    摘要: The present invention is related to a method for producing an integrated circuit device, comprising a Front-end-of-line (FEOL) portion and a Back-end-of-line (BEOL) portion (102). The metallization layers comprise dielectric layers, preferably low-k dielectric layers, with metal conductors and/or interconnect structures incorporated within said dielectric layers. In a device according to the invention, in at least some of the metallization layers of the BEOL stack, the elastic modulus of the dielectric material varies from one area of the layer to one or more other areas of the layer. In the method of the invention, a mask layer (21) is applied on the BEOL stack or on one of the metallization layers during fabrication of the stack, said mask layer covering portions of the stack area and exposing other portions of said area. Then a treatment is performed that changes the elastic modulus of the dielectric material in one or more of the metallization layers, but only in the areas not covered by the mask layer.
