Etching and Surface Modification of Polyimide in O2 -insulating gas

Etch rates of Kapton H polyimide film in sf6 gas- 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

Plasma etching of Si and SiO2 in sf 6–O2 mixtures: Journal of

Jun 04, 1998 · With an SF 6 ‐O 2 mixture in the absence of silicon, the final reaction products are F 2, SOF 4, and SO 2 F 2. The product distribution was unaffected by small SiO 2 substrates. When Si is etched, SiF 4 is the only stable silicon‐containing etch product and SOF 2 is formed in oxygen‐poor mixtures. Rapid etch rates (≳10 4 Å/min for Si) can be obtained with a high selectivity in favor of silicon (Si:SiO 2 ≳40:1); thus SF 6 ‐O 2 mixtures may represent an attractive alternative toGet price
