An exposure apparatus for transferring patterns on a phase shift mask into a wafer according to the present invention comprises a light source, a polarized light illuminator that selectively passes through a TM mode polarized light of light from the light source to cause it to be incident onto the phase shift mask, a polarization mode translator that translates the TM mode polarized light passing through the phase shift mask into TE mode polarized light, and a lens system irradiating the TE mode polarized light from the polarization mode translator on the wafer.
