| 摘要 |
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.
