ABSTRACT:
A material for an insulating film which comprises a copolymer obtained by reacting a polyamide having a specific structure and a reactive oligomer as a component forming the film; a coating varnish for an insulating film which comprises this material and an organic solvent; an insulating film which comprises a layer of a resin comprising as a main structure a polybenzoxazole which is obtained by treating the above material or the above coating varnish by heating so that condensation reaction and crosslinking reaction take place and has fine pores; and a semiconductor device which comprises an insulating interlayer film for multi-layer wiring comprising the insulating film and/or a surface protective film comprising the insulating film. Excellent electrical, thermal and mechanical properties are exhibited and a low permittivity can be achieved.
