Abstract
Upon a substrate containing different zones which are to be connected with one another, there are successively deposited a layer of thickness e.sub.1, of a first metal (tantalum) oxidizable by heat treatment, and a layer of thickness e.sub.2 of a second metal (aluminium) non-oxidizable by said treatment, deposited upon the surface of the first layer in accordance with the desired connection profile. The thickness of the aluminium layer is controlled so that it is equal to the increase in thickness of the tantalum layer as a consequence of the transformation of the tantalum into tantalum oxide.
