Abstract :
This study attempts to formulate dielectric properties of SiO2 films deposited by hydrochloric acid catalyzed sol-gel solution. This solution, with H2O:TEOS ratio between 10 and 15, is reported forming high density, small pore size film needing a low sintering temperature. Moreover, carbon in this kind of film is also easier to be burn off than that in the base catalyzed films. To elucidate the mechanism of dielectric dispersion in low temperature (800°C) annealed samples, chemical composition and physical structure of the annealed oxide are analyzed. In addition, the effect of environment moisture is also investigated
