DOUBLE LAYER TRANSFER METHOD

摘要

Method of transferring a layer (1) comprising: a) providing a layer (1) integral with an initial substrate with a binding energy EO; b) bonding a front face (8) of the layer (1) to an intermediate substrate (5) according to an intermediate binding energy Ei; c) detaching the initial substrate from the layer (1) e) bonding a rear face to a final substrate (11) according to a final binding energy Ef; and f) detaching the intermediate substrate (5) from the layer (1) to transfer the layer (1) to the final substrate (11); step b) comprising a step of forming Si-O-Si siloxane bonds, step c) being carried out in a first anhydrous atmosphere and step f) being carried out in a second humid atmosphere in such a way that intermediate binding energy Ei takes a first value Ei1 in step c) and a second value Ei2 in step f), where Ei1 > E0 and Ei2 < Ef.
