Abstract (en)

[origin: WO2007014775A1] A method for successively functionalising a substrate whose surface is provided with at least two areas (1, 2) made of different materials with the aid of at least one chemical substrate is characterised in that the functionalisation is carried out without masking and consists (a) in functionalising a first area (1) without masking the second area (2) or possible successive areas by transforming the substrate with the aid of a chemical substance X<SUP>1</SUP>, wherein the first area material reactivity is greater with respect to the reactivity of the substance X<SUP>1</SUP> than the reactivity of the other possible successive areas with respect thereto, and (b1) in treating the second area (2) or the other possible successive areas with a chemical substance Y<SUP>1</SUP> for removing reaction products deposited on said areas during the functionalisation from the areas of the substance X<SUP>1</SUP> and/or the possible successive areas without damaging the functionalised surface of the first area.
