Zirconium nitride thin films were deposited on Si (111) substrates by balanced and unbalanced magnetron sputtering. The change in the preferred orientation of the deposited films was studied as a function of substrate bias voltage. ZrN films deposited by magnetron sputtering with out any bias voltage showed a preferred orientation of (111) where as, those deposited at higher bias voltages (above â?"60Volt) showed (200) as the preferred orientation. ZrN films deposited by unbalanced magnetron also showed a similar kind of transformation in the preferred orientation but the bias voltage required in this case was about -40V. Better quality films have been obtained with a resistivity value of 50 @micro ohm cm 1@ in unbalanced magnetron sputtering, where as, a resistivity of 63@micro ohm cm 2@ was obtained in case of magnetron sputtered ZrN thin films. The change in the surface roughness as the function of the bias voltage was also studied. @FootnoteText@ 1. @micro ohm cm 1@ 2. @micro ohm cm 2@.
