Abstract

Ti films were deposited onto 100${\times}$100 mm alumina substrates using dc magnetron sputtering under the following conditions; substrate temperature of R.T～400 $^{\circ}C$, annealing temperature of 100～400 $^{\circ}C$, and sputtering gas pressure of 4${\times}$10$^{-3}$ Torr～4${\times}$10$^{-2}$ Torr. And the films were examined by X-ray diffraction analysis (XRD), scanning electron microscopy(SEM) and 4-point measurement system. The best electrical and structural properties was obtained by substrate temperature of ～200 $^{\circ}C$, target-substrate distance of ～14 cm and sputtering pressure of ～1${\times}$10$^{-2}$ Torr. Also at that condition the most excellent adhesion was observed.
