    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.

    摘要: A film stack is provided in which a first film including a first polymer directly contacts a surface of a substrate at which a given material is exposed. A second film, which can include a second polymer other than the first polymer, is formed to have an inner surface contacting 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 film stack and method of forming a film stack are provided in which a first film is disposed on a substrate and a second film has an inner surface disposed on the first film. The second film has a thickness smaller than a reference thickness at which the second film would begin to dewet from the substrate if the second film were disposed directly on the substrate. However, the second film is substantially free of dewetting defects because it is disposed overlying the first film which has a first Hamaker constant having a negative value with respect to the substrate.

    摘要: Disclosed is a method that deposits an aqueous material having a pH between approximately 10 and 11 in a first opening and on an oxide hard mask, deposits an organic material on the aqueous material, and patterns a photoresist over the organic material. The invention then etches the organic material and the aqueous material through the photoresist to form a second opening above the first opening and forms a polymer along sidewalls of the second opening. The invention can then perform a wet cleaning process using an alkali solution having a pH between approximately 10 and 11 to remove the aqueous material from the first opening. By utilizing an alkali aqueous (water-based) material having a pH of approximately 10-11, the invention can use a fairly low pH wet etch (pH of approximately 10-11) to completely remove the aqueous solution from the via, thereby eliminating the conventional problem of having residual organic material left within the via.

    摘要: Methods are presented of forming sub-lithographic patterns using double exposure. One method may include providing a photoresist layer over a layer to be patterned; exposing the photoresist layer using a first mask having a first opening; developing the photoresist layer to transfer the first opening into the photoresist layer, forming a boundary in the photoresist layer about the transferred first opening that is hardened; exposing the photoresist layer using a second mask having a second opening that overlaps the boundary; and developing the photoresist layer to transfer the second opening into the photoresist layer, leaving the boundary, wherein the boundary has a sub-lithographic dimension.

    摘要: A second photoresist having a second photosensitivity is formed on a substrate. A first photoresist having a first photosensitivity, which is greater than second photosensitivity, is formed on the second photoresist. Preferably, the first photoresist is a gray resist that becomes transparent upon exposure. At least one portion of the first photoresist is lithographically exposed employing a first reticle having a first pattern to form at least one transparent lithographically exposed resist portion, while the second photoresist remains intact. The second photoresist is lithographically exposed employing a second reticle including a second pattern to form a plurality of lithographically exposed shapes in the second photoresist. The plurality of lithographically exposed shapes have a composite pattern which is the derived from the second pattern by limiting the second pattern only within the area of the at least one transparent lithographically exposed resist pattern.
