DEFINITION

Classification: 117/30

With liquid flow control or manipulation during growth (e.g., mixing, replenishing, magnetic levitation, stabilization, convection control, baffle):

(under subclass 13) Subject matter wherein flow of a liquid precursor* is purposefully manipulated or controlled during growth.

SEE OR SEARCH THIS CLASS, SUBCLASS:

15+, if the control is in response to a measured, tested, or sensed condition or parameter.

33, for processes wherein the manipulation or control comprises replenishing of the liquid precursor*.
