    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 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 method of manufacturing a semiconductor device may include forming a fin structure on an insulator. The fin structure may include side surfaces and a top surface. The method may also include depositing a gate material over the fin structure and planarizing the deposited gate material. An antireflective coating may be deposited on the planarized gate material, and a gate structure may be formed out of the planarized gate material using the antireflective coating.

    摘要: A method of using carbon spacers for critical dimension reduction can include providing a patterned photoresist layer above a substrate where the patterned photoresist layer has an aperture with a first width, depositing a carbon film over the photoresist layer and etching the deposited carbon film to form spacers on lateral side walls of the aperture of the patterned photoresist layer, etching the substrate using the formed spacers and patterned photoresist layer as a pattern to form a trench having a second width, and removing the patterned photoresist layer and formed spacers using an oxidizing etch.
