Patent ID: 8871607

Claim:
A method for producing a hybrid substrate, including a support substrate, a continuous layer of a buried dielectric and, on the continuous layer, a hybrid layer including alternating zones of a first semi-conductor material and at least one second semi-conductor material, wherein the first semi-conductor material and the at least one second semi-conductor material are different by their nature and/or their crystallographic characteristics, the method comprising: forming the hybrid layer comprising alternating zones of the first semi-conductor material and the at least one second semi-conductor material, on or in a homogeneous substrate, the alternating zones being arranged without any insulating material between the first and at least one second semi-conductor materials; forming a fracture zone by a first implantation of ions or atoms in said hybrid layer; after the forming of the hybrid layer, intermediate assembling a free surface of the hybrid layer, or a dielectric layer formed on the free surface, with a buffer substrate; fracturing said hybrid layer along said fracture zone, thereby eliminating the homogenous substrate and a first part of said hybrid layer, leaving a second part of said hybrid layer or of said dielectric layer formed on the free surface, assembled with said buffer substrate; and second assembling the hybrid layer, the continuous layer of the buried dielectric, and the support substrate.
