    Abstract: Methods and structures for fabricating fins for multigate devices are disclosed. In accordance with one method, a plurality of sidewalls are formed in or on a plurality of mandrels over a semiconductor substrate such that each of the mandrels includes a first sidewall composed of a first material and a second sidewall composed of a second material that is different from the first material. The first sidewall of a first mandrel of the plurality of mandrels is selectively removed. In addition, a pattern composed of remaining sidewalls of the plurality of sidewalls is transferred onto an underlying layer to form a hard mask in the underlying layer. Further, the fins are formed by employing the hard mask and etching semiconducting material in the substrate.

    Abstract: A transistor device and a method for forming a fin-shaped field effect transistor (FinFET) device, with the channel portion of the fins on buried silicon oxide, while the source and drain portions of the fins on silicon. An example method includes receiving a wafer with a silicon layer electrically isolated from a silicon substrate by a buried oxide (BOX) layer. The BOX layer is in physical contact with the silicon layer and the silicon substrate. The method further comprises implanting a well in the silicon substrate and forming vertical sources and drains over the well between dummy gates. The vertical sources and drains extend through the BOX layer, fins, and a portion of the dummy gates.

    Abstract: A semiconductor device comprises an insulation layer, an active semiconductor layer formed on an upper surface of the insulation layer, and a plurality of fins formed on the insulation layer. The fins are formed in the gate and spacer regions between a first source/drain region and second source/drain region, without extending into the first and second source/drain regions.

    Abstract: A method for semiconductor fabrication includes patterning one or more mandrels over a semiconductor substrate, the one or more mandrels having dielectric material formed therebetween. A semiconductor layer is formed over exposed portions of the one or more mandrels. A thermal oxidation is performed to diffuse elements from the semiconductor layer into an upper portion of the one or more mandrels and concurrently oxidize a lower portion of the one or more mandrels to form the one or more mandrels on the dielectric material.
