WebRefractive index – why is it important in PECVD? Refractive index is a good indicator of film composition, i.e. Si:N ratio or Si:O ratio. (If Si content is high, the refractive index will be high) It can be easily measured by ellipsometer or prism coupler, allowing rapid evaluation of film composition (and unifomrity of composition). WebFrom the fit, the complex refractive index versus photon energy as well as the thicknesses of the active layer and the interlayers are obtained.
