Abstract
The structural properties of strontium titanate films and the electrical parameters of the related capacitor structures have been investigated. It has been found that the deposition temperature exerts a direct effect on the phase composition of the films, the degree of perfection of the crystal structure, and the internal stresses in the lattice. The strontium titanate films deposited at a temperature of 800°C are single-phase, have a rather perfect crystal structure, and possess minimum internal stresses. It has been shown that the capacitor structures based on oriented strontium titanate films provide a twofold decrease in the level of dielectric loss as compared to similar structures based on barium strontium titanate solid solution films at a frequency of 1.5 GHz.
