专利号:US-6849374-B2 优先权日:2000-11-03 标题:Photoacid generators and photoresists comprising same 发明人:CAMERON JAMES F; ZYDOWSKY THOMAS M 权利人:SHIPLEY CO LLC 摘要:This invention relates to new photoacid generator compounds and photoresist compositions that comprise such compounds. In particular, the invention relates to photoacid generator compounds that generate an α,α-difluoroalkyl sulfonic acid upon exposure to activating radiation. Positive- and negative-acting chemically amplified resists that contain such PAGs are particularly preferred. The invention also includes methods for synthesis of such PAGs and α,α-difluoroalkyl sulfonic acids.
