Patent ID: 8067060

Claim:
A method for forming a continuous polymer layer on a non-flat surface of a support, said non-flat surface comprising a flat main part and at least one recessed zone with respect to the flat main part, the method comprising at least the following successive steps: deposition of a predetermined quantity of a liquid mixture comprising at least a polymer or at least a precursor of said polymer on the flat main part of the non-flat surface, partially filling the at least one recessed zone with the liquid mixture by passing a cylinder or a roller on the flat main part of the non-flat surface in order to move the liquid mixture present on the flat main part to the at least one recessed zone and to prevent the flat main part from being covered by the liquid mixture, wherein the cylinder or roller remains in contact with the flat main part during passage of the cylinder or roller, deposition of an additional quantity of the liquid mixture on the flat main part of the non-flat surface, and rotation of the support along an axis perpendicular to the plane of the non-flat surface to form the continuous polymer layer.
