发明名称 Magnetic deflectors and charged-particle-beam lithography systems incorporating same
摘要 Magnetic deflectors for charged particle beams are provided. The magnetic deflectors comprise at least one pair of coils to provide high deflection sensitivity over large regions of uniform deflection without increasing the size of the magnetic core used by the deflectors. Charged-particle-beam lithography systems using such deflectors are also disclosed.
