Abstract: A thin film capacitor composed of a hybrid dielectric thin film that is sandwiched by a pair of electrodes. The hybrid dielectric thin film is obtained by complexing or accumulating first and second regions. The first region is derived from an ion plating source and the second region is derived from another ion plating source containing an auxiliary material to be coupled with the first region, both being obtained through an ion plating process. The use of the auxiliary material ensures a pinhole-free hybrid dielectric thin film.

Abstract: A conductive thin film is deposited on the surface of plastic film moving at high velocity by ion-plating using a pressure-gradient discharge. The moving velocity of the substrate film is as high as 8 to 30m/min. A conductive, thin film composed of indium oxide, tin oxide, TTD and similar substances is deposited on the plastic film, at a pressure of 1.times.10.sup.-5 to 1.times.10.sup.-1 Torr and a discharge voltage of 50 to 100 V.
