Abstract
A method of transferring a layer including: a) providing a layer joined to an initial substrate with a binding energy E0; b) bonding a front face of the layer on an intermediate substrate according to an intermediate bonding energy Ei; c) detaching the initial substrate from the layer; e) bonding a rear face onto a final substrate according to a final bonding energy Ef; and f) debonding the intermediate substrate from the layer to transfer the layer onto the final substrate; step b) comprising a step of forming siloxane bonds Si—O—Si, step c) being carried out in a first anhydrous atmosphere and step f) being carried out in a second wet atmosphere such that the intermediate bonding energy Ei takes a first value Ei1 in step c) and a second value Ei2 in step f), with Ei1>E0 and Ei2<Ef.
