Abstract: The present invention provides new photoresist compositions that comprise a resin binder, a photoactive component, particularly an acid generator, and a dye material that contains one or more chromophores that can reduce undesired reflections of exposure radiation. Preferred dye compounds are polymeric materials that include one or more chromophores such as anthracene and other polycyclic moieties that effectively absorb deep UV exposure radiation.

Abstract: 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 ?,?-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 ?,?-difluoroalkyl sulfonic acids.

Abstract: The present invention provides new photoresist compositions that comprise a resin binder, a photoactive component, particularly an acid generator, and a low molecular weight anthracene dye compounds. It has been found that these dye compounds can significantly reduce or even eliminate undesired reflections of exposure radiation, particularly deep U.V. exposure radiation such as 248 nm, as well as function as effective sensitizer compounds, enabling effective imaging at higher wavelengths, particularly I-line exposures.
