We investigated the microstructure of the Ti-films formed on the (001) single crystal silicon wafers through the ionized sputtering process, and compared the results with those obtained by collimated sputtering. We found that the Ti-films created by ionized sputtering process without the substrate bias show less strong (002) textures than collimated sputtering. The Ti-films created by the ionized sputtering process with the substrate bias did not show any observable strong textures. We also found that the ionized sputtering processed Ti-films show about 4 nm thick amorphous Ti-Si interlayer, which is much thicker than that of the collimated sputtering process. The modifications of the microstructure of Ti-films are attributed to the ion bombardments during the ionized sputtering deposition process.
