    摘要: A resist composition and a process for forming a resist pattern using a resist composition are disclosed. The present composition includes 100 parts by weight of a copolymer of a 2-norbornene-2-substituent unit and an acrylic acid ester unit of the formula I; ##STR1## wherein, X is a cyano or chloro group, R is tert-butyl, dimethylbenzyl, or tetrahydropyranyl, m is an integer of 9 to 2390, and n is an integer of 21 to 5180, and 1 to 20 parts by weight of a photo acid generator. A finely-resolved resist pattern with high sensitivity and good dry etch resistance is obtained by the present composition and present process for forming the resist pattern.

    摘要: Alkali-developable, chemically amplified resist composition which comprises an alkali-insoluble, film-forming compound having a structural unit containing a protected alkali-soluble group in which unit a protective moiety of said protected alkali-soluble group is cleaved upon action of an acid generated from a photoacid generator used in combination with said compound, thereby releasing a 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 is particularly suitable for excimer laser lithography using an alkaline developer, and the formed resist patterns can exhibit a high sensitivity and excellent dry etch resistance without swelling.

    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.
