| titleOfInvention | Positive Photosensitive Polyimide Precursor Composition |
| abstract | The present invention relates to a positive photosensitive polyimide precursor composition comprising a hydroxylated polyimide precursor and the following photosensitive compound (a) or (b).n n n (a) Phenolic compounds having a dipole moment of at least 0.1 dibi and at most 1.6 dibi include a compound esterified with naphthoquinone diazide sulfonic acid.n n n (b) The phenolic compound represented by following formula (8) contains the compound esterified by naphthoquinone diazide sulfonic acid, and / or the phenolic compound represented by following formula (8), and naphthoquinone diazide sulfonic acid ester.n n n <Formula 8>n n n n n n n n Wherein R 22 , R 24 , R 26 , R < 27> represents any of a hydrogen atom, the alkyl group, alkoxyl group, carboxyl group, and ester group chosen from C1-C8. R 25 represents at least one hydroxyl group, and otherwise, a hydrogen atom and an alkyl group selected from 1 to 8 carbon atoms. aa, bb, cc, dd represent the integer of 0-3. However, aa + bb ≦ 5, bb + dd ≦ 5, and aa + bb> 0. ee represents an integer of 1 to 3.)n n n Positive photosensitive polyimide composition, naphthoquinone diazide sulfone, phenolic compound, exposure |
