  • Patent number: 10510583
    Abstract: The disclosed method is suitable for producing a SiGe-on-insulator structure. According to some embodiments of the method, a layer comprising SiGe is deposited on silicon-on-insulator substrate comprising an ultra-thin silicon top layer. In some embodiments, the layer comprising SiGe is deposited by epitaxial deposition. In some embodiments, the SiGe epitaxial layer is high quality since it is produced by engineering the strain relaxation at the Si/buried oxide interface. In some embodiments, the method accomplishes elastic strain relaxation of SiGe grown on a few monolayer thick Si layer that is weakly bonded to the underline oxide.
