摘要:
A sulfonic acid onium salt represented by the following formula (1) can be used as a superior radiosensitive acid generator for resist compositions. It is possible to form a good pattern by using a resist composition containing this sulfonic acid onium salt. In formula (1), R1 represents a monovalent organic group, and Q+ represents a sulfonium cation or iodonium cation.
