Adhesion measurements of Cu sputter coated onto the photo-oxidized PFA surface results in failure within the PFA (cohesive failure)and not at the Cu-PFA interface.14aSURFACE MODIFICATION14aTEFLON+14aPFA14aCOPPER, VUV14aPHOTO-OXIDATION14aCOHESIVE FAILURE14aADHESION14aAR MICROWAVE PLASMA12aDasilva, W.12aEntenberg, A.12aKahn, B.12aDebies, T.12aTakacs, G.
