Zusammenfassung:PROBLEM TO BE SOLVED: To provide a mechanism of decreasing electrostatic charges on a side face of a substrate. SOLUTION: A substrate cover 10 is placed on a substrate 101 where an image is drawn by using an electron beam, and the cover comprises: a frame 12 having an outer dimension larger than the circumference end of the substrate 101 and having an opening in the center part in a dimension smaller than the circumference end of the substrate; and a grounding pin 16 which is provided on the lower face side of the frame 12 and connected to electrically conduct the substrate 101. By this method, deviation of a beam trajectory due to electrostatic charges on a side face of the substrate 101 can be prevented. COPYRIGHT: (C)2008,JPO&INPIT
