A manufacturer of semiconductors wants to inspect dies on semiconductor wafers from 5 different lots. They give each die a X and Y coordinate, then they inspect the number of defects on each die.
You can use this data to demonstrate Wafer Plot.
| Worksheet column | Description | 
|---|---|
| Lot | The lot number of the semiconductor. | 
| X | The X coordinate of the semiconductor. | 
| Y | The Y coordinate of the semiconductor. | 
| Defects | The number of defects on the semiconductor. |
