Silicon wafer thickness
- Description
- Thickness of a single wafer, measured at 9 locations for 184 consecutive batches. A single wafer is removed from a tray of wafers (always at the same position for each batch of wafers) after the chemical vapour decomposition process is complete.
- Data source
- Industrial data (origin unknown). The data have been approximately centered and scaled to disguise the original variables - for confidentiality.
The location of the 9 thicknesses are:
