Abstract

BPDA-PDA (3,3’,4,4’-biphenyl dianhydride-p-phenylenediamine) tetracarboxylic acid derived polyimide (PI) surface imidization is initiated at the 230°C cure step and reaches completion at the 300°C bake. Exposure of BPDA-PDA to CF₄ reactive ion etching (RIE) results in a highly fluorinated surface, as expected. Ar sputter exposure of this highly fluorinated surface causes a significant reduction in the fluorine concentration and deposition of metal from the sample pallet. Scanning electron microscopy and atomic force microscopy analyses show that CF₄ RIE treatment results in significant surface roughening of the polyimide, whereas Ar sputtering smoothens the virgin and the CF₄ RIE exposed polyimide.
