To callibrate the sputterer FTM coat to a nominal thickness then pass the sample to Rod Dykeman who'll scratch the coating and measure it using a Tallystep.

If the coating is too hard (eg ITO) then you'll have to mask out some areas using photoresist and lift off to provide an edge. This might be possible using some dabs of photoresist rather than a spincoated layer and mask exposure.
