts of graphical user interface. Moreover, communication of the event information on the operation screen and communication of a moving image are separated. In addition, a method of compressing information on the operation screen and a method of compressing information on the moving image are separated. A necessary part of information on the moving image is selected and communicated depending on the state of the semiconductor inspection apparatus, an operation of an operator, and a pattern to be inspected.
