A method for forming interconnection levels of an integrated circuit, including the steps of: (a) forming an interconnection level including conductive tracks and vias separated by a porous dielectric material; (b) forming, on the interconnection level, a layer of a non-porous insulating material, said layer comprising openings above portions of porous dielectric material; (c) repeating steps (a) and (b) to obtain the adequate number of interconnection levels; and (d) annealing the structure. |
