摘要:
A charged particle beam mask and apparatus and method of using the same employing a mask that includes a substrate and a plurality of substantially rectangular beam passing sections arranged in parallel and to have a trapezoidal shape. In addition, the masks having a matrix of irradiation areas formed thereon where each irradiation area has a matrix of block patterns, are aligned and selectively irradiated to form a desired pattern on an object.
