The photosensitive material also comprises at least one first dye which has an absorption peak wavelength in the wavelength region longer than 400 nm but at least 20 nm shorter than the shortest of the wavelengths which form the peak values of the spectral sensitivities of the photosensitive layers. This first dye can be included in a photosensitive layer and/or a non-photosensitive hydrophilic colloid layer. The photosensitive material can also contain at least one second dye which has an absorption peak wavelength at a wavelength region of 670 nm to 1000 nm.

A gate insulating film (13) is formed on a substrate (1) so as to cover a gate electrode (11), and an amorphous silicon film (semiconductor thin film) (15) is further formed. A light absorption layer (19) is formed thereon through a buffer layer (17). Energy lines Lh are applied to the light absorption layer (19) from a continuous-wave laser such as a semiconductor laser. This oxidizes only a surface side of the light absorption layer Lh and produces a beautiful crystalline silicon film (15a) obtained by crystallizing the amorphous silicon film (15) using heat generated by thermal conversion of the energy lines Lh at the light absorption layer (19) and heat of the oxidation reaction. This provides a method for crystallizing a thin film with good controllability at low costs achieved with simpler process.
