Abstract
A liquid compound or a compound solution is kept in contact with the surface of a solid material (synthetic resin, glass, metal, or ceramic), radiation selected from ultraviolet, visible, and infrared is irradiated on the interface between the surface of the solid material and the compound to optically excite the surface of the solid material and the compound, thereby effecting substitution with a chemical species in the compound, depositing or performing etching with the chemical species. Preferably, a transparent window is kept in tight contact with the surface of a solid material to be treated, a thin layer of the liquid compound or the compound solution is interposed between the surface of the solid material and the transparent window by using capillarity, and ultraviolet, visible, or infrared is irradiated through the window. With this treatment, the irradiated portion can be given hydrophilicity, adhesion properties, printing properties, corrosion resistance, and conductivity.
