摘要： An electron beam inspection system of the image projection type includes a primary electron optical system for shaping an electron beam emitted from an electron gun into a rectangular configuration and applying the shaped electron beam to a sample surface to be inspected. A secondary electron optical system converges secondary electrons emitted from the sample. A detector converts the converged secondary electrons into an optical image through a fluorescent screen and focuses the image to a line sensor. A controller controls the charge transfer time of the line sensor at which the picked-up line image is transferred between each pair of adjacent pixel rows provided in the line sensor in association with the moving speed of a stage for moving the sample.

摘要： A system for further enhancing speed, i.e. improving throughput in a SEM-type inspection apparatus is provided. An inspection apparatus for inspecting a surface of a substrate produces a crossover from electrons emitted from an electron beam source 25•1, then forms an image under a desired magnification in the direction of a sample W to produce a crossover. When the crossover is passed, electrons as noises are removed from the crossover with an aperture, an adjustment is made so that the crossover becomes a parallel electron beam to irradiate the substrate in a desired sectional form. The electron beam is produced such that the unevenness of illuminance is 10% or less. Electrons emitted from the sample W are detected by a detector 25•11.

摘要： A sample is evaluated at a high throughput by reducing axial chromatic aberration and increasing the transmittance of secondary electrons. Electron beams emitted from an electron gun 1 are irradiated onto a sample 7 through a primary electro-optical system, and electrons consequently emitted from the sample are detected by a detector 12 through a secondary electro-optical system. A Wien filter 8 comprising a multi-pole lens for correcting axial chromatic aberration is disposed between a magnification lens 10 in the secondary electro-optical system and a beam separator 5 for separating a primary electron beam and a secondary electron beam, for correcting axial chromatic aberration caused by an objective lens 14 which comprises an electromagnetic lens having a magnetic gap defined on a sample side.
