  • Patent number: 7749895
    Abstract: A method for fabricating a semiconductor device includes forming an interlayer insulating film over a semiconductor substrate. The interlayer insulating film is selectively etched to form a hole defining a storage node region. A lower electrode is formed in the hole. A support layer is formed over the lower electrode. The support layer fills an upper part of the hole and exposes the interlayer insulating film. A dip-out process is performed to remove the interlayer insulating film. The supporting layer is removed to expose the lower electrode. A dielectric film is formed over the semiconductor substrate including the lower electrode. A plate electrode is formed over the semiconductor substrate to fill the dielectric film and the lower electrode.

  • Patent number: 7674708
    Abstract: A method for forming a fine pattern of a semiconductor device overcomes resolution limits of exposure equipment. The method includes forming a first photoresist pattern over an underlying layer formed over a semiconductor substrate. An amorphous carbon film and a second photoresist film are sequentially deposited over the first photoresist pattern. The second photoresist film and the amorphous carbon film are planarized to expose the first photoresist pattern. A thick portion and a thin portion of the amorphous carbon film is formed. The first photoresist pattern and the second photoresist film are removed. Etching is performed on the thin portion of the amorphous carbon film and the underlying layer using the thick portion of the amorphous carbon film as an etch mask. The thick portion of the amorphous carbon film is removed to expose a fine pattern of the underlying layer.

    Abstract: Disclosed herein are a liquid composition for immersion lithography and a lithography method using the composition. The liquid composition includes at least one nonionic surfactant selected from the group comprising of a polyvinyl alcohol, a pentaerythritol-based compound, a polymer containing an alkylene oxide, and a compound represented by Formula I: wherein R is a linear or branched, substituted C1-C40 alkyl, and n is an integer ranging from 10 to 10,000. The surface tension of the liquid composition is reduced by the nonionic surfactant, thereby solving the problem that the liquid composition is not completely filled or is partially concentrated on a wafer having a fine topology and removing micro bubbles between the photoresist film and the liquid composition.

  • Patent number: 7329477
    Abstract: The present invention provides a process for using an amine contamination-protecting top-coating composition. Preferably, the amine contamination-protecting top-coating composition of the present invention comprises an amine contamination-protecting compound. Useful amine contamination-protecting compounds include amine derivatives; amino acid derivatives; amide derivatives; urethane derivatives; urea derivatives; salts thereof; and mixtures thereof. The amine contamination-protecting top-coating composition of the present invention reduces or eliminates problems such as T-topping due to a post exposure delay effect and/or difficulties in forming a fine pattern below 100 nm due to acid diffusion associated with conventional lithography processes involving a photoresist polymer containing an alicyclic main chain using a light source, such as KrF (248 nm), ArF (193 nm), F2 (157 nm), E-beam, ion beam and extremely ultraviolet (EUV).
