Document Type and Number:
Japanese Patent JP6245252
Kind Code:
B2
Abstract:
The present invention relates to a method for producing a polyimide insulating coating layer, the method comprising a step of:
applying a polyimide precursor composition to a substrate and baking the composition on the substrate,
wherein the polyimide precursor composition comprises a polyamic acid and a basic compound selected from the group consisting of imidazoles and amine compounds, and
wherein in the baking step,
the length of time for which the polyimide precursor composition is heated is 10 seconds to 180 seconds;
the average temperature increasing rate from 100°C to 280°C is 5°C/s or more; and
the highest heating temperature is 300°C to 500°C.
