Claim:
1. A method useful for orienting the crystallization of a material over a surface zone of at least one face of a substrate, comprising at least the steps consisting in: (i) determining, on said face, the surface over which the crystalline deposit must be formed, referred to as the zone of interest; (ii) depositing, on said face and at the periphery of said zone of interest, at least one particle dedicated to forming a crystallization nucleus; (iii) bringing said particle into contact with at least said material to be crystallized; and (iv) exposing at least said point of contact between said particle and said material to be crystallized to conditions favorable to the crystallization of said material; the surface of said particle being partly functionalized with at least one group having an affinity for said material to be crystallized, said group possessing at least one unit having a chemical nature identical to at least one part of the chemical structure of said material to be crystallized, and in that said particle is deposited in step (ii) so as to expose said group opposite the zone to be crystallized.
