    摘要: A method is provided for forming a film stack in which a first film including a first polymer is formed on a substrate. A second film, which can include a second polymer other than the first polymer, is formed to have an inner surface disposed on the first film. The second film can have a thickness at which a free energy of the second film would be negative if the second film were disposed directly on the substrate. Desirably, the resulting second film is substantially free of dewetting defects.

    摘要: A semiconductor structure and method of manufacturing the semiconductor structure, and more particularly to a semiconductor structure having reduced metal line resistance and a method of manufacturing the same in back end of line (BEOL) processes. The method includes forming a first trench extending to a lower metal layer Mx+1 and forming a second trench remote from the first trench. The method further includes filling the first trench and the second trench with conductive material. The conductive material in the second trench forms a vertical wiring line extending orthogonally and in electrical contact with an upper wiring layer and electrically isolated from lower metal layers including the lower metal layer Mx+1. The vertical wiring line decreases a resistance of a structure.

    摘要: An electrical fuse and a first dielectric layer thereupon are formed on a semiconductor substrate. Self-assembling block copolymers containing two or more different polymeric block components are applied into a recessed region surrounded by a dielectric template layer. The self-assembling block copolymers are then annealed to form a pattern of multiple circles having a sublithographic diameter. The pattern of multiple circles is transferred into the first dielectric layer by a reactive ion etch, wherein the portion of the first dielectric layer above the fuselink has a honeycomb pattern comprising multiple circular cylindrical holes. A second dielectric layer is formed over the circular cylindrical holes by a non-conformal chemical vapor deposition and sublithographic cavities are formed on the fuselink. The sublithographic cavities provide enhanced thermal insulation relative to dielectric materials to the fuselink so that the electrical fuse may be programmed with less programming current.

    摘要: Fully and uniformly silicided gate conductors are produced by deeply “perforating” silicide gate conductors with sub-lithographic, sub-critical dimension, nanometer-scale openings. A silicide-forming metal (e.g. cobalt, tungsten, etc.) is then deposited, polysilicon gates, covering them and filling the perforations. An anneal step converts the polysilicon to silicide. Because of the deep perforations, the surface area of polysilicon in contact with the silicide-forming metal is greatly increased over conventional silicidation techniques, causing the polysilicon gate to be fully converted to a uniform silicide composition. A self-assembling diblock copolymer is used to form a regular sub-lithographic nanometer-scale pattern that is used as an etching “template” for forming the perforations.
