Abstract: A significant improvement in the alignment of a particle-beam-generated pattern relative to a pre-existing pattern present on a substrate has been accomplished using optical measurement to register the particle beam to the pre-existing pattern. Use of a position fiducial which can be accurately measured by both an optical microscope and a particle beam axis is used to align a pre-existing pattern with a particle-beam-generated pattern during writing of the particle-beam-generated pattern. Registration of the pre-existing pattern to the fiducial and registration of the particle beam axis to the fiducial periodically during production of the particle-beam-generated pattern continually provides an improvement in the overall alignment of the pattern being created to the pre-existing pattern on the substrate. The improved method of alignment can be used to correct for drift, or thermal expansion, or gravitational sag, by way of example.

Abstract: 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. Thereafter, the dielectric hard mask and the organic fill material are sequentially etched to form vias on the surface of the substrate, where the trenches are protected by the organic fill material from being etched. A bottom etch stop layer on the bottom of the vias is then etched and the organic fill material is striped. As a result, the invention provides good patterned profiles of the via and trench openings of a dual damascene structure.
