英文摘要：

SiON becomes a kind of new functional material because it has many excellent mechanical and chemical properties such as high hardness, corrosion resistance, oxidization resistance. It is reported that the coating of SiON has many important applications in optical device. For example, it can be used as the protective layer of Edmund optics, touch panel of mobile phone, waveguide tube et al. the Mohs hardness of SiON is about 9H. In addition, the transmittance of the coating is 98% in the visible region. Lately, lots of researchers are interested in the biomedical applications of SiON coatings due to its favourable mechanical properties and the good hemocompatibility of the material. Such as hip implants, it can help patient recover soon because the coating is smooth and the Si–N and Si–O–N chemical bonding are more to the hydrophilicity than Si–O or Si–Si bonds. There is also lots of significant application of SiON films in the field of microelectronics. According to the reports, SiON has the inhibiting effect on hot-carrier injection, impurity diffusion and water vapor permeability. As the dielectric layer, SiON also possesses better electronic mobility and the trap densities of electron. So far, the main synthetic method of SiON is plasma enhanced chemical vapor deposition（PECVD） including inductive coupled plasma source（ICP）, capacitive coupled plasma source（CCP） and microwave electron cyclotron resonance（ECR）. It is found that selectivity of PECVD is bad along with the further study of it. In addition, the SiON dielectric layer contains impurities unavoidably, for example, it will affect the insulation and dielectric properties if adding H atom into the dielectric layer, which can restrict application in large scale integrated circuit. Helicon wave plasma source（HWP） comes to the notice of many researchers because of its high density（about 10~（13） cm~（-3）） at low pressure（0.1~10 Pa）. Chen said that ＂Interest in helicon discharges stems from their unusually high i
