    摘要: A method of forming a thin film is provided in which a film having a first thickness is deposited over a substrate, wherein the first thickness is greater than a thickness at which the initially deposited film begins to dewet from the substrate. The initially deposited film is then stabilized to form a stabilized film. Thereafter, the stabilized film is then thinned to a second thickness, such that the resulting film now has a smaller thickness than the thickness at which the initially deposited film would begin to dewet from the substrate. However, as a result of the prior stabilization, the reduced thickness film remains 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: 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 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 method and apparatus are provided for improving the focusing of a substrate such as a wafer during the photolithography imaging procedure of a semiconductor manufacturing process. The invention is particularly useful for step-and-scan system and the CD of two features in each exposure field are measured in fields exposed at varying focus to form at least two Bossung curves. Exposure focus instructions are calculated based on the intersection point of the curves and the wafer is then scanned and imaged based on the calculated exposure focus instructions. In another aspect of the invention, when multiple wafers are being processed operational variances may cause a drift in the focus. The focus drift can be easily corrected by measuring the critical dimension of each of the features and comparing the difference to determine if any focus offset is needed to return the focus to the original calculated focus value.

    摘要: An opening in a substrate is formed, e.g., using optical lithography, with the opening having sidewalls whose cross section is given by segments that are contoured and convex. The cross section of the opening may be given by overlapping circular regions, for example. The sidewalls adjoin at various points, where they define protrusions. A layer of polymer including a block copolymer is applied over the opening and the substrate, and allowed to self-assemble. Discrete, segregated domains form in the opening, which are removed to form holes, which can be transferred into the underlying substrate. The positions of these domains and their corresponding holes are directed to predetermined positions by the sidewalls and their associated protrusions. The distances separating these holes may be greater or less than what they would be if the block copolymer (and any additives) were to self-assemble in the absence of any sidewalls.

    摘要: The present invention provides a method of forming a threshold voltage adjusted gate stack in which an external acid diffusion process is employed for selectively removing a portion of a threshold voltage adjusting layer from one device region of a semiconductor substrate. The external acid diffusion process utilizes an acid polymer which when baked exhibits an increase in acid concentration which can diffuse into an underlying exposed portion of a threshold voltage adjusting layer. The diffused acid reacts with the exposed portion of the threshold voltage adjusting layer providing an acid reacted layer that can be selectively removed as compared to a laterally adjacent portion of the threshold voltage adjusting layer that is not exposed to the diffused acid.
