    摘要: The invention relates to a method for fabricating a composite structure having heat dissipation properties greater than a bulk single crystal silicon structure having the same dimensions, the structure comprising a support substrate, a top layer and an oxide layer between the support substrate and the top layer, the method comprising the steps of: a) providing a top layer made of a crystalline material, b) bonding the top layer with a support substrate made of a polycrystalline material having high heat dissipation properties, such that an oxide layer is formed at the bonding interface, in order to obtain said structure, characterized in that it further comprises a heat treatment of the structure in an inert or reducing atmosphere at a predetermined temperature and a predetermined duration to increase the heat dissipation properties by dissolving at least a part of the oxide layer.

    摘要: The invention concerns a method for transferring an electrically active thin layer from an initial substrate onto a target substrate, comprising the following steps: ion implantation through one surface of the initial substrate to produce an embrittled embedded layer at a specific depth relative to the implanted surface of the initial substrate, a thin layer being thereby delimited between the implanted surface and the embedded layer; securing the implanted side of the initial substrate on a surface of the target substrate; separating the thin layer from the rest of the initial substrate at the embedded layer; thinning down the thin layer transferred onto the target substrate. The dose, energy and current of the implantation are selected, during the ion implantation step, such that the defect concentration of the implantation is less than a specific threshold which results in obtaining in the thin layer the desired electrical properties for the thin layer.
