Off-axis illumination (OAI) technology is widely used to enhance resolution for deep ultraviolet lithography. The realizing methods of OAI include geometrical optics method and physical optics method. However  the former has the disadvantage of weak intensity distribution controlling ability  and the latter introduces simulation errors evidently when dealing with near field diffraction propagation. A diffractive optical element (DOE) designing method using plane wave angular spectrum theory is presented in this paper. Several kinds of OAI modes at near field away from DOE can be realized  and simulation errors and the size of illuminator are also reduced. According to studying the relationships of the sampling point distance of DOE  light beam propagation distance  and the structure of the beam shaping unit  a method of determining the designing parameters is discussed. Using this method  several illumination modes are realized  and simulation results show that all diffraction efficiencies reach up to 84%. The method of DOE manufacturing is analyzed at last  and it is proven to be feasible. 2010 SPIE.
