METHOD OF FORMING A PATTERN ON THE SURFACE OF A SUBSTRATE

摘要

The invention relates to a method of forming a pattern on the surface made of a hydrophobic macromolecular material of a substrate. The method of the invention also comprises a step a) of immersing at least said surface of the substrate in a solution that comprises at least 50% by volume of water and, optionally, one or more polar solvents having a dielectric constant greater than 30 and contains less than 0.0001 mol/L of dissolved gases and an ion source. The invention is particularly applicable in the electronics field.
