    摘要： A semiconductor structure and a method for forming the same. The structure includes (a) a substrate which includes semiconductor devices and (b) a first ILD (inter-level dielectric) layer on top of the substrate. The structure further includes N first actual metal lines in the first ILD layer, N being a positive integer. The N first actual metal lines are electrically connected to the semiconductor devices. The structure further includes first trenches in the first ILD layer. The first trenches are not completely filled with solid materials. If the first trenches are completely filled with first dummy metal lines, then (i) the first dummy metal lines are not electrically connected to any semiconductor device and (ii) the N first actual metal lines and the first dummy metal lines provide an essentially uniform pattern density of metal lines across the first ILD layer.

    摘要： A method of forming a semiconductor device includes patterning a photoresist layer formed over a homogeneous semiconductor device layer to be etched; subjecting the semiconductor device to an implant process that selectively implants a sacrificial etch stop layer that is self-aligned in accordance with locations of features to be etched within the homogeneous semiconductor device layer, and at a desired depth for the features to be etched; etching a feature pattern defined by the patterned photoresist layer into the homogenous semiconductor device layer, stopping on the implanted sacrificial etch stop layer; and removing remaining portion of the implanted sacrificial etch stop layer prior to filling the etched feature pattern with a fill material.

    摘要： A non-photosensitive polymeric resist containing at least two immiscible polymeric block components is deposited on the planar surface. The non-photosensitive polymeric resist is annealed to allow phase separation of immiscible components and developed to remove at least one of the at least two polymeric block components. Nanoscale features, i.e., features of nanometer scale, including at least one recessed region having a nanoscale dimension is formed in the polymeric resist. The top surface of the polymeric resist is modified for enhanced etch resistance by an exposure to an energetic beam, which allows the top surface of the patterned polymeric resist to become more resistant to etching processes and chemistries. The enhanced ratio of etch resistance between the two types of surfaces provides improved image contrast and fidelity between areas having the top surface and the at least one recessed region.
