Working Pressure Effect on the Microstructure and Electric Resistivity of SiC Films Produced by MF Magnetron Sputtering

Article Preview

Abstract:

SiC films were prepared by mid-frequency (MF) magnetron sputtering with sintering SiC target on monocrystalline Si(100) substrate. SEM and XRD were used to investigate the surface morphology and microstructure of SiC films changing with working pressure. Results show that the resistivity value of 4H-SiC is larger than that of 3C-SiC and when working pressure is 0.3Pa, the film is mainly based on 3C-SiC, when pressure is 0.6Pa, the film is mainly based on 4H-SiC.
