A process for preparing an organic film on a selected zone at the surface of a photosensitive semiconductor substrate, including (i) bringing a liquid solution which includes at least one organic adhesion primer into contact with at least the selected zone; (ii) polarizing the surface of the substrate to an electric potential more cathodic than the reduction potential of the organic adhesion primer; and (iii) exposing the selected zone to light radiation, the energy of which is at least equal to that of the band gap of the photosensitive semiconductor substrate.

Process of localized electrografting onto photosensitive semiconductor substrates

A process for mask-free localized grafting of organic molecules capable of being electrically activated, onto a composite surface comprising conductive and/or semiconductive portions, by placing said organic molecules in contact with said composite surface, in which said grafting is performed electrochemically in a single step on chosen, defined areas of said conductive and/or semiconductive portions, said areas being brought to a potential higher than or equal to a threshold electrical potential determined relative to a reference electrode, said threshold electrical potential being the potential above which grafting of said organic molecules takes place.

Method for mask-free localized organic grafting on conductive or semiconductive portions of composite surfaces

The invention relates to a method of bonding a polymer surface to an electrically conductive or semiconductive surface, which method is characterized in that it comprises: It also relates to applications of this method and to structures obtained by its implementation.
