NOVEL PHENOL COMPOUNDS AND POSITIVE PHOTOSENSITIVE RESIN COMPOSITION INCLUDING THE SAME

摘要

PURPOSE: A positive type photosensitive composition is provided to improve physical properties and reliability of a membrane, and to boating excellent sensitivity, resolution, pattern formation, removal of residue, high elongation, high tensile strength, and low membrane shrinkage. CONSTITUTION: A phenol compound comprises one selected from a group consisting of a compound in chemical formula 1, a compound in chemical formula 2, and combinations thereof. A positive type photosensitive composition comprises 100.0 parts by weight of polybenzoxazole precursor, 5-100 parts by weight of a photosensitive diazoquinone compound, 1-30 parts by weight of a phenol compound, 0.1-30 parts by weight of a silane compound, and 50-300 parts by weight of a solvent. The polybenzoxazole precursor has the weight average molecular weight of 3,000-300,000.
