Resumo

Pinanediol monosulfonate derivatives were used as acid amplifiers for chemically amplified ArF resists. A highly transparent acid amplifier free of aromatics improved the sensitivity of the resist without sacrificing. the resolution. Adding this acid amplifier to an ArF resist doubled its sensitivity, and 0.15μm line-and-space patterns were resolved.
