Photosensitive polymer composition, method for forming relief patterns, and electronic parts |
摘要 |
Disclosed are a photosensitive polymer composition comprising (a) a polymer soluble in an aqueous alkaline solution, (b) an o-quinonediazide compound, and (c) a dissolution inhibitor for the component (a) in an aqueous alkaline solution; a method of using the composition for forming relief patterns; and electronic parts having, as a passivating film or an interlayer insulating film, the relief pattern as formed in the method. The composition has high sensitivity, and gives fine relief patterns having a good profile. |
