Abstract: Two different transistors types are made on different crystal orientations in which both are formed on SOI. A substrate has an underlying semiconductor layer of one of the crystal orientations and an overlying layer of the other crystal orientation. The underlying layer has a portion exposed on which is epitaxially grown an oxygen-doped semiconductor layer that maintains the crystalline structure of the underlying semiconductor layer. A semiconductor layer is then epitaxially grown on the oxygen-doped semiconductor layer. An oxidation step at elevated temperatures causes the oxide-doped region to separate into oxide and semiconductor regions. The oxide region is then used as an insulation layer in an SOI structure and the overlying semiconductor layer that is left is of the same crystal orientation as the underlying semiconductor layer. Transistors of the different types are formed on the different resulting crystal orientations.

Nanotubes from each column of metallic catalyst are laterally grown and either abut or merge into one nanotube. Contact to the nanotube may be made from either the neck portion or the columns of metallic catalysts.

Abstract: A semiconductor device having a gate with a thin conductive layer is described. As the physical dimensions of semiconductor devices are scaled below the sub-micron regime, very thin gate dielectrics are used. One problem encountered with very thin gate dielectrics is that the carriers can tunnel through the gate dielectric material, thus increasing the undesirable leakage current in the device. By using a thin layer for conductive layer, quantum confinement of carriers within conductive layer can be induced. This quantum confinement removes modes which are propagating in the direction normal to the interfacial plane from the Fermi level. Thus, the undesirable leakage current in the device can be reduced. Additional conductive layers may be used to provide more carriers.
