20090262621 | METHOD AND APPARATUS FOR INSPECTING A PATTERN SHAPE - An apparatus for inspecting a pattern shape of a magnetic record medium or its stamper includes: a moving mechanism, on which an object to be inspected where a pattern is formed is placed and which moves the object to be inspected in a radial direction while rotating the object; an irradiating optical system that applies illuminating light of a wide band including far ultraviolet light to the object to be inspected moved in the radial direction while rotating the object by the moving mechanism in a polarized state suitable for the object to be inspected from an oblique direction; a detecting optical system that detects zero-order reflected light generated from the object to be inspected irradiated by the irradiating optical system; and a shape inspection unit that inspects a pattern shape formed on the object to be inspected based on a spectral reflectance waveform obtained by dispersing the detected zero-order reflected light, thereby inspecting the pattern shape at a high speed and with high sensitivity. | 2009-10-22 |
