    摘要： A radiation-sensitive resin composition comprising: (A) an alkali insoluble or scarcely alkali-soluble resin having an acid-dissociable protecting group of the following formula [I], wherein R1 groups are monovalent alicyclic hydrocarbon groups or alkyl groups, provided that at least one of the R1 groups is the monovalent alicyclic hydrocarbon group, or any two of the R1 groups and the carbon atom form a divalent alicyclic hydrocarbon group, (B) a photoacid generator, and (C) propylene glycol monomethyl ether acetate, &ggr;-butyrolactone, and cyclohexanone as solvents. The resin composition is useful as a chemically-amplified resist for microfabrication utilizing deep ultraviolet rays and exhibits excellent film thickness uniformity and storage stability.

    摘要： A radiation-sensitive resin composition that provides a resist coating film in a liquid immersion lithography process is provided, the radiation-sensitive resin composition being capable of exhibiting a great dynamic contact angle during exposure, whereby the surface of the resist coating film can exhibit a superior water draining property, and the radiation-sensitive resin composition being capable of leading to a significant decrease in the dynamic contact angle during development, whereby generation of development defects can be inhibited, and further shortening of a time period required for change in a dynamic contact angle is enabled. A radiation-sensitive resin composition including (A) a polymer having a structural unit (I) represented by the following formula (1), and (B) a radiation-sensitive acid generator.

    摘要： A positive-tone radiation-sensitive resin composition comprising: (A) a low molecular weight compound having at least one amino group in which the nitrogen atom has at least one hydrogen atom bonded thereto and at least one of the hydrogen atoms is replaced by a t-butoxycarbonyl group, (B) a photoacid generator, and (C-1) a resin insoluble or scarcely soluble in alkali which is protected by an acid-dissociable group and becomes soluble in alkali when the acid-dissociable group dissociates or (C-2) an alkali-soluble resin and an alkali solubility control agent is disclosed. Also disclosed is a negative-tone radiation-sensitive resin composition comprising the low molecular weight compound (A), the photoacid generator (B), an alkali-soluble resin (D), and a compound capable of crosslinking with the alkali-soluble resin in the presence of an acid(E). The composition are useful as a chemically amplified resist which effectively responds to various radiations, exhibits superior sensitivity and resolution, forms fine patterns at a high precision and in a stable manner even if the patterns are isolated line patterns.
