Abstract

The invention relates to a method for production of a detachable substrate, comprising a method step for the production of an interface by means of fixing, using molecular adhesion, one face of a layer on one face of a substrate, in which, before fixing, a treatment stage for at least one of said faces is provided, rendering the mechanical hold at the interface at such a controlled level to be compatible with a subsequent detachment.
