    摘要: A charged particle beam apparatus can be constructed with a smaller size (resulting in a small installation space) and a lower cost, suppress vibration, operate at higher speed, and be reliable in inspection. The charged particle beam apparatus is largely effective when a wafer having a large diameter is used. The charged particle beam apparatus includes: a plurality of inspection mechanisms, each of which is mounted on a vacuum chamber and has a charged particle beam mechanism for performing at least an inspection on the sample; a single-shaft transfer mechanism that moves the sample between the inspection mechanisms in the direction of an axis of the single-shaft transfer mechanism; and a rotary stage that mounts the sample thereon and has a rotational axis on the single-shaft transfer mechanism. The single-shaft transfer mechanism moves the sample between the inspection mechanisms in order that the sample is placed under any of the inspection mechanisms. The rotary stage positions the sample such that a target portion of the sample can be inspected by the inspection mechanism under which the sample is placed, and the inspection mechanisms inspect the sample.

    摘要: When conditions for an electron gun mainly represented by extraction voltage V1 and accelerating voltage V0 are changed, a charged particle beam is once focused on a fixed position by means of a condenser lens and a virtual cathode position is calculated from a lens excitation of the condenser lens at that time and the mechanical positional relation of the electron gun to set an optical condition. For more accurate setting of the optical condition, a deflecting electrode device is provided at a crossover position of the condenser lens and a voltage is applied to the deflecting electrode device at a constant period so as to control the lens excitation of the condenser lens such that the amount of movement of an image is minimized on an image display unit such as CRT.

    摘要: An apparatus for inspecting a sample using a scanning electron microscope includes a sample stage, a first electron-optical system to scan an electron beam of a first beam current on the sample, a second electron-optical system to scan an electron beam of a second beam current smaller than the first beam current on the sample, a mechanism to move the sample stage, a detector provided in each of the first and second electron-optical systems to detect a secondary electron. The first electron-optical system is operable in a first mode and the second electron-optical system is operable in a second mode with higher resolution than that of the first mode. In the first mode, the sample is observed while the sample stage is moved continuously, and in the second mode, the sample is observed by detecting a secondary electron using the detector while the sample stage is held stationary.

    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.

    摘要: A lip categorizing method uses the size and shape of the lips as viewed from the front of the face as a first categorization index and the three-dimensional form of the lips as a second categorization index. The lip categorizing map is composed of a first coordinate axis showing the degree of the first categorization index and a second coordinate axis showing the degree of the second categorization index and has a coordinate system in which the first and second coordinate axes are orthogonal. It also generates makeup information for two-dimensionally correcting the lips of a subject based on preset reference by setting a plurality of points for determining the form features of lips on an image that depicts the lips, and judges the form features of the lips of the subject based on analytical values of the two-dimensional features of the lips measured from the set points.
