NEGATIVE PHOTOSENSITIVE POLYIMIDE COMPOSITION AND METHOD OF FORMING IMAGE FROM THE SAME

摘要

A negative photosensitive polyimide composition which is soluble in organic solvents, is excellent in adhesion, heat resistance, mechanical properties, and flexibility, and gives a highly sensitive negative photoresist which becomes alkali-soluble upon light irradiation. The composition comprises a photo-radical generator and a solvent-soluble polyimide showing negative photosensitivity in the presence of either an olefin or the photo-radical generator.
