DEFINITION

Fluid growth from liquid combined with preceding diverse operation:

(under subclass 478) Process having a nonfluid growth operation which precedes the fluid growth of semiconductive material from the liquid state and is not merely perfecting thereto.

(1) Note. See Class 117, class definition section I, C, (4) Note, for a detailed description of the types of perfecting prior operations which in combination with a step of single crystal growth are proper therein.
