Below some SEM images of amorphous TiO<sub>2</sub> deposited at 120 <sup>o</sup>C on Si trenches are shown. The width of the trenches is 200 nm, and the depth is 4 µm, i.e. the aspect ratio is 1:20. The number of cycles is 500, and this results in a TiO<sub>2</sub> layer of about 25 nm. From the SEM images it is seen that the TiO<sub>2</sub> layer covers the trenches very well. | Below some SEM images of amorphous TiO<sub>2</sub> deposited at 120 <sup>o</sup>C on Si trenches are shown.
