The study on the electrical property shows that its dielectric property decreases with the slowly increase of frequency in dry state; in hygrometric state (52.9%), the dielectric property grows obviously and declines swiftly with the increase of frequency; and it tends to be stable when the frequency is over 10^4Hz. The specific resistance decreases linearly with the increase of the frequency.

It indicated that the multiple-layered films were mainly composed by C-F, C=C and Si-O bonging, a little Si-C and Si-F bonding were also existed because of history effect. The bondgap were calculated as 2.7eV. The dielectric constant of the multiple-layered films was close relative to the thickness of the covering layer-SiOx, so the thickness had better be reduce. The bonding configurations of multiple-layered films had no evident changes after 400癈 annealing, the thickness raise very little and the dielectric constant increase 8%. Compared with one-layered a-C:F films prepared in the same conditions, the SiOx/a-C:F/SiOx multiple-layered films had a better thermal stability.
