COMPOSITE STRUCTURE WITH UNIFORM CRYSTALLINE ORIENTATION AND METHOD FOR CONTROLLING THE CRYSTALLINE ORIENTATION OF SUCH A STRUCTURE

摘要

The invention relates to a method of controlling the orientation of secondary structures (A1, A2) with at least one crystal part during the transfer of secondary structures from a primary structure (A), on which the secondary structures have an identical initial crystal orientation, to at least one support structure (B). Said method comprises the following steps: a) when the secondary structures are solidly connected to the primary structure (A), the formation of at least one orientation reference mark (Va, Va1, Va2), said reference mark having an arbitrary orientation in relation to said initial crystal orientation but identical for each secondary structure; and b) during the transfer of a set of secondary structures on the support structure (B), the arranging of secondary structures in such a way as to orient the orientation reference marks thereof uniformly.
