The invention provides methods and apparatuses for fabricating a dual damascene structure on a substrate. First, trench lithography and trench patterning are performed on the surface of a substrate to etch a low-k dielectric material layer to a desired etch depth to form a trench prior to forming of a via. The trenches can be filled with an organic fill material and a dielectric hard mask layer can be deposited. Then, via lithography and via resist pattering are performed.
