摘要： A pattern inspection apparatus determines a difference of the measured dislocation of respective alignment marks of an opaque pattern and a phase shifting pattern (measurement difference), in addition to a difference between the both alignment mark positions in design (design difference). A difference between the measurement difference and the design difference is set as a difference in alignment mark position between the opaque pattern and the phase shifting pattern in a reference pattern which is later used in inspection. In this manner, by correcting one pattern data with respect to the other pattern data in the reference pattern, the displacement generated in the both patterns can be reflected, and the reference pattern data regarding an image of a sample which is actually observed can be created.

摘要： A vane pump has an upper casing, a lower casing, a rotor and a motor. First to fourth points are defined on an outer peripheral end of a lower flat surface of the lower casing. The first point is farthest from an intersection between an axis of a shaft of the motor and the lower flat surface. A suction passage passing through the third point and a discharge passage passing through the second point are formed between the upper casing and the lower casing. The fourth point is defined in a range from the third point to the first point. The lower flat surface is provided to incline with respect to the axis of the shaft of the motor such that the fourth point is farthest from a motor case of the motor among points on the outer peripheral end.

摘要： In an automatic focus adjusting mechanism, a test sample having a patterned surface is mounted on a mount table, and an light beam passing through a slit formed in a field stop is applied to the patterned surface of the test sample. The light beam reflected from the test sample is split into two segment light beams. Focus adjusting aperture stops having respective apertures formed rhomboid are provided across the optical paths of the segment light beams. The amounts of the segment light beams passing through the rhomboid apertures are detected by light receiving units. Based on the difference between the detected light amounts, the position of the mount table is controlled by the focus adjusting unit.

摘要： The thickness of an antiferromagnetic layer (IrMn) and the thickness of a nonmagnetic interlayer (Cu) are adjusted so as to be within the area surrounded by boundaries a to f on the graph of FIG. 6 in which the horizontal axis represents the IrMn film thickness and the vertical axis represents the Cu film thickness. Consequently, the interlayer coupling magnetic field Hin can be made to be 10 Oe or more, and the variation in the interlayer coupling magnetic field Hin can be made to be 2 Oe or less. In addition, in the area surrounded by boundaries a to f, at any IrMn film thickness, the Cu film thickness range in which the variation can be made to be 2 Oe or less can be set over a wide range, as compared with a known structure.

摘要： An image correction device for use in a pattern inspection apparatus is disclosed, which has automatic adaptability to variations in density of a pattern image of a workpiece being tested. The device is operable to identify a two-dimensional (2D) linear predictive model from the pattern image of interest and determine the amount of eccentricity of a centroid position of this model. This amount is then used to switch between a corrected pattern image due to the 2D linear prediction modeling and a corrected image that is interpolated by bicubic interpolation techniques. A pattern inspection method using the image correction technique is also disclosed.
