    摘要： An automated optical inspection system, comprising at least one camera having a field of view; and at least one image scanning module comprising a plurality of objective modules arranged to have fields of view covering a portion of an article during inspection, and an image selection mirror mechanism, such as a pentaprism movable to sequentially select and transfer images of the fields of view from the objective modules to the at least one camera, and a beam splitter operative to simultaneously direct illumination from at least one illumination source to a portion of the article and to direct an image of the portion of the article to at least one camera, wherein the beam splitter is operative to pivot about at least one axis, thereby to create motion of the image of the article within the field of view of the camera. The objective modules may be arranged in a pair of back-to-back arcs each served by and partially encircling its own optical head. The image selection mirror mechanism may be rotated by a rotating shaft having a driving end, the mechanism being disposed between the shaft's driving end, and the article.

    摘要： A laser scanning device is disclosed which includes a spinner, one light spot misalignment detector and a beam misalignment corrector. The spinner scans a light beam across a scanning line. The detector is located generally at a beginning of the scanned line and measures an initial misalignment of the light spot in a cross-scanning direction. The corrector dynamically corrects, during scanning along said scanning line, the scanning misalignment of the light beam in accordance with at least the initial misalignment. The corrector includes a pre-positioner which determines an offset for the initial misalignment, a pyramidal error estimator which estimates a first portion of the misalignment due to pyramidal error and a wobble estimator which estimate a second portion of the misalignment caused by wobble. The estimations are summed together and used for correcting the misalignment.

    摘要： A reticle inspection system and method for complete and fast inspection of phase shift mask reticles, both for incoming inspection and for periodic and pre-exposure inspection tool, is employable by facilities such as mask shops as an inspection tool compatible to the mask shop's customers. The inventive system and method detect phase errors in an aerial image by acquiring the image of the phase shift mask under the same optical conditions as the exposure conditions (i.e. wavelength, numerical aperture, sigma, and illumination aperture type). Images are acquired at a positive out-of-focus and a negative out-of-focus, and are compared in order to enhance possible phase error. The term “phase error” refers to the acceptable range of the phase deviation from the programmed 180° on the phase shift mask, by using the exposure system to achieve the image on the photoresist, satisfying the requirements of the wafer specification.
