Abstract
A photosensitive polyimide composition, a polyimide film, and a semiconductor device using the same are disclosed. The photosensitive polyimide composition can be cured by heating. A polyhydroxyimide is used as a base resin and can be mixed with a photoacid generator and a cross-linking agent having two or more vinylether groups. A film of the photosensitive polyimide composition can be developed by treatment with an alkaline aqueous solution. Embodiments of the invention enable improvement in production yield and reliability in a highly-integrated memory semiconductor packaging processes.
