Document Type and Number:
WIPO Patent Application WO/2021/187481
Kind Code:
A1
Abstract:
Provided are: a photosensitive insulating film composition that gives a cured body for which the initial dielectric tangent is low and changes over time therein are small; a method for producing a cured relief pattern-equipped substrate using the photosensitive insulating film composition; and a semiconductor device provided with the cured relief pattern. A photosensitive insulating film-forming composition containing a polymer having a repeating unit structure represented by formula (1): [in formula (1), group A1 represents an aromatic heterocycle represented by (A1); group A2 represents an aromatic heterocycle represented by (A2); group A1 and group A2 may have crosslinkable substituents; group B1 represents an organic group having a crosslinkable substituent; and group B2 represents an organic group not having a crosslinkable substituent.] and a solvent.
