Hi Mike;
Big thanks for getting back to us. Here is what I see when I do the following.
1. Start the Semiconductor Toolkit Add In.
2. Click the Bare Wafer Map (Mapping) button.
3. Click OK to load the example data set.
4. Configure the plot for Response to Response axis, XY to XY Coordinates, and Sampling pattern to By. Five square maps are displayed.
5. Right-click on the displayed "49 site Radial" map and select Graph --> Background Map.
Attached is what is displayed. Note that I have already placed "300mm_wafer" in the list of Unsorted Background Maps.
