Etching and Surface Modification of Polyimide in O2 -gaz sf6

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. The ion and neutral species of the plasma were sampled and analyzed by mass spectrometry.A proposed kinetic analysis of the etching mechanism is in good agreement with the experimental data.Get price

Temperature influence on etching deep holes with gaz sf6/O2

Jun 14, 2002 · A cryogenic sf6 gas/O2plasma process has been used to investigate the etching of deep holes in silicon wafers. The influence of crystallographic and aspect ratio dependence of the etch rate on the holes profile have been explored. It was found that wafer temperature, during the etching process, played a crucial role in controlling the anisotropy and deteriorative faceting due to crystal orientation dependent etching.Get price
