摘要： An exemplary a charged particle beam apparatus converts an inspection position on a test sample (wafer coordinate system) to a setting position of an inspection mechanism (stage coordinate system (polar coordinate system)), a rotating arm and a rotating stage being rotated to be moved for the inspection position on the test sample. In this case, inspection devices are arranged over a locus that is drawn by the center of the rotating stage according to the rotation of the rotating arm. A function for calculating errors (e.g., center shift of the rotating stage) and compensating for the errors is provided, by which the precision of inspection is improved in a charged particle beam apparatus equipped with a biaxial rotating stage mechanism.

摘要： The invention relates to a trajectory correction method for a charged particle beam, and provides a low-cost, high accuracy and high-resolution converging optical system for use with a charged particle beam to solve problems with conventional aberration correction systems. To this end, the present invention uses a configuration which forms electromagnetic field which is concentrated towards a center of a beam trajectory axis, causes oblique of the beam to make use of lens effects and bend the trajectory, and consequently, cancels out large external side non-linear effects such a spherical aberration of the electron lens. Specifically, the configuration generates an electric field concentration in a simple manner by providing electrodes above the axis and applying voltages to the electrodes. Further, the above configuration can be realized trough operations using lenses and deflectors with incident axes and image formation positions that are normal.
