Abstract
PURPOSE: To work a plane shape precisely, and to improve etching reproducibility in the direction of depth, by irradiating the surface of a solid with ions to form damaged portions in which the geometrical shape of a mask is reflected correctly, then by conducting etching.
CONSTITUTION: In forming a diffraction grating on the surface of a GaAs crystal, a resist 12' is applied uniformly on the GaAs substrate 11, and the resist 12' is exposed to a laser using the interference effect of the laser and is developed to form a mask 12 having wave-like sectional shape of submicron period which depends upon the wave length of the laser. A beam 13 such as that of Ar+ etc. is irradiated through the mask 12 on the substrate 11 to form damaged parts 14 in the substrate 11. Then the maks 12 is removed, and etching is conducted, thereby forming GaAs crystal having wave-like surface shape of submicron period. Hence this method permits to form a diffraction grating having concave and convex structure of regular period.
