    摘要: A method of forming a dielectric layer includes providing a substrate that has a copper region and a non-copper region. The substrate is etched to remove any copper oxides from the copper region. A dielectric cap is then selectively formed over the copper region of the substrate so that little or no dielectric cap is formed over the non-copper region of the substrate.
