    摘要: A resist composition comprises a base polymer which changes its alkali solubility under the action of an acid, and an additive copolymer comprising recurring units (a) and (b). R1 is F or CF3, R2 and R3 are H or alkyl or form a ring, R4 is H or an acid labile group, R5 to R6 are H, F, or alkyl, or two of R5 to R8 may together form a ring, m=0 or 1, 0.2≦a≦0.8, and 0.1≦b 0.6. A resist film of the composition has good barrier property against water so that leaching of the resist film with water is controlled, minimizing a change of pattern profile due to leach-out.

    摘要: In an immersion lithography process, a pattern is formed by forming a photoresist layer on a wafer, forming a protective coating on the photoresist layer from a resist overcoat material, exposing the layer structure to light in water, and developing. A water-insoluble, alkali-soluble material is used as the resist overcoat material.

    摘要: A resist protective coating material is provided comprising a polymer having a partial structure of formula (1) wherein R0 is H, F, alkyl or alkylene, and R1 is fluorinated alkyl or alkylene. In a pattern-forming process, the material forms on a resist film a protective coating which is water-insoluble, dissolvable in alkaline developer and immiscible with the resist film, allowing for effective implementation of immersion lithography. During alkali development, development of the resist film and removal of the protective coating can be simultaneously achieved.

    摘要: An additive polymer comprising recurring units of formula (1) is added to a resist composition comprising a base resin, a photoacid generator, and an organic solvent. R1 is hydrogen or methyl, R2 is alkylene or fluoroalkylene, and R3 is fluoroalkyl. The additive polymer is highly transparent to radiation with wavelength of up to 200 nm. Water repellency, water slip, acid lability, hydrolysis and other properties of the polymer may be adjusted by a choice of polymer structure.
