Abstract
A semiconductor device having electronic circuitry formed in a semiconductor substrate (11) and separated from an overlying metal interconnect layer (18,18') using a fluorinated polymer dielectric (14,14') . The fluorinated polymer layer (14,14') may be formed directly on metallic surfaces, or formed on a semiconductor or non-metallic surface using an adhesion promoter (13,13'). Once formed, the fluorinated polymer layer (14,14') can be patterned to provide vias, and covered with a patterned metal interconnect layer (18,18') .
