A method for crystallizing a thin film A gate insulating film formed on a substrate so as to cover a gate electrode. A light absorption layer is formed thereon through a buffer layer. Energy lines Lh are applied to the light absorption layer from a continuous-wave laser such as a semiconductor laser. This anneals only a surface side of the light absorption layer Lh and produces a crystalline silicon film obtained by crystallizing the amorphous silicon film using heat generated by thermal conversion of the energy lines Lh at the light absorption layer and heat of the annealing reaction.

摘要:
A recording medium comprises a substrate and a recording layer overlaid on the substrate. The recording layer comprises a material, which has properties such that, when recording light having a predetermined wavelength λ1 is irradiated to the material, the material is capable of being caused to change into a fluorescent material and such that, when excitation light having a wavelength λ2 is then irradiated to the thus formed fluorescent material, the fluorescent material is capable of being caused to produce fluorescence. The wavelength λ1 of the recording light and the wavelength λ2 of the excitation light may be identical or different. The substrate may be constituted of a material having properties such that, when the excitation light is irradiated to the material, the material does not produce fluorescence having a wavelength identical with the wavelength of the fluorescence produced by the fluorescent material.
