    • 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.
    • 作为主要成分的感光性聚酰亚胺前体组合物,其中至少一个分子末端用醇酯化,含有具有光反应性的碳 - 碳不饱和键的化合物和光聚合引发剂的聚(酰胺酸)。 可以制备本发明的光敏聚酰亚胺前体组合物,而不会形成任何有害的副产物。 当由该组合物形成的膜被掩模以进行图案化,然后使用显影剂进行曝光和显影时,溶解在显影剂中的暴露部分的量直到未曝光部分被显影剂溶解掉,因此可以获得 厚图案。 此外,通过热处理该图案,可以获得厚的聚酰亚胺图案。

    • The present invention relates to a method of forming positive polyimide patterns which includes a process wherein a film of a composition of actinic radiation-sensitive polyimide precursor is formed on a substrate which is selectively exposed to an actinic radiation, then such a treatment is applied to the film that the film in unexposed portion attains higher degree of curing than the film in exposed portion after the exposure, and the film is removed from the exposed portion. According to the invention, such an unexpected effect can be achieved as a positive polyimide pattern can be formed by using a composition of actinic radiation-sensitive polyimide precursor which has only been used in forming negative patterns. According to the invention, the positive polyimide pattern can be formed easily and the pattern obtained has excellent performance.
