Integrated circuit structure

摘要

An interlayer dielectric multilayer film is formed by providing a boron nitride film as a protective film 34 between interlayer dielectric films 33 with a low relative dielectric constant which comprise organic coated films or porous films. The interlayer dielectric films 34 having a low relative dielectric constant are combined with the boron nitride film excellent in mechanical and chemical resistance, high in thermal conductivity and having a low relative dielectric constant, thereby achieving a low relative dielectric constant, while maintaining adhesion and moisture absorption resistance.
