    • Methods of making fins and semiconductor structures containing fins are provided. The methods involve forming a multi-layer structure over fins and isolation materials and performing a multi-stage etching process to remove upper portions of the multi-layer structure and upper portions of isolation materials. Upper portions of the fins are exposed by removing the upper portions of the isolation materials via the multi-stage etching process. A stage of the multi-stage etching process removes an upper layer of the multi-layer structure and an upper portion of the isolation materials, and the stage can be terminated about at the same time when the upper surface of the underlying layer of the multi-layer structure is exposed.

    • Multi-gate metal oxide silicon transistors and methods of making multi-gate metal oxide silicon transistors are provided. The multi-gate metal oxide silicon transistor contains a bulk silicon substrate containing one or more convex portions between shallow trench regions; one or more dielectric portions over the convex portions; one or more silicon fins over the dielectric portions; a shallow trench isolation layer in the shallow trench isolation regions; and a gate electrode. The upper surface of the shallow trench isolation layer can be located below the upper surface of the convex portion, or the upper surface of the shallow trench isolation layer can be located between the lower surface and the upper surface of first dielectric layer. The multi-gate metal oxide silicon transistor can contain second spacers adjacent to side surfaces of the convex portions in a source/drain region.
