A character projection charged particle beam writer system is disclosed comprising a variable magnification reduction lens which will allow different shot magnifications on a shot by shot basis. A method for fracturing or mask data preparation or optical proximity correction is also disclosed comprising assigning a magnification to each calculated charged particle beam writer shot. A method for forming a pattern on a surface is also disclosed comprising using a charged particle beam writer system and varying the magnification from shot to shot. A method for manufacturing an integrated circuit using optical lithography is also disclosed, comprising using a charged particle beam writer system to form a pattern on a reticle, and varying the magnification of the charged particle beam writer system from shot to shot. |
