Photoimageable compositions comprising polyquinoline polymer and photogenerable acid precursor

摘要

Photoimageable polyquinoline compositions comprise a polyquinoline polymer, a photogenerable acid precursor and optionally a photosensitizer. The composition is prepared by dissolving the polyquinoline polymer, photogenerable acid precursor and photosensitizer in a polar solvent to form a solution, coating the solution onto a substrate and thereafter removing the solvent to form a film. The film is exposed to light through a photo mask and developed by immersion in a selective solvent to yield a photopatterned dielectric film.
