High-{ital T}{sub {ital c}} Bi-Sr-Ca-Cu-O thin films were coated with electron-beam-evaporated SiO{sub 2}. The room-temperature resistivity of the coated films and their superconductivity onset and zero-resistance temperatures were not affected by the dielectric film. High-frequency capacitance-voltage studies did not show any modulation of space charge in the surface layer of the superconducting film. It is observed that the high-frequency (1 MHz) capacitance of the metal-insulator-superconductor structure has an appreciable temperature dependence.
