    Abstract: A self-aligned conductive spacer process for fabricating sidewall control gates on both sides of a floating gate for high-speed RAM applications, which can well define dimensions and profiles of the sidewall control gates. A conductive layer is formed on the dielectric layer to cover a floating gate patterned on a semiconductor substrate. Oxide spacer are formed on the conductive layer adjacent to the sidewalls of the floating gate. Performing an anisotropic etch process on the conductive layer and using the oxide spacers as a hard mask, a conductive spacers are self-aligned fabricated at both sides of the floating gate, serving as sidewall control gates.

    Abstract: A semiconductor device and method of fabricating thereof is described that includes a substrate having a fin with a top surface and a first and second lateral sidewall. A hard mask layer may be formed on the top surface of the fin (e.g., providing a dual-gate device). A gate dielectric layer and work function metal layer are formed on the first and second lateral sidewalls of the fin. A silicide layer is formed on the work function metal layer on the first and the second lateral sidewalls of the fin. The silicide layer may be a fully-silicided layer and may provide a stress to the channel region of the device disposed in the fin.
