摘要： Alkali-developable, chemically amplified resist composition which comprises an alkali-insoluble compound having a structural unit containing a protected alkali-soluble group in which unit a protective moiety of said protected alkali-soluble group contains an alicyclic hydrocarbon group having bonded to a carbon atom thereof a —CH2—R1′ group wherein R1′ is methyl, ethyl, propyl or isopropyl, and said alkali-soluble group is cleaved upon action of an acid generated from a photoacid generator used in combination with said compound, thereby releasing said protective moiety from the alkali-soluble group and converting said compound to an alkali-soluble one, and a photoacid generator capable of being decomposed upon exposure to a patterning radiation to thereby produce an acid capable of causing cleavage of said protective moiety. The resist composition can exhibit a high sensitivity (not more than 5 mJ/cm2) and therefore is particularly suitable for ArF lithography and also can exhibit stable patterning properties.

摘要： The present invention discloses a chemically amplified resist composition that is able to form a resist pattern that can be exposed in short wavelength regions, has good transparency, sensitivity, dry-etch resistance and resolution, while also exhibiting excellent adhesion to the substrate. This chemically amplified resist composition comprises: the combination of a base resin comprised of a polymer that is itself insoluble in a basic aqueous solution and contains at least (A) a monomer unit I having carboxylic acid or phenol protected with a specific protective group, and (B) a monomer unit II having an ester group or ether group that contains a cyclic carbonate structure, and can become soluble in a basic aqueous solution when the protective group of the monomer unit I is deprotected by the effect of the acid; and, a photo acid generator capable of generating an acid that can provoke deprotection of the protective group of monomer unit I when decomposed by absorption of imaging radiation.
