    摘要: Disclosed is a method for dust-proofing of a photomask in the photolithographic processing of electronic devices, e.g., LSIs and liquid-crystal display panels, in which the photomask is covered with a pellicle having a frame-supported light-transmitting membrane made from a polyvinyl alcohol modified by silylating the hydroxy groups of the polyvinyl alcohol with triorganosilyl groups of the formula R.sub.3 Si--, in which R is a monovalent hydrocarbon group, e.g., alkyl, in a degree of substitution of at least 40%. The membrane of the pellicle is highly transparent to light of short wavelength in the ultraviolet region and excellently durable under prolonged irradiation with ultraviolet light not to cause yellowing or mechanical breaking.

    摘要: A rinse comprising a water-soluble polymer is suited for use in a lithographic process. In the lithographic process for the fabrication of semiconductor integrated circuits involving the exposure of resist to various types of radiation (e.g., UV, deep UV, vacuum UV, electron beams, x-rays, and laser beams), the invention can prevent resist insoluble components from generating on and attaching to the resist film or substrate, and if insoluble components attach, can effectively remove the insoluble components, thus avoiding a lowering of production yield by defects resulting from the insoluble components.

    摘要: A water-soluble coating composition for forming a layer to be placed on the upper surface of a resist is provided without use of Freons. The material includes an aqueous solution containing a) at least one water-soluble polymer selected from the group consisting of poly(N-vinylpyrrolidone) homopolymers and water-soluble copolymers of N-vinylpyrrolidone and other vinyl monomers, b) at least one fluorine-containing organic acid, and c) at least one amino acid derivative. The film formed through use of the material of the invention serves as both an anti-reflective film and a protective film. The material of the present invention provides a number of advantages in the formation of resist patterns, including excellent film-forming properties, excellent dimensional accuracy and aligning accuracy, simple and easy handling, high productivity, and good reproducibility.

    摘要: A chemically amplified positive resist composition contains (A) an organic solvent, (B) a base resin, (C) a photoacid generator, and optionally, (D) a dissolution rate regulator. The base resin (B) is a hydroxystyrene copolymer having different acid labile groups and Mw of 3,000-300,000. The resist composition is highly sensitive to actinic radiation such as deep-UV, electron beam and X-ray, can be developed with aqueous base to form a pattern, and is thus suitable for use in a fine patterning technique.
