According to a flexible thin film capacitor of the present invention, an adhesive film is formed on a substrate composed of at least one selected from the group consisting of an organic polymer and a metal foil, and an inorganic high dielectric film and metal electrode films are formed thereon. A metal oxide adhesive film can be used as the adhesive film. The adhesive film is formed in contact with the inorganic high dielectric film and at least one of the metal electrode films.

Flexible thin film capacitor and method for producing the same

A Pt/Ti film is formed on a substrate, and the Pt/Ti film is patterned in to a bottom electrode. Subsequently, a SrTiO film, that is, a dielectric film, is formed on the substrate by sputtering using a mixture of an Ar gas, an O gas and a N gas as a film forming gas. The SrTiO film is patterned into a capacitor dielectric film formed on the bottom electrode. A top electrode is then formed on the capacitor dielectric film. Since a N gas is used as the film forming gas in addition to an Ar/O gas, a SrTiO film with a high dielectric constant and small leakage can be formed at a low temperature. By using this SrTiO film, a thin film capacitor with high capacitance and good dielectric characteristics can be obtained.

The method and the apparatus of manufacturing the I-III-VI.sub.2 type chalcopyrite semiconductor thin films of the present invention control the film composition easily and improve the reproducibility of films by monitoring the composition of the films during forming the films. The apparatus comprise the substrate holder and heater which are in the vacuum chamber and Mo-coated glass substrate on which Cu(In,Ga)Se.sub.2 films are deposited. The change of the substrate temperature is monitored by the use of a heating element to heat the substrate by releasing a certain quantity of heat, a mechanism of measuring a temperature of the heated substrate. The change of power supplied is monitored by the use of a power source for the heating element to keep the substrate at a certain temperature and a mechanism of monitoring the change of the power supplied to the heating element. The changes in substrate temperature or power supplied can be correlated to the film composition.

This solar cell includes a substrate, a back electrode formed on the substrate, a p-type chalcopyrite semiconductor thin film formed on the back electrode, an n-type semiconductor thin film formed so as to constitute a pn junction with the p-type chalcopyrite semiconductor thin film, and a transparent electrode formed on the n-type semiconductor thin film. A material having a higher resistivity than the p-type chalcopyrite semiconductor is formed between the p-type chalcopyrite semiconductor thin film and the n-type semiconductor thin film. A thin film made of this material may be formed by deposition from a solution. For example, CuInS.sub.2 is formed on the surface of a p-type chalcopyrite based semiconductor such as CuInSe.sub.2 by contacting the surface of the semiconductor with a solution in which a salt containing group IIIb elements, an organic substance containing group VIb elements and acid are mixed.
