Filed: 1992-11-19
Abstract: PURPOSE:To provide heat resistant positive type photoresist composition excellent in sensitivity and resolution by mixing specified vinyl ether compound and compound showing acidity with the irradiation of active beam in polyimide precursor. CONSTITUTION:Heat resistant positive type photoresist composition contains polyimide precursor with structural units shown by formula I, vinyl ether compound shown by formula II or III and compound showing acidity with the irradiation of active beam. In formula I-III, R1 and R2 are quadrivalent and bivalent aromatic or aliphatic hydrocarbon remaining groups, R3 and R4 are aromatic hydrocarbon groups with one or more coupling, and (l), (m), (n) are 1 or greater integers. The polyimide precursor showing alkali solubility is decreased in solubility with carboxyl groups protected by polyvinyl compound.
