2-4.Wafer Surface Orientation

2-4.Wafer Surface Orientation

Denotes the orientation of the surface of a wafer with respect to a crystallographic plane within the lattice structure.
In wafers cut intentionally “off orientation”, the direction of cut is parallel to the primary  at, away from the secondary  at.
Measured with x-ray goniometer on a sample of one wafer per ingot in the center of the wafer.
