What are Silicon Wafer Flats?

PAM XIAMEN offers Silicon Wafer Flats

Since Silicon Wafers look basically the same! Flats are cut into the edge of the wafers so users could determine the wafer’s dopant-type and orientation.

 

 

 

 

Below is an example of silicon wafers flat specs:

Spec. 2” 3” 100mm 125mm 150mm 200mm 300mm

But flats are not a universal standard. You can order any silicon ingot and have the plant cut any type of flat out of the wafer. So P/Boron (100) Silicon Wafers may have just one flat.
