Process for spin-on coating with an organic material having a low dielectric constant

摘要

A process for spin-on coating with an organic material having a low dielectric constant, which is suitable for a substrate. A dielectric base layer capable of protecting metal is formed on the substrate, an adhesive promoter layer is formed on the dielectric base layer, and the adhesive promoter layer is baked. A solvent is then used to clean the substrate and simultaneously to dissolve a part of the adhesive promoter layer in order to flatten the adhesive promoter layer. Afterwards, a layer of an organic material with a low dielectric constant is spin-on coated on the adhesive promoter layer, and the layer of an organic material with a low dielectric constant is baked and cured.
