The system for drawing a pattern on a resist layer covering a semiconductor wafer, comprising an electron gun housing unit provided with a plurality of small-sized electron guns (wherein the housing unit has a hollow column section for releasing an electron beam, and a micro deflection unit is disposed inside for adjusting the inclination of the electron beam), a movable stage capable of moving in the X-Y directions, a wafer stage disposed on the movable stage to support a semiconductor wafer, a mask wafer having struts on its rear side for supporting membranes on which a pattern to be transferred is formed, a mask stage for holding the mask wafer, a matching detection unit for detecting a misalignment between the mask wafer and the semiconductor wafer, and an inclination means connected to the micro deflection unit and the matching detection unit for inclining the electron beam. |
