A thin film capacitor includes a first capacitor composed of a ferroelectric film and a supplementary second capacitor composed of the ferroelectric film surrounding the first capacitor. In a capacitor of the present invention, the second capacitor is formed around a capacitor and the polarized condition thereof is possible to be controlled. Due to this original switching time of the first capacitor can be flexibly adjusted, and there is a significant advantage that switching characteristic of a capacitor can be greatly improved with minimum cost.
