Abstract:
A method for forming a thin film of a complex compound on an upper surface of a substrate for a semiconductor device, comprising:coating a sol-gel solution on the substrate to form a thin film on the substrate;exposing the surface of the thin film to radiation in order to promote hydrolysis polycondensation in the thin film; andbaking the thin film exposed to radiation in order to form the thin film of the complex compound on the upper surface of the substrate;wherein the sol-gel solution is coated on the substrate in a thickness sufficient to form, in a single process including the coating, exposing and baking steps, the thin film of the complex compound in a thickness greater than a maximum thickness in which a thin film of complex compound is formed without cracking by a process including coating and baking steps without an intermediate irradiation step.
