Your question is not clear to me.. what do you mean by "set a surface roughness tester from step height" ??

Fahad Usman

Many papers used dekak profilometer in controlling the thickness of their thin film by creating a step on the film. In my own case, I want use roughness profile from surface roughness tester (SV 3000 mitutoyo) for the thickness control. Now, I have created the step during the thin film deposition but the roughness profile is not showing any visible step. Thus, I am not sure whether the problem is from the machine settings. Thanks alot
