DEFINITION

Classification: 117/902

SPECIFIED ORIENTATION, SHAPE, CRYSTALLOGRAPHY, OR SIZE OF SEED OR SUBSTRATE:

(under the class definition) A collection of art which specifies the orientation, shape, crystallography, or size of the seed or substrate material (e.g., lattice orientation, Miller index).

(1) Note. A complete search would include subclasses 40, 63, and 101. Cross- referencing therewith is precluded as unnecessarily duplicative.

SEE OR SEARCH THIS CLASS, SUBCLASS:

63, for processes of making single-crystals* by liquid phase epitaxy* in which the crystallos:graphic orientation of the substrate is specified.

101, for processes of making single-crystals* which includes a decomposition reaction of a precursor* (except an impurity or dopant precursor*) and further specifies the substrate* crystallography.
