Abstract: A high quality transparent SiC thin film can be deposited on the surface of a plastic material at low temperature utilizing Electron Cyclotron Resonance (ECR) Plasma CVD techniques, thereby enhancing surfacial hardness without spoiling designability. A magnetic field is applied to a plasma generating chamber by means of a surrounding magnetic coil. Microwaves are then introduced into the plasma generating chamber. Further, an upstream gas is introduced into the plasma generating chamber. ECR plasma is thus generated. A downstream gas is then supplied to the chamber from an inlet. Furthermore, the ECR plasma is passed through a mesh placed between the inlet and a polymer base material or between the plasma generating chamber and the inlet. Accordingly, a SiC film is deposited on a surface of a polymer base material.
