Abstract:
1. A photosensitive polymer composition, comprising: (a) a polymer selected from (i) polyimide precursors that contain repeating units of the following general formula (III): where R (ii) polyimides having substantially no amino group (—NH where R wherein the polymer has no group capable of forming a cross-linkage into a polyimide during heat-treatment at any end thereof; and (b) a compound that generates an acid when exposed to light and is capable of detaching the acid-protecting group from the protected acid group, wherein at least some of the ends of the component (a) are composed of a protected amino group with an end-protecting group, wherein said end-protecting group can be detached from the protected amino group by heat-treatment at 400° C. or less.
