Abstract:
1. A method for forming a semiconductor structure, comprising: forming a dielectric layer comprising adjacent first and second dielectric regions on a substrate and comprising a curable material; forming a patterned light-cutting layer on the second dielectric region, curing the first dielectric region, wherein during curing the first dielectric region, the second dielectric region is covered by the patterned light-cutting layer; etching a portion of the second dielectric region to form an opening and leave a remaining portion of the second dielectric region; forming another patterned light-cutting layer on the cured first dielectric region; and curing the remaining portion of the second dielectric region after the etching step, wherein during curing the remaining portion of the second dielectric region, the cured first dielectric region is covered by the another patterned light-cutting layer.
