>>3550612>>3549308That one you posted is most likely just a test wafer. Those things are practical only during the development phase when research the process and need a little bit of everything on the wafer to sample how it all turns out.
A real production wafer looks like this. There is only 1 sensor size on it.
Because this is more practical, you save the need to carefully short out the different sizesm which cuts down the sorting process which would have been necessary. These wafers have just 1 sensor size.
