A serigraphy method for producing a soulder bump on the front surface of a substrate includes: forming a film on the front surface, forming an opening in the film, filling the opening with a souldering material, and removing the film. Forming a film on the front surface is preceded by the formation of an intermediate layer between the film and the front surface, the intermediate layer being adapted to exhibit a force of adherence at one and/or the other interface formed with the first front surface and the film lower than the force of adherence that can be formed between the film and the first front surface.
