  • Patent number: 12159803
    Abstract: In some embodiments, the present disclosure relates to a method that includes forming a shallow trench isolation (STI) structure that extends into a substrate. A masking layer is formed over the substrate and includes an opening overlying the STI structure. A first removal process removes portions of the STI structure underlying the opening of the STI structure. A second removal process laterally removes portions of the substrate below the STI structure. A third removal process removes portions of the substrate that directly underlie the opening of the masking layer. An insulator liner layer is formed within inner surfaces of the substrate as defined by the first, second, and third removal processes. Further, a fourth removal process removes portions of the insulator liner layer covering a lower surface of the substrate. A semiconductor material is then formed over the SOI substrate and on the insulator liner layer.
