Titanium boride films (Ti1 - xBx: 0.5 < x < 0.77) were deposited by the co-sputtering method onto molybdenum substrates at 870 K. A negative bias voltage was applied to the substrate during deposition of the stoichiometric TiB2 by applying an r.f. power of 0-500 W to the substrates. The soft X-ray spectroscopy and other results of characterization showed that stoichiometric TiB2 could be formed by the present co-sputtering method. The application of a negative bias voltage to substrates enhanced the crystallization of TiB2 in the films. We evaluated thermal stability, deuterium retention behaviour and sputter erosion behaviour under 2 keV deuterium ion bombardment of deposited Ti1 - xBx films as functions of their chemical composition and of applied bias voltage. The paper will be focused particularly on the effects of the application of a bias voltage.
