Abstract:
1. Method for manufacturing an SOI substrate associating at least one silicon based area ( 4 ′) and at least one GaAs based material area ( 8 ) at the thin layer ( 1 ) of the SOI substrate, the SOI substrate comprising a support ( 2 ) having a silicon face supporting successively a layer ( 3 ) of dielectric material and a thin silicon based layer ( 4 ), the method being characterised in that it comprises the following steps: supply of a SOI substrate ( preservation of at least one area ( elimination of at least one non-preserved area of the thin layer of silicon until the layer ( opening, in said non-preserved area, of the dielectric material layer ( growth, from the silicon of the support ( growth of the GaAs based material (
