Abstract
A method for crystallising an amorphous layer included in a stack, extending directly in contact with a crystalline layer of the stack by forming an interface with the crystalline layer, and having a first face opposite the interface, and having a melting threshold Ecorresponding to the energy density to be provided to the amorphous layer to achieve its melting, for a thickness Ep of the amorphous layer defined between the first face and the interface, the method including a crystallisation annealing of the amorphous layer by subjecting it, by zones, to laser pulses, and in each zone, the laser pulses are emitted by series, each laser pulse having an energy density EDdifferent from one series to another so as to maintain the energy density of the pulses of each series below the melting threshold.
