  • Patent number: 9798126
    Abstract: A modular illumination system is capable of producing a light beam having a wide field of view—e.g., in excess of ninety degrees—while maintaining a high collection efficiency as well as a high degree of beam homogeneity. The illumination system comprises an elementary unit having a linear array of light sources. Light from the light sources is collimated using a corresponding array of catadioptric lenses, and the collimated light is homogenized in the tangential plane using two cylindrical lens arrays set in tandem to one another. The homogenized light is then collimated in the sagittal plane using a cylindrical lens that is set perpendicular to the lenses of the two cylindrical lens arrays to yield a wide linear beam. To produce an area beam, the linear array of light sources can be replaced with a two-dimensional array, and the cylindrical lenses can be replaced with spherical lenses.

  • Patent number: 9715176
    Abstract: A first drive system of a first stage and a second drive system of a second stage are controlled based on measurement information of a first encoder system and a second encoder system, respectively, and so that a mask and a substrate are moved relative to illumination light in scanning exposure of the substrate. To move the second stage in another second area, one head of the second encoder system, different from two heads, of three heads used in one second area is switched to another head so that drive control of the second stage by three heads, including the another head and the two heads, that are used in the another second area is performed, instead of drive control of the second stage by the three heads used in the one second area. The switching is performed while the second stage is in a first area.

  • Patent number: 9716008
    Abstract: An apparatus for doping impurities includes: a bath reserving liquid containing impurity elements; a liquid transport device transporting the liquid on a surface of a semiconductor substrate; a laser optical system which scans and irradiates light pulses of laser onto the surface of the semiconductor substrate; an X-Y manipulator moving the semiconductor substrate; and an arithmetic and control unit which controls the liquid transport device and X-Y manipulator. Flow rate of the liquid and scanning velocity of the light pulses are determined, by a characteristic dimension of the irradiation area along the flow direction of the liquid, an overlapping ratio of the irradiation area, and the radius of a bubble generated in the liquid. The impurity elements are doped into a part of the inside of the semiconductor substrate at the determined flow rate and scanning velocity.
