Abstract (en)
[origin: WO2006040419A1] The invention relates to a method for producing layers located on a hybrid circuit, wherein said hybrid circuit comprises a substrate (20) and at least one elementary circuit (22) comprising a first face and a second face by which it is hybrided to the substrate face. The inventive method consists in covering said first substrate face and each elementary circuit with a first layer (24), in removing the first layer from the first face of the elementary circuit, in covering the first face and the remaining portion of the first layer by a second layer (28) and in removing said remaining portion and the second layer which covers it. Said invention can be used for producing an antireflective or metal layer on a chip.
