ABSTRACT:
Fluorinated polymeric composition exhibiting low dielectric constant and a low coefficient of thermal expansion containing a fluorinated polymeric material and a silica and/or quartz filler having a mean particle size of no greater than 7 microns, and use thereof to form a substrate having vias therein. Layers of the above composition are obtained by applying the composition to a substrate and then heating the composition to a temperature sufficient to cause the composition to fuse.
