DEFINITION

Classification: 117/49

Liquid zone contacts only precursor and product solids (e.g., crucibleless, liquid encapsulant, float zone):

(under subclass 37) Subject matter in which the liquid region is characterized by being free of direct contact with any solid (e.g., the wall of a crucible* or the surface of a substrate) other than the precursor* and the single-crystal* product.
