Method of forming positive polyimide patterns

A photosensitive polyimide precursor composition containing as main ingredients a poly(amic acid) wherein at least one molecular end is esterified with an alcohol, a compound containing carbon-carbon unsaturation having photoreactivity, and a photopolymerization initiator. The photosensitive polyimide precursor composition of the present invention can be prepared without the formation of any harmful by-product. When film formed from this composition is masked for patterning and then subjected to exposure and development using a developer, the amount of exposed portion dissolved in the developer until unexposed portion is dissolved off by the developer, is small and so it is possible to obtain a thick pattern. Further, by heat-treating this pattern, there can be obtained a thick polyimide pattern.
