Etching and Surface Modification of Polyimide in O2 -sf 6

Abstract Etch rates of Kapton H polyimide film in Sulfr hexafluoride- O2plasmas (0.25 torr) were studied as a function of the input gas mixture, the excitation frequency (25 kHz -450 kHz; 13.56 MHz) and the biasing mode.The treated surface was examined by X P S, SEM and contact angle measurement.Get price
