    摘要: The present invention relates to an exposure method of a multi-beam type in which a stage mounting a sample to be exposed is continuously moved in a first direction, and charged-particle beams are controlled so as to form a desired beam shape as a whole, and in which a pattern is formed on the sample by deflecting the charged-particle beams by a main deflector and a sub deflector. Patterns to be drawn are divided into pattern data on a cell stripe basis which corresponds to an area which can be exposed when the sub deflector scans the charged-particle beams one time. The pattern data on the cell stripe basis is stored into a memory. Then, position data indicative of cell stripes is stored, in an exposure sequence, together with address information concerning the memory in which the pattern data is stored. The deflection amount data relating to the main deflector and the sub deflector is calculated from the position data. Patterns are drawn on the wafer by using the pattern data and the deflection amount data.

    摘要: A charged-particle beam exposure method is used for a charged-particle beam exposure apparatus equipped with a blanking aperture array plate in which columns are arranged side by side in a first direction, and each of the columns includes a plurality of blanking apertures arranged in a second direction substantially perpendicular to the first direction, a charged-particle beam being moved on a wafer in the first direction. The method includes the steps of (a) determining one of first and second axes of a pattern to be exposed to be a priority axis; (b) projecting an image of the blanking aperture array plate onto the wafer so that the priority axis is perpendicular to the second direction; and (c) deflecting the charged-particle beam so that the wafer is scanned in the direction of the priority axis.

    摘要: A device exposing an object to an electron beam employs a mask formed of a plate of material which blocks the electron beam and which has plural pattern exposure blocks defined therein, each having one or more aperture defining regions therein and, when selected, determining the shaping of the electron beam passing therethrough so as to expose a respective pattern on an object. Each aperture-defining region has a respective single aperture or respective plural, spaced apertures formed therein and having a total area size selected to be smaller than the area size of the aperture defining region, in accordance with controlling the current level of an electron beam passing therethrough, while reducing Coulomb interaction of the electron beam passing through the aperture or apertures of each aperture defining portion of the pattern exposure block.
