  • Patent number: 6140456
    Abstract: New starting materials and chemical processes will be used to make fluorinated poly(para-xylylenes) (F-PPX) and fluorinated poly(para-fluoroxylylenes) (F-PPFX). The processes will use some very low cost and readily available starting materials, catalysts, chemical reactors, transport polymerization (TP) systems, and chemical vapor deposition (CVD) systems commonly used for making F-PPX. New TP and CVD deposition systems will also be used to make F-PPX and F-PPFX. These polymers are used for the manufacture of low dielectric films with high thermal stability and are sufficiently strong to withstand planarization and polishing for the manufacture of integrated circuits.
