To provide an exposure method and an exposure apparatus, using a complementary divided mask, designed to enable alignment of a complementary divided mask at a high precision over the entire region of a semiconductor wafer. Further, to provide a semiconductor device fabricated by the exposure method and a method of producing a semiconductor device using the exposure method. In a first region at a middle portion of a semiconductor wafer, the complementary divided mask is aligned by die-by-die alignment method based on detection results of positions of alignment marks provided at the respective chips and the regions are exposed, while in a second region, outside of the first region, where alignment on the complementary divided mask by die-by-die alignment method cannot be used, coordinates of the respective chip in the second region are decided by global alignment method based on detection results of positions of alignment marks detected in the first step and the complementary divided mask is aligned and the regions are exposed. |
