The disclosure relates to a process for treating a structure, the structure comprising, from its back side to its front side, a carrier substrate, an insulating layer and a useful layer, the useful layer having a free surface, the structure being placed in an atmosphere containing chemical species, the chemical species being capable of reacting chemically with the useful layer. This treatment process is noteworthy in that the useful layer is heated by a pulsed laser beam, the beam sweeping the free surface, the wavelength of the beam differing by, at most, plus or minus 15 nm from a central wavelength, the central wavelength being chosen so that the sensitivity of the reflectivity of the structure relative to the insulating layer is zero. |
