Plasma surface treatment is an effect method to modify the surface chemistry of a plastic substrate without affecting the nature of the substrate itself .In this there, we use high frequency SF6 plasma generated by Electron Cyclotron Resonance (ECR) to modify the surface properties of a Poly ethylene terephthalate (PET) substrate. We found that the PET surface properties were strongly related to the gas pressure, RF power and reaction time, In addition, by masking on parts of the sample surface, both by hydrophobic and hydrophilic surfaces can be obtained in a single process. The hydrophilic is formed because of large amount of oxygen atoms reacting to the masking areas of the sample surface after the sample was exposed to the atmosphere. The difference of the measured water contact angle of hydrophobic and hydrophilic surface is larger than 100 degree.
