A three-dimensional integrated structure is fabricated by assembling at least two parts together, wherein each part contains at least one metallic line covered with a covering region and having a free side. A cavity is formed in the covering region of each part, that cavity opening onto the metallic line. The two parts are joined together with the free sides facing each other and the cavities in each covering region aligned with each other. The metallic lines are then electrically joined to each other through an electromigration of the metal within at least one of the metallic lines, the electromigrated material filling the aligned cavities.

Process for assembling two parts of a circuit

The integrated circuit comprises a support substrate having opposite first and second main surfaces. A cavity passes through the support substrate and connects the first and second main surfaces. The integrated circuit comprises a device with a mobile element, the mobile element and a pair of associated electrodes of which are included in a cavity. An anchoring node of the mobile element is located at the level of the first main surface. The integrated circuit comprises a first elementary chip arranged at the level of the first main surface and electrically connected to the device with a mobile element.

An interface plate capable of being mounted between first and second surface-mounted electronic chips. The plate includes a plurality of first, second, and third through openings, the first openings being filled with a conductive material and being arranged to be in front of pads of the first and second chips during the assembly, the second openings being filled with a second material, the third openings being filled with a third material, the second and third materials forming two complementary components of a thermoelectric couple.
