Problems solved by technology

However, in the case of the conventional polyimide resin precursor composition, thermal imidization cannot be completed if the curing temperature is lowered, and various cured film physical properties decrease, so the lower limit of the curing temperature is 300°C about

[0321] (Regarding Examples 1 to 14, Examples 16 to 27, and Comparative Examples 1 to 5)

[0322] After the exposure, the alkaline developer (Developer, 2.38% aqueous solution of tetramethylammonium hydroxide) was used at 23°C for 30 seconds x 2 times, followed by rinsing with pure water to remove the residue of the coating film. unexposed part. Next, the above-mentioned patterned substrate was baked at 220° C. for 30 minutes in an oven replaced by nitrogen to cure it.
