Title: Exposing method and equipment thereof
Inventor: SAITO KENJI
IPC: G03F1/68
Filed: 2001-04-24
Abstract: PROBLEM TO BE SOLVED: To provide an exposing method and equipment which can expose a mask pattern having fine (e.g. at most 0.15 μm) line width, with high resolution without changing a mask, in which mask pattern various kinds of patterns, L and S patterns, isolated and complicated patterns exist mixedly.

Out of the desired pattern, a part which is to be resolved by the effect of the dummy pattern is made wider than the line width of the dummy pattern, thus forming the phase shift mask. By using an illumination light which has a peak of intensity distribution in the vicinity of an optical axis, the phase shift mask is illuminated. A light which passed the phase shift mask is projected on a surface to be exposed via a projection optical system. As a result, the desired pattern is transferred on the surface to be exposed.
