Abstract
An apparatus including a contact point on a substrate; a first dielectric layer comprising a material having a dielectric constant less than five formed on the contact point, and a different second dielectric layer formed on the substrate and separated from the contact point by the first dielectric layer. Collectively, the first and second dielectric layers comprise a composite dielectric layer having a composite dielectric constant value. The contribution of the first dielectric layer to the composite dielectric value is up to 20 percent. Also, a method including depositing a composite dielectric layer over a contact point on a substrate, the composite dielectric layer comprising a first material having a dielectric constant less than 5 and a second different second material, and forming a conductive interconnection through the composite dielectric layer to the contact point.
