  • Patent number: 7927389
    Abstract: In a superabrasive grain setting method, a two-dimensionally developed coordinate preparation step is taken, wherein a non-cylindrical area of a mounting surface where a tangential line to the mounting surface in a plane including the axis of the manufacturing mold crosses with the axis of a manufacturing mold is developed into a circular-arc belt-like surface, and a plurality of mounting points are set on the circular-arc belt-like surface in a grid pattern in dependence on mounting positions for superabrasive grains. Then, a rectification step is taken, wherein the grid pattern of the mounting points is rectified in predetermined angular ranges so that the mounting points do not make consecutive point lines in the circumferential direction of the circular-arc belt-like surface. A mounting step is thereafter taken of mounting the superabrasive grains on the mounting surface of the manufacturing mold based on the grid pattern rectified at the rectification step.

  • Patent number: 6060711
    Abstract: Charged-particle beam pattern transfer apparatus and charged-particle beam optical systems are disclosed. A representative charged-particle beam pattern transfer apparatus comprises a projection lens that images patterns from a mask onto a substrate. To reduce off-axis image aberrations, especially anisotropic coma and astigmatism, deflectors are provided that produce a magnetic field such that the effective optical axis of the lenses is along a straight line that is tilted with respect to the mask and the substrate. Focus correctors are provided that produce a magnetic field that corrects image focus. Mathematical descriptions of these magnetic fields are disclosed. With such magnetic fields, the charged-particle beam that irradiates a central region of a subfield on the mask propagates along a straight-line axis through the projection lens, reducing deflection aberration and improving image quality.

  • Patent number: 5952667
    Abstract: Charged-particle-beam microlithography apparatus are disclosed comprising a lens system, such as a variable axis lens (VAL) or variable axis immersion lens (VAIL), that causes a charged-particle-beam incident to an objective lens off-axis to be incident under the same conditions as if the beam were incident on-axis. The objective lens comprises astigmatism-correction deflectors that generate an astigmatism-correction field serving to correct astigmatism of the beam and generate a deflecting magnetic field that corrects the off-axis state in the astigmatism correction field relative to the charged-particle-beam. Thus, generation of aberrations is kept to a minimum even when the charged-particle-beam is incident off-axis.
