Abstract:
Disclosed is a negative photosensitive resin composition comprised of (A) an annual olefin resin containing repeating units represented by a general formula (1) (where R1, R2, R3 and R4 each represent an independent substituent group chosen from: a hydrogen atom, an alkyl group having 1-15 carbon atoms, an alkenyl group with 2-20 carbon atoms, a cycloalkyl group with 5-15 carbon atoms, an aryl group with 6-20 carbon atoms or an alkoxy group with 1-20 carbon atoms; or a hydrolysable silyl group, an alkoxycarbonyl group with 2-20 carbon atoms, a trialkylsiloxy carbonyl group with 4-20 carbon atoms, an alkyl carbonyl oxy group with 2-20 carbon atoms, an alkenyl carbonyl oxy group with 3-20 carbon atoms and an oxetanyl group; attached directly or via and jointly with an oxygen atom, a nitrogen atom or a sulphur atom), (B) a polyfunctional acrylic monomer and (C) a photoinitiator.
Abstract:
PROBLEM TO BE SOLVED: To provide a negative photo sensitive resin composition in which, when film thickness is increased, an interlayer insulating film having sufficiently superior characteristics such as resolution, translucency, thermal resistance, thermal discoloration resistance and solvent resistance, can be formed.SOLUTION: A negative photo sensitive resin composition includes (A) cycloolefin resin including repeating unit represented by the following formula (1), where R, R, Rand Rindependently represent substituent selected from hydrogen atom, alkyl group, alkenyl group, cycloalkyl group, aryl group or alkoxy group, or hydrolysis silyl group, alkoxycarbonyl group, trialkylsiloxycarbonyl group, alkylcarbonyloxy group, alkenylcarbonyloxy group and oxetanyl group, (B) multifunctional acryl monomer and (C) photo-polymerize initiator.
