DEFINITION

Classification: 117/43

Distinctly layered product (e.g., twin, SOI, epitaxial crystallization):

(under subclass 37) Subject matter in which the process results in a product having distinct layers.

(1) Note. All the layers need not be single-crystal*, nor do they need to be formed by the process.

(2) Note. A layer may be a seed* or merely a confining or contacting member.
