Abstract

Polycrystalline Ba_0.4 Sr_0.6 TiO₃ (BST) thin films grown at 350°C with UV-assisted rapidly thermal annealing (RTA) showed a high- k value of 183 at 100 kHz. The 100 nm thick BST film with UV-assisted RTA exhibited a high capacitance density of 16.2 fF/μ m ² and a low dissipation factor of 0.48% at 100 kHz with a low leakage current density of 1× 10-8 A/ cm² at 0.5 MV/cm. The quadratic and linear voltage coefficients of capacitances of the BST film with UV-assisted RTA were -155 ppm/ V² and 231 ppm/V, respectively. All these make the BST decoupling capacitor very suitable for use in radio-frequency circuits and mixed-signal integrated circuits.
