摘要:
The present invention provides a chemically-amplified positive resist composition including a sulfonium salt capable of providing a pattern having an extremely high resolution with low line edge roughness, and also provides a resist patterning process using the same.The present invention was accomplished by a chemically-amplified positive resist composition including: (A) a salt represented by the following general formula (1); and (B) a resin containing a repeating unit represented by the following general formula (U-1) that dissolves by acid action and increases solubility in an alkaline developer, and a resist patterning process using the same.

Cyclooctadiene derivative of the following formula (1): ##STR1## wherein A.sup.1, A.sup.2, A.sup.3 and A.sup.4 each independently represent COOR.sup.5 (where R.sup.5 represents a hydrogen atom, a C.sub.1 -C.sub.10 alkyl group, a phenyl group, a C.sub.7 -C.sub.12 aralkyl group or CONR.sup.6 R.sup.7 (where R.sup.6 and R.sup.7 each independently represent a hydrogen atom, a C.sub.1 -C.sub.10 alkyl group or a phenyl group), or A.sup.1 and A.sup.2, and/or A.sup.3 and A.sup.4 may be combined together to represent group(s) of: ##STR2## in which X represents an oxygen atom or NR.sup.8 {where R.sup.8 represents a hydrogen atom, a C.sub.1 -C.sub.10 alkyl group or a phenyl group), R.sup.0, R.sup.1, R.sup.2, R.sup.3 and R.sup.4 each independently represent a hydrogen atom, a halogen atom, a hydroxyl group and an C.sub.1 -C.sub.10 alkyl group, the symbol ------ represents a single or double bond, and when it is a double bond, then R.sup.1 and R.sup.3 each independently may represent an oxygen atom; provided that the case where all of R.sup.0, R.sup.1, R.sup.2, R.sup.3 and R.sup.4 represent hydrogen atoms at the same time is excluded, and agrohorticultural fungicides, antimold agents and antithrombocytic agents containing said derivatives. The compounds have superior fungicidal activity, antimold activity and activity for preventing platelet aggregation, and are useful as an agrohorticultural fungicide, an antimold agent and an antithrombocytic agent.
