Zusammenfassung:PROBLEM TO BE SOLVED: To provide a lithographic system that maintains appropriate throughput performance, and at the same time, can improve connection accuracy in a pattern. SOLUTION: As the multilens of an apparatus for drawing a pattern to a wafer by a plurality of charged beams, a multilens 1 is used. In the multilens 1, an electronic lens (lens openings 9a to 9i) using the intersection (a lattice point) between lines X1, X2, X3 in a horizontal direction and lines Y1, Y2, Y3 in the vertical direction for composing a virtual lattice as an axis, and electronic lens (lens openings 9j to 9m) using the center of each square for constituting the virtual lattice as an axis.
