This section assumes that the Recipe Creation and Signals Processing sections have already been reviewed and followed. A recipe has been created for the film stack, the signal is optimized to the substrate, and the spectrum is in Reflectance Mode.
Click Load Recipe.
Choose the appropriate recipe for your material. Click Open to load the recipe.
Physically switch from the substrate/reference sample to the coated sample to be tested and click Measure Thickness in the Data Table.
There are dropdown options to perform either Reflectance or Transmittance measurement and another dropdown options to display the calculated results in Nanometer or Angstroms.
The software will collect the next scan from the spectrometer, calculate the film thickness for each layer, calculate the r^2 value for the calculation, and display both the model simulated material and real data collected from the spectrometer overlayed on the graph. The white trace is the data collected from the spectrometer and the green trace is the modeled data.
Example Calculations:
Next, data can be saved by clicking on the Save icon.
Choose a location, name the sample, and then click “Save” to save the data to the file system.
The File>Save will create 3 files.
A PDF test report with the user account name, time-stamp, and calculated values.
The raw Scope Mode data in ASCII formatted space delimited text.
The Transmission/Reflectance Mode data in ASCII formatted space delimited text.
