ABSTRACT:
It is an object of the present invention to provide an apparatus and a method for manufacturing a wafer, which are the most suitable for meeting the requirement for the mirror grinding surface of the wafer's chamfering portion. As a result, when the ingot is sliced, a wafer being sliced is chamfered at the same time. And, it is also possible that before the ingot starts to be sliced by the blade, the grindstone is pressed against the outer periphery of the slicing position to form a V-shaped groove along the outer periphery of the slicing position, so that the chamfering can be performed.
