Abstract
A low RC delay interconnection pattern is formed with a low resistivity metal, such as copper, and a low dielectric constant material, such as organic polymers. An intermediate bonding layer is formed between the low resistivity metal and low dielectric constant material employing an adhesion promoter, such as a silane-based adhesion promoter. The adhesion promoter can be applied between the metal and dielectric layers or incorporated in the dielectric layer.
