摘要：

We confirmed that the density of a SiOF film was decreased by the addition of C2F6 as a fluorine source. Such a decrease in the density had the most significant effect on the water absorptivity. Densities of the films were controlled by increasing O-2 gas mixture ratios. From the TDS measurements of water desorption and the change in dielectric constants which occurred when the Blm was exposed to atmosphere, we confirmed that the densified films had lower water absorptivity.
