发明名称 Acid generator compounds and photoresists comprising same
摘要 Acid generator compounds are provided that are particularly useful as a photoresist composition component. Acid generator compounds of the invention comprise 1) a cyclic sulfonium salt and 2) a covalently linked photoacid-labile group. In one aspect, thioxanthone acid generator compounds are particularly preferred, including acid generator compounds that comprise (i) a thioxanthone moiety; and (ii) one or more covalently linked acid labile-groups.

主权项 1. A photoresist composition comprising: (a) a polymer; and (b) an acid generator comprising: (i) a thioxanthone moiety; and(ii) one or more covalently linked acid labile-groups, wherein the acid generator exhibits a reduction potential of −0.9 to 0 V (vs. Ag/AgCl, cathodic peak potential) in a standard reduction potential assay.
