DEFINITION

Classification: 117/209

Including solid member shaping means other than seed or product (e.g., EDFG die):

(under subclass 208) Subject matter including a solid member (i.e., mechanical or physical shaper or die), other than the seed or the single-crystal* product, is provided sufficiently close to the precursor*-product interface to affect, and at least partially define, the shape of the crystal as it is pulled from the liquid and passes against the shaping means.

(1) Note. The solid member may be pulled with and become attached to or embedded in the crystal; e.g., string-stabilized web pulling.
