    摘要： The present invention provides a reticle inspection technology that enables a relative position between patterns to be evaluated for a pattern that may become a defect at the time of exposure to a sample, such as a wafer, in the double patterning technology on the same layer. An apparatus for inspecting a reticle for inspecting two reticles that are used in order to form patterns in the same layer on a substrate using the double patterning technology has: a coordinate information input unit for inputting coordinate information of a pattern of a measuring object; an image input unit for acquiring images of patterns of the two reticles based on the obtained coordinate information; an image overlay unit for overlaying the images of the two reticles at the same coordinates; a relative position calculation unit for finding the relative position between the patterns on the two reticles; an evaluation unit for assigning an index of the overlaying accuracy based on the relative position and evaluates whether the two reticles need repair; and an evaluation result output unit for outputting an evaluation result.

    摘要： A system and method are provided for compensating for proximity effects between selected adjacent portions of pattern elements on an integrated circuit wafer where it is determined by simulation that undesirable resist patterns will result. The subject lithography system includes projecting an electron beam onto the wafer through an aperture plate of pattern elements to obtain the desired beam pattern. An aperture mask includes a plurality of first portions corresponding to first wafer circuit element portions spaced for avoiding proximity effects on the wafer and a plurality of second portions corresponding to second element portions spaced for obtaining proximity effects between elements on the wafer. The plurality of second portions are sized to have an increased adjacent spacing relative to a resultant adjacent spacing of the corresponding second element portions whereby the resultant adjacent spacing of the second element portions on the wafer is selectively reduced by the proximity effects. Alternatively, or in addition, a wire mesh is provided at the second portions of the aperture plate to reduce the beam intensity for corresponding reduction of the proximity effects.

    摘要： An electron beam drawing apparatus having a grounded conductor for a screening operation in the neighborhood of a detection surface of a detector to detect a reflected electrons obtained by irradiating an electron onto a specimen and a secondary electron generated through the electron irradiation. The conductor has openings to pass therethrough the reflected electron and the secondary electron. As a result, the electric charge accumulated on an organic substance fixed onto the front surface of the detector through the electron irradiation is prevented from exerting an influence on the drawing electron beam.

    摘要： This invention relates to a method of producing a semiconductor device which is suitable for forming a bipolar transistor having less fluctuation of characteristics at a high production yield.In accordance with the present invention, a graft base (or an extrinsic base) 20 is formed by doping an impurity from a polycrystalline silicon film 13, while an emitter is formed by lithographic technique.Since the emitter is formed by lithographic technique, the position at which the emitter is to be formed unavoidably changes at the time of mask alignment, but its influence upon transistor characteristics is negligible. Therefore, bipolar transistors having far more uniform characteristics can be formed far more easily than with the method which forms the emitter by self-alignment.

    摘要： Desired portions of the positive-type photoresist film are irradiated with an electron beam, and regions including at least the regions irradiated with the electron beam are further irradiated with ultraviolet light, followed by developing.The photosensitive radicals are destroyed in the regions which are irradiated with the electron beam. Therefore, the solubility of the photoresist film is not increased even when it is irradiated with ultraviolet light, and resist patterns are formed by developing.
