| titleOfInvention | Diffractive optical element, method of manufacturing the same, optical pickup device and optical disk drive device |
| abstract | (57) [Problem] To effectively eliminate the warpage of a substrate when manufacturing a diffractive optical element. A step of bonding and fixing an organic material film on a transparent substrate, a step of forming a plurality of diffraction gratings RL having rectangular irregularities on the organic material film in a grid arrangement are formed. A method of manufacturing a diffractive optical element having a separation step of individually separating a plurality of diffraction gratings. A groove for alleviating the warp is formed in the organic material film 3 from the side of the organic material film 3 by at least one streak in the vertical and horizontal directions of the lattice-like arrangement of the diffraction grating in the substrate warped by the heat shrinkage of the substrate. And forming the transparent substrate 1A to a depth not less than the thickness of the transparent substrate 1A. |
