Abstract
The present disclosure relates to a passivation layer comprising a photocrosslinked fluoropolymer and a process for forming the layer. Passivation layers comprising the crosslinked fluoropolymer have low dielectric constants, low water absorptivity and are able to be photoimaged so as to provide the very fine features needed for modern electronic equipment.
