The Role Of Negative Bias
Aug 07, 2024| The role of negative bias
1. Increase the energy of charged particles in the vacuum plasma, bombard and clean the surface of the plated workpiece, so that the surface of the workpiece is affected by high-energy particles to get a new surface, so as to improve the binding force of the subsequent deposited film. By biased bombardment, a transition metal layer compatible with both is formed between the film layer and the matrix, so as to facilitate the bond between the film layer and the matrix. 3. Depending on the voltage output polarity or mode to change the deposition rule, adjust the film color and performance. 4. Through the bombardment of charged ions, the substrate has a heating effect. 5. Removing the adsorbed gas and oil on the substrate is conducive to improving the bond strength of the film layer. 6. Activate the substrate surface. 7. It can purify large particles in Arc Ion Plating.
