PHOTOSENSITIVE COMPOUND, PHOTOINTENSIFER COMPOSITION, MAKING THEREOF, PHOTORESIST COMPOSITION AND MAKING OF ARTICLE

摘要

The invention relates to new mixed ester photosensitive compounds and photosensitizer compositions comprised thereof. The photosensitive compounds and photosensitizer compositions are prepared by condensing phenolic compounds with a 1,2-naphthoquinonediazide-4-sulfonic acid halide and an organic acid halide in specific ratios. Photoresist compositions comprising the photosensitive compounds and photosensitizer compositions are also disclosed. The photosensitizer compositions exhibit excellent solution stability and resistance to precipitation when formulated in alkali-soluble resin photoresist compositions. The photoresist compositions have improved shelf life.
