1. A method for slicing an ingot having a surface curvature into a plurality of wafers via a slurry while the slurry is supplied
to a moving wire, the method comprising:
slicing a first guide beam having a surface curvature substantially the same as the ingot surface curvature attached to one
side of the ingot, with the moving wire;
slicing the ingot; and
slicing a second guide beam having a surface curvature substantially the same as the ingot surface curvature attached to an
other side opposite to the one side of the ingot.
