Abstract:
Modulation frequency and pulse duty cycle are two key parameters of pulsed VHF-PECVD technology. An experimental study on the microcrystalline silicon materials prepared by pulsed VHF-PECVD technology in high deposition rate is presented. And combining the diagnosis of plasma process with optical emission spectroscopy (OES), the dependence of microstructure and electrical properties of thin films on the pulse modulation frequency is discussed in detail.
