Two-directional plasma beam processing or mechanical rubbing was used to investigate the orientations of liquid crystal (LC) molecules on polyimide (PI) and hydrogenated amorphous carbon films. Two-directional plasma beam processing exhibits better homogeneity than two-directional mechanical rubbing in the LC alignment. In the two-directional mechanical rubbing treatment, grid-like texture appears...
This work investigates the effects of BF 2+ implantation on the oxidation resistance of copper films. The BF 2+ ions were implanted into Cu films through a 1000 a thick screen SiO 2 layer. We found that the oxidation resistance of Cu films can be significantly improved by BF 2+ implantation at appropriate conditions. In particular, BF 2+ ...
