Composition for forming low dielectric constant insulating film, method of forming insulating film using the composition and electronic parts having the insulating film produced thereby

摘要

A composition for the formation of an insulating film comprising a low dielectric constant polymeric material and a sublimating material, which are dissolved in a solvent. Preferred low dielectric constant polymeric materials include polyaryl ethers. Preferred sublimating materials include silicone compounds having a closed stereostructure having atoms at its vertexes, such as those known as Si-T8 and Si-T12. A method of forming a low dielectric constant insulating film and electronic parts or components using an insulating film formed thereby are also disclosed.
