  • Patent number: 12068206
    Abstract: Embodiments of the present disclosure are based on extending a nanocomb transistor architecture to implement gate all around, meaning that a gate enclosure of at least a gate dielectric material, or both a gate dielectric material and a gate electrode material, is provided on all sides of each nanoribbon of a vertical stack of lateral nanoribbons of a nanocomb transistor arrangement. In particular, extension of a nanocomb transistor architecture to implement gate all around, proposed herein, involves use of two dielectric wall materials which are etch-selective with respect to one another, instead of using only a single dielectric wall material used to implement conventional nanocomb transistor arrangements. Nanocomb-based transistor arrangements implementing gate all around as described herein may provide improvements in terms of the short-channel effects of conventional nanocomb transistor arrangements.
