Abstract:
1. A method for alignment processing comprising: making a substrate, coated with an aligned film, closely face a photo mask, which has a first mask pattern group having a plurality of first elongated openings formed at a fixed array pitch and a second mask pattern group provided parallel to the first mask pattern group and having a plurality of second elongated openings formed at the same pitch as the array pitch of the first openings, and moving the substrate in a direction crossing the first and second mask pattern groups; directly applying one of two polarizations to the first mask pattern group and directly applying the other to the second mask pattern group, wherein the two polarizations have been separated by a reflecting surface of a beam splitter disposed so that the reflecting surface is provided in a plane crossing vertical to the photo mask at an intermediate position between the first and second mask pattern groups of the photo mask, and the two polarizations are different from each other in at least one of polarization direction and incidence angle; and alternately forming, on the aligned film, first and second slit alignment regions in different aligned states.
