摘要:
Alicyclic methacrylate compounds having an oxygen substituent group on their α-methyl group, represented by formula (1), are novel wherein R1 is H or C1–C10 alkyl which may contain a halogen atom, hydroxyl group, ether bond, carbonyl group, carboxyl group or cyano group, and R2 is a monovalent C3–C20 organic group having an alicyclic structure. Polymers prepared from these alicyclic methacrylate compounds have improved transparency, especially at the exposure wavelength of an excimer laser, and improved dry etching resistance. Resist compositions comprising the polymers are sensitive to high-energy radiation, show a high resolution, allow smooth development, lend themselves to micropatterning, and are thus suitable as micropatterning material for VLSI fabrication

A polymerizable fluorinated compound having formula (2a) or (2b) wherein R1 and R2 are H or C1-C20 alkyl or fluoroalkyl, R3 is H, F or C1-C4 alkyl or fluoroalkyl, and R is H or a protective group is polymerized into a fluorinated polymer which is used as a base polymer to formulate a resist composition having transparency to laser light of wavelength≦300 nm, alkali development amenability, and dry etch resistance.
摘要:
Polymerizable fluorinated ester compounds having formula (1) or (2) are novel wherein R1 is H, methyl or trifluoromethyl, R2 is a divalent hydrocarbon group, R3 is H or a monovalent hydrocarbon group, or R2 and R3, taken together, may form a ring, R4 is H, OH or a monovalent hydrocarbon group, and R5 is an acid labile group. They are most useful as monomers to produce polymers for the manufacture of radiation-sensitive resist compositions.
摘要:
A composition comprising (A) a fluorinated polymer having k=0.01-0.4 and n=1.4-2.1 and (B) an aromatic ring-bearing polymer having k=0.3-1.2 is used to form an antireflective coating. The ARC-forming composition can be deposited by the same process as prior art ARCs. The resulting ARC is effective in preventing reflection of exposure light in photolithography and has an acceptable dry etching rate.
摘要:
A positive resist composition comprises a polymer comprising recurring units having a sulfonium salt incorporated therein as a base resin which becomes soluble in alkaline developer under the action of acid. The polymer generates a strong sulfonic acid upon exposure to high-energy radiation so as to facilitate effective scission of acid labile groups in the resist composition.
