Disclosed are an asymmetric pattern forming technique using a phase shift mask, and also a technique for manufacturing a diffraction grating and semiconductor device, whereby improved accuracy of the product and a shortening of manufacturing time can be achieved. A method of manufacturing a diffraction grating using a phase shift mask (30) (a light-blocking part and a light-transmissive part (a first light-transmissive part when there is no phase shift, a second light-transmissive part when there a phase shift) are disposed periodically), wherein a beam of light emitted from an illumination light source (10) is passed through a phase shift mask (30). The zeroth order beam and the +1 order beam generated by passing through this phase shift mask (30) are caused to interfere at the surface of an Si wafer (50). A photoresist (60) at the surface of this Si wafer (50) is thereby exposed, and a diffraction grating is thus formed having a cross-sectional shape of blazed form on the Si wafer (50).
