Abstract:
A method for manufacturing heterostructures for applications in the fields of electronics, optics or opto-electronics. This method includes providing a silicon oxide layer with a thickness of less than or equal to 25 nanometers on one of a donor substrate or a receiver substrate or on both substrates, heat treating the substrate(s) that contains the silicon oxide layer at 900° C. to 1,200° C. under a neutral or reducing atmosphere that contains at least one of argon or hydrogen to form layer trapping through-holes inside the silicon oxide, bonding the substrates together at a bonding interface with the silicon oxide layer(s) positioned between them, reinforcing the bonding by annealing the substrates at 25° C. to 500° C. such that the trapping holes retaining gas species at the bonding interface, and transferring an active layer as a portion of the donor substrate onto the receiver substrate to obtain the heterostructure.
