    Abstract: A measurement method capable of easily measuring the directions of detector segments of a segmented detector relative to a scanning transmission electron microscope (STEM) image is provided. The measurement method is for use in an electron microscope equipped with the segmented detector having a detection surface divided into the detector segments. The measurement method is used to measure the directions of the detector segments relative to the STEM image. The method involves defocusing the STEM image to thereby cause a deviation of the STEM image and measuring the directions of the detector segments relative to the STEM image from the direction of the deviation of the STEM image (step S11).

The charged particle system (100) has: illumination optics (104) for illuminating the sample with charged particles; an imaging deflector system (112) disposed behind an objective lens (110) and operative to deflect the charged particles; a detector (116) having a detection surface (115) and operative to detect the charged particles incident thereon, imaging optics (114) disposed behind the imaging deflector system (112) and operative to focus the charged particles as diffraction discs (2) onto the detection surface (115); a storage unit (120) for storing intensity information detected by the detector (116); and a controller (130) for controlling the imaging deflector system (112). The controller (130) controls the imaging deflector system (112) to cause the charged particles passing through a given position of particle impingement on the sample to be deflected under successively different sets of deflection conditions and to bring the diffraction discs (2) into focus onto successively different regions of the detection surface (115). The storage unit (120) stores the intensity information for each set of the deflection conditions.

    Abstract: The present invention relates to a defect inspection apparatus based on the fact that contrasts of a grain and a void of a semiconductor copper interconnect in a scanning electron microscope are changed depending on electron beam irradiation accelerating voltages. A charged particle beam apparatus of the present invention irradiates the same portion of a specimen with electron beams at a plurality of accelerating voltages, and differentiates a grain (65, 66) from a void (67) on the basis of a contrast change amount of the same portion in a plurality of images (61, 62) acquired so as to respectively correspond to the plurality of accelerating voltages. Consequently, it is possible to automatically detect a grain and a void in a differentiation manner at a high speed without destructing a specimen.

    Abstract: The present invention provides means and corresponding embodiments to control charge-up in an electron beam apparatus, which can eliminate the positive charges soon after being generated on the sample surface within a frame cycle of imaging scanning. The means are to let some or all of secondary electrons emitted from the sample surface return back to neutralize positive charges built up thereon so as to reach a charge balance within a limited time period. The embodiments use control electrodes to generate retarding fields to reflect some of secondary electrons with low kinetic energies back to the sample surface.

    Abstract: In a method for imaging a solid state substrate, a vapor is condensed to an amorphous solid water condensate layer on a surface of a solid state substrate. Then an image of at least a portion of the substrate surface is produced by scanning an electron beam along the substrate surface through the water condensate layer. The water condensate layer integrity is maintained during electron beam scanning to prevent electron-beam contamination from reaching the substrate during electron beam scanning. Then one or more regions of the layer can be locally removed by directing an electron beam at the regions. A material layer can be deposited on top of the water condensate layer and any substrate surface exposed at the one or more regions, and the water condensate layer and regions of the material layer on top of the layer can be removed, leaving a patterned material layer on the substrate.
