Patent ID: 8637151

Claim:
An interlayer dielectric film with a carrier material, comprising: a carrier material including a metal foil or a resin film and having a surface; and an interlayer dielectric film provided on the surface of said carrier material, comprising: a base material having a thickness of 8 μm to 20 μm; and a resin impregnated into the base material, the resin having a property so as to make the interlayer dielectric film have an elongation percentage in a planar direction of 0.05% or less as determined from 50° C. to 260° C. by a thermomechanical analysis method when the resin is impregnated into the base material and cured at 170° C. for one hour under a pressure of 30 kgf/cm 2 , and the resin containing a bisphenol-A epoxy resin or a bisphenol-F epoxy resin, and a naphthalene epoxy resin.
