    Abstract: Method for producing a composite structure (200), comprising the direct bonding of at least one first wafer (220) with a second wafer (230), and comprising a step of initiating the propagation of a bonding wave, where the bonding interface between the first and second wafers (220, 230) after the propagation of said bonding wave has a bonding energy of less than or equal to 0.7 J/m2. The step of initiating the propagation of the bonding wave is performed under one or more of the following conditions: - placement of the wafers in an environment at a pressure of less than 20 mbar, - application to one of the two wafers of a mechanical pressure of between 0.1 MPa and 33.3 MPa. The method further comprises, after the step of initiating the propagation of a bonding wave, a step of determining the level of stress induced during bonding of the two wafers, said level of stress being determined on the basis of a stress parameter Ct calculated using the formula Ct = Rc/Ep, where: Rc corresponds to the radius of curvature (in km) of the two- wafer assembly and Ep corresponds to the thickness (in μm) of the two-wafer assembly. The method further comprises a step of validating the bonding when the level of stress Ct determined is greater than or equal to 0.07.
