    摘要: Apparatus for realtime fast reconstruction and display of dose distribution which calculates the dose of absorbed radiation in an irradiated area defined by coordinates and displays the results of the calculation. The apparatus comprises an input unit capable of setting parameters in the form of time-continuous quantities; a dedicated digital computer serving to control the input by the input unit; and a dedicated fast reconstructer for calculating the absorbed dose for each coordinate in the exposed area at a high speed by decomposing calculation formulae necessary for obtaining isodose curves on the basis of the parameter set in the input unit and effecting parallel calculation of the decomposed formulae, thereby obtaining the isodose curves; and video display for storing and displaying the isodose curves classified in terms of different isodose levels. The calculation is normally cyclically repeated to provide a motion picture of the dose distribution when the magnitude of the parameters is varied.

    摘要: An exposure apparatus of this invention is used in an exposure process of semiconductor and LCD devices. The exposure apparatus includes a stage on which a semiconductor wafer is placed, a rotating mechanism for rotating the stage, a radiation unit arranged to oppose a support surface of the stage, a slider mechanism for reciprocating the radiation unit along a straight line passing through the center of the support surface of the stage, an exposure range input unit for inputting a desired exposure range of the wafer, an exposure range memory unit for storing the input exposure range, a CCD image sensor for detecting a reference position of the wafer, a relative position detector for detecting a relative position between the detected reference position and the radiation unit, a controller for controlling the sliding mechanism in correspondence with the relative position and the exposure range, and a light amount control mechanism for controlling an amount of light radiated from the irradiation mechanism to the wafer in correspondence with the relative position and the exposure range.
