METHOD OF LOCALIZED ELECTROGRAFTING ONTO PHOTOSENSITIVE SEMICONDUCTOR SUBSTRATES

摘要

The present invention relates to a method of preparing an organic film on a selected area of the surface of a photosensitive semiconductor substrate, characterized in that it comprises the following steps: (i) a liquid solution comprising at least one organic adhesion primer is brought into contact with at least said selected area; (ii) the surface of said substrate is biased with an electrical potential more cathodic than the reduction potential of the adhesion primer used in step (i); and (iii) said selected area is exposed to light radiation of energy at least equal to that of the bandgap of said semiconductor.
