Title:
PROCESS FOR PRODUCING ONIUM SALT DERIVATIVE AND NOVEL ONIUM SALT DERIVATIVE
Document Type and Number:
WIPO Patent Application WO/2001/040167
Kind Code:
A1
Abstract:
A production process by which an onium salt derivative useful as, e.g., an acid generator in resists of the chemical amplification type can be synthesized in high yield. The process comprises reacting an onium salt derivative having a halogen anion or carboxylate anion with a sulfonic ester derivative or phosphoric ester derivative. Thus, an onium sulfonate derivative or onium phosphate derivative is obtained in high yield.
