Method for forming low dielectric constant fluorine-doped layers










Image Number 13 for United States Patent #7910475.

A method for forming a semiconductor device is provided. In one embodiment, the method includes providing a semiconductor substrate with a surface region. The surface region includes one or more layers overlying the semiconductor substrate. In addition, the method includes depositing a dielectric layer overlying the surface region. The dielectric layer is formed by a CVD process. Furthermore, the method includes forming a diffusion barrier layer overlying the dielectric layer. In addition, the method includes forming a conductive layer overlying the diffusion barrier layer. Additionally, the method includes reducing the thickness of the conductive layer using a chemical-mechanical polishing process. The CVD process utilizes fluorine as a reactant to form the dielectric layer. In addition, the dielectric layer is associated with a dielectric constant equal or less than 3.3.
