    摘要: A method of forming fins for a double-gate fin field effect transistor (FinFET) includes forming a second layer of semi-conducting material over a first layer of semi-conducting material and forming double caps in the second layer of semi-conducting material. The method further includes forming spacers adjacent sides of each of the double caps and forming double fins in the first semi-conducting material beneath the double caps. The method also includes thinning the double fins to produce narrow double fins.

    摘要: A shallow trench isolation region formed in a layer of semiconductor material. The shallow trench isolation region includes a trench formed in the layer of semiconductor material, the trench being defined by sidewalls and a bottom; a liner within the trench formed from a high-K material, the liner conforming to the sidewalls and bottom of the trench; and a fill section made from isolating material, and disposed within and conforming to the high-K liner. A method of forming the shallow trench isolation region is also disclosed.

    摘要: A method for forming a fin in a semiconductor device that includes a substrate, an insulating layer formed on the substrate, and a conductive layer formed on the insulating layer, includes forming a carbon layer over the conductive layer and forming a mask over the carbon layer. The method further includes etching the mask and carbon layer to form at least one structure, where the structure has a first width, reducing the width of the carbon layer in the at least one structure to a second width, depositing an oxide layer to surround the at least one structure, removing a portion of the oxide layer and the mask, removing the carbon layer to form an opening in a remaining portion of the oxide layer for each of the at least one structure, filling the at least one opening with conductive material, and removing the remaining portion of the oxide layer and a portion of the conductive layer to form the fin.

    摘要: A double gate metal-oxide semiconductor field-effect transistor (MOSFET) includes a fin, a first gate and a second gate. The first gate is formed on top of the fin. The second gate surrounds the fin and the first gate. In another implementation, a triple gate MOSFET includes a fin, a first gate, a second gate, and a third gate. The first gate is formed on top of the fin. The second gate is formed adjacent the fin. The third gate is formed adjacent the fin and opposite the second gate.

    摘要: A device includes a fin, a first gate and a second gate. The first gate is formed adjacent a first side of the fin and includes a first layer of material having a first thickness and having an upper surface that is substantially co-planar with an upper surface of the fin. The second gate is formed adjacent a second side of the fin opposite the first side and includes a second layer of material having a second thickness and having an upper surface that is substantially co-planar with the upper surface of the fin, where the first thickness and the second thickness are substantially equal to a height of the fin.
