  • Patent number: 10249474
    Abstract: The scanning charged particle beam microscope according to the present application is characterized in that, in acquiring an image of the FOV (field of view), interspaced beam irradiation points are set, and then, a deflector is controlled so that a charged particle beam scan is performed faster when the charged particle beam irradiates a position on the sample between each of the irradiation points than when the charged particle beam irradiates a position on the sample corresponding to each of the irradiation points (a position on the sample corresponding to each pixel detecting a signal). This allows the effects from a micro-domain electrification occurring within the FOV to be mitigated or controlled.

  • Patent number: 10115636
    Abstract: A workpiece has a plurality of low-dielectric-constant insulation films and a metallic pattern stacked on a surface of a semiconductor substrate. Devices are formed in a plurality of regions partitioned by streets formed in a grid pattern. Surfaces of the devices formed on the workpiece are covered with a surface protective member, leaving the streets exposed. A dispersion of abrasive grains in an etching liquid capable of dissolving the metallic pattern is blasted against the workpiece together with compressed gas so as to remove the low-dielectric-constant insulation films and the metallic pattern on the streets, thereby exposing the semiconductor substrate. The workpiece is divided with the semiconductor substrate exposed by the wet blasting step subjected to dry etching so as to divide the workpiece along the streets.
