DEFINITION

Classification: 117/81

Growth confined by a solid member other than seed or product (e.g., Bridgman-Stockbarger method):

(under subclass 73) Subject matter in which a solid member, other than the seed or product, confines growth in at least one direction and at least partially defines the shape of the product; for example, a crucible* or a mold.

SEE OR SEARCH THIS CLASS, SUBCLASS:

13+, for processes of growing a single-crystal* while pulling and subclasses 16 and 23+ when the solid-liquid interface may be contacted or confined by a solid member shaping means.

43+, for processes of moving zone crystallization in which the solid-liquid interface may be confined or contacted by a solid.

54+, for processes of epitaxy*.

223, for corresponding apparatus other than coating apparatus.
