- Abstract
- We proposed the new method for obtaining the effect of an off-axis illumination by using a mask grating formed on the photo mask. The grating structure was designed from the source distribution in the conventional off-axis illumination and the rigorous diffraction theory. Its performance was characterized with simulated Bossung curve.
