Abstract:
A process for processing or forming a material by electromagnetic radiation and in a controlled atmosphere or in a vacuum inside a reaction chamber, the assembly being subjected to a first infrared radiation causing rapid heating to a preset temperature so as to modify the physico-chemical properties of the material arranged on a substrate or to perform deposition of the material on said substrate, whereina second excimer type ultraviolet radiation, having a spectral resolution lower than 40 nm regardless of the wavelength of the ultraviolet radiation is used inside said reaction chamber so as to generate a photon flux suitable either for modification of the physico-chemical properties of the material or for formation of said deposit,the exposure time of the second ultraviolet radiation is shorter than that of the first infrared radiation,the processing temperature is comprised between 70.degree. C. and 800.degree. C. according to the nature of the material.
