Insulating resin composition and semiconductor device using the same.

摘要

Insulating resin composition for a semiconductor device having a multilevell interconnection layers formed by the resin and having a superior planarizing capability relative to a lower interconnection layer is provided, which resin being a cured product of a polyamic acid ester oligomer obtained by reacting an aromatic diamine and/or a diaminosiloxane with an aromatic tetracarboxylic acid ester obtained by reacting an aromatic tetracarboxylic acid dianhydride with an alcohol or alcohol derivative.
