    摘要: Methods and apparatus for alignment of masks and wafers in charged-particle-beam (CPB) pattern-transfer use optical position sensors to determine the positions of a mask or a mask stage with respect to an axis of a CPB optical system. The optical position sensor uses optical reference marks provided on the mask or mask stage. Determination of the position of the mask of the mask stage permits a coarse alignment of the mask or the mask stage. CPB reference marks are provided on masks, mask stages, wafers, and wafer stages, permitting alignment of the mask stage or the mask with respect to the wafer stage or wafer, respectively, using the charged particle beam. The charged particle beam is scanned with respect to the wafer or wafer-stage CPB reference marks to determine a deflection corresponding to an alignment of the CPB reference marks of the mask and wafer (or mask stage and wafer stage). Use of the charged particle beam for such alignment permits a fine alignment.

    摘要: The present invention is a method of inspecting a surface-emitting semiconductor laser in which a resonator is formed in a vertical direction on a semiconductor substrate. The surface-emitting semiconductor laser to be inspected includes a pillar portion in at least part of the resonator, and this pillar portion includes an oxidized current blocking layer. The oxidized current blocking layer includes an oxide aperture, and an oxidized portion formed around the oxide aperture. The surface-emitting semiconductor laser is irradiated with laser light in a direction perpendicular to a surface of the semiconductor substrate from the side on which the pillar portion is disposed, and the shape of the oxide aperture is measured based on the amount of reflected light at the oxidized current blocking layer.

    摘要: A sheet detecting device has a light emitting and receiving unit having a light emitting element for emitting detection light and a light receiving element for receiving the detection light, and a reflecting member for reflecting the detection light emitted from the light emitting element and making the reflected light incident to the light receiving element, and is constructed in a configuration wherein the light emitting and receiving unit and the reflecting member are placed with a sheet transport path between. The sheet detecting device is configured to detect a sheet on the basis of interruption of the detection light by the sheet transported through the sheet transport path. The sheet detecting device has an emission slit which restricts the detection light emitted from the light emitting element and which is arranged so as to be longitudinal along a sheet transport direction, and a reception slit which restricts the detection light incident to the light receiving element and which is arranged so as to be longitudinal along a direction intersecting with the sheet transport direction.
