  • Patent number: 7884334
    Abstract: The method includes scanning a sample in at least one first scan line using a first charged particle beam probe; scanning the sample in at least one second scan line using a second charged particle beam probe, and scanning the sample in at least one third scan line using the first charged particle beam probe. The first or second charged particle beam probe is defocused by a control module of the imaging system through adjusting a condenser lens module, an objective lens module, a sample stage of the imaging system, or their combination. An image of the sample is selectively formed from the first, second and third scan lines. The first and the second charged particle beams induce a first charging condition and a second charging condition on the sample surface respectively. The second charging condition can enhance, mitigate, eliminate, reverse or have no effect on the first charging condition.

  • Patent number: 7880152
    Abstract: The invention relates to a device and a method for producing resist profiled elements. According to the invention, an electron beam lithography system is used to produce an electron beam, the axis of the beam being essentially perpendicular to a resist layer in which the resist profiled element is to be produced. The electron beam can be adjusted in terms of the electron surface dose in such a way that a non-orthogonal resist profiled element can be produced as a result of the irradiation by the electron beam.

  • Patent number: 7880135
    Abstract: The analyst previously enters the mass of a fragment that desorbs in the first dissociation with other analysis conditions, as the precursor ion selection reference for the second dissociation through the input unit 25. When the automatic analysis is started, the controller unit 21 sequentially performs the MS1 analysis, MS2 analysis and MS3 analysis. In the course of these analyses, the data processing unit 23 determines the valence of each ion species corresponding to the peaks appearing in the mass spectrum obtained by the MS1 analysis. In addition, after the MS2 analysis, the data processing unit 23 searches for the ion species in conformity with the selection reference in consideration of the determined valence, among the ion species corresponding to the peaks appearing in the mass spectrum by the MS2 analysis. The selected ion is determined as the precursor ion for the second dissociation in the MS3 analysis.

  • Patent number: 7875858
    Abstract: 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.

  • Patent number: 7875850
    Abstract: The invention provides a standard component for calibration that enables a calibration position to be easily specified in order to calibrate accurately a scale factor in the electron-beam system, and provides an electron-beam system using it. The standard component for calibration is one that calibrates a scale factor of an electron-beam system based on a signal of secondary charged particles detected by irradiation of a primary electron beam on a substrate having a cross section of a superlattice of a multi-layer structure in which different materials are deposited alternately. The substrate has linear patterns on the substrate surface parallel to the multi-layers and are arranged at a fixed interval in a direction crossing the cross section of the superlattice pattern, and the cross sections of the linear patterns are on substantially the same plane of the superlattice cross section, so that the linear patterns enable a position of the superlattice pattern to be identified.

  • Patent number: 7872246
    Abstract: When the second harmonic of a YAG laser is irradiated onto semiconductor films, concentric-circle patterns are observed on some of the semiconductor films. This phenomenon is due to the non-uniformity of the properties of the semiconductor films. If such semiconductor films are used to fabricate TFTs, the electrical characteristics of the TFTs will be adversely influenced. A concentric-circle pattern is formed by the interference between a reflected beam 1 reflected at a surface of a semiconductor film and a reflected beam 2 reflected at the back surface of a substrate. If the reflected beam 1 and the reflected beam 2 do not overlap each other, such interference does not occur. For this reason, a laser beam is obliquely irradiated onto the semiconductor film to solve the interference. The properties of a crystalline silicon film formed by this method are uniform, and TFTs which are fabricated by using such crystalline silicon film have good electrical characteristics.

  • Patent number: 7872241
    Abstract: An electron beam production and control assembly includes a vacuum chamber, a beam source, and a target. The target has an active section and an inactive section. The active section is adapted to generate x-rays when the beam impinges on the x-ray producing section. The electron beam production and control assembly also includes a focusing unit positioned along the chamber at a location intermediate the rearward end and the forward end. The focusing unit directs the beam towards the target in a converging manner to impinge on the target. The focusing unit sweeps the beam along a scanning path over the active section of the target. The focusing unit moves the beam to a retrace path on the inactive section of the target between sweeps of the scanning path to maintain ion accumulation in the beam between sweeps over the active section.
