摘要

Fluorinated silicon dioxide films were prepared by liquid phase deposition method using hydrosilicofluoric acid and ammonium hydroxide aqua as sources. The quality of fluorinated silicon dioxide films can be improved by N_2 thermal annealing. It is in an attempt to evaluate the feasibility of this material as a candidate for inter-metal dielectrics in ULSIs. The obtained results were the relative dielectric constant of 3.2, and the leakage current density measured at the electric field of 1.5MV/cm about 1 x 10~(-7) A/cm~2 at the annealing temperature of 350℃. It has potential for inter-metal dielectric applications.
