  • Publication number: 20050215040
    Abstract: The present invention relates to a method of forming a quantum wire gate device. The method includes patterning a first oxide upon a substrate. Preferably the first oxide pattern is precisely and uniformly spaced to maximize quantum wire numbers per unit area. The method continues by forming a first nitride spacer mask upon the first oxide and by forming a first oxide spacer mask upon the first nitride spacer mask. Thereafter, the method continues by forming a second nitride spacer mask upon the first oxide spacer mask and by forming a plurality of channels in the substrate that are aligned to the second nitride spacer mask. A dielectric is formed upon the channel length and the method continues by forming a gate layer over the plurality of channels. Because of the inventive method and the starting scale, each of the plurality of channels is narrower than the mean free path of semiconductive electron flow therein.

  • Publication number: 20050158970
    Abstract: Embodiments of the invention provide a method for effecting uniform silicon body height for silicon-on-insulator transistor fabrication. For one embodiment, a sacrificial oxide layer is disposed upon a semiconductor substrate. The oxide layer is etched to form a trench. The trench is then filled with a semiconductor material. The semiconductor material is then planarized with the remainder of the oxide layer and the remainder of the oxide layer is then removed. The semiconductor fins thus exposed are of uniform height to within a specified tolerance.

  • Patent number: 6794232
    Abstract: Insulated gate field effect transistors having gate electrodes with at least two layers of materials provide gate electrode work function values that are similar to those of doped polysilicon, eliminate the poly depletion effect and also substantially prevent impurity diffusion into the gate dielectric. Bi-layer stacks of relatively thick Al and thin TiN for n-channel FETs and bi-layer stacks of relatively thick Pd and thin TiN, or relatively thick Pd and thin TaN for p-channel FETs are disclosed. Varying the thickness of the thin TiN or TaN layers between a first and second critical thickness may be used to modulate the work function of the gate electrode and thereby obtain the desired trade-off between channel doping and drive currents in FETs.
