Example 1: The surface roughness (Ra) of a metallic film on a silicon wafer is 0.004 μm
In the upper left image, the height is color-coded. The Ra surface roughness value along the horizontal line shown is 0.003 μm, with the height along that line shown in the lower left image. The Ra surface roughness in the entire 0.09mm x 0.06mm area examined is 0.004 μm. The 3-dimensional plot of the image in the upper right displays the sample height directly.
Example 2: The surface roughness (Ra) of a metallic film on a silicon wafer is 0.011 μm
Example 3: The surface roughness (Ra) of a metallic film on a silicon wafer is 0.077 μm
