    摘要: A polymer comprising recurring units of formulae (1) and (2) wherein R1 and R3 are H or methyl, R2 and R4 are C1-15 alkyl, R5 to R8 are H, or R5 and R7, and R6 and R8 form trimethylene or 1,3-cyclopentylene and having a Mw of 1,000-500,000 is novel. A resist composition comprising the polymer as a base resin is sensitive to high-energy radiation, has excellent sensitivity, resolution and etching resistance and lends itself to micropatterning with electron beams or deep-UV.

    摘要: A polymer comprising recurring units of formulae (1), (2), (3) and (4) increases a dissolution rate in an alkali developer under the action of an acid. R1, R2, R3 and R6 are H or CH3, R4 and R5 are H or OH, X is a tertiary exo-alkyl group having a bicyclo[2.2.1]heptane framework, represented by any of formulae (X-1) to (X-4): wherein R7 is C1-C10 alkyl, and Y is a tertiary alkyl group having an adamantane structure. A resist composition comprising the inventive polymer has a sensitivity to high-energy radiation, improved resolution and minimized proximity bias and lends itself to micropatterning with electron beams or deep UV for VLSI fabrication.

    摘要: There is disclosed a resist composition which shows high sensitivity and high resolution on exposure to high energy beam, provides reduced Line Edge Roughness because swelling at the time of development is reduced, provides minor amounts of residue after development, has excellent dry etching resistance, and can also be used suitably for the liquid immersion lithography; and a patterning process using the resist composition. There can be provided a resist composition which comprises, at least, a polymer including repeating units represented by the following general formulae (a) and (b).
