    Abstract: A method of forming self-aligned STI regions extending over portions of a Si substrate to enable the subsequent formation of epitaxially grown embedded S/D regions without using a lithography mask and the resulting device are provided. Embodiments include forming a STI etch mask with laterally separated openings over a Si substrate; forming shallow trenches into the Si substrate through the openings; forming first through fourth oxide spacers on opposite sidewalls of the shallow trenches and the openings; forming a deep STI trench between the first and second oxide spacers and between the third and fourth oxide spacers down into the Si substrate; forming a STI oxide layer over the first through fourth oxide spacers and a portion of the STI etch mask, the STI oxide layer filling the deep STI trenches; and planarizing the STI oxide layer down to the portion of the STI etch mask.

    Abstract: Methods are presented for facilitating fabrication of a semiconductor device, such as a gate-all-around nanowire field-effect transistor. The methods include, for instance: providing at least one stack structure including at least one layer or bump extending above the substrate structure; selectively oxidizing at least a portion of the at least one stack structure to form at least one nanowire extending within the stack structure(s) surrounded by oxidized material of the stack structure(s); and removing the oxidized material from the stack structure(s), exposing the nanowire(s). This selectively oxidizing may include oxidizing an upper portion of the substrate structure, such as an upper portion of one or more fins supporting the stack structure(s) to facilitate full 360° exposure of the nanowire(s). In one embodiment, the stack structure includes one or more diamond-shaped bumps or ridges.
