Measurement method of electron beam current, electron beam lithography method and system

In an electron-beam lithography system for performing a pattern drawing by causing electron beams to be switched ON/OFF at a high speed in an exposure/non-exposure portion, non-straight line property of beam shot dosage relative to beam ON time worsens dimension accuracy of the drawing pattern forme...
