    摘要: A method for creating insulated gate field effect transistors having gate electrodes with at least two layers of materials to provide gate electrode work function values that are similar to those of doped polysilicon, to eliminate the poly depletion effect, and to substantially prevent impurity diffusion into the gate dielectric. Depositing 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 is 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.

    摘要: A method for electrically coupling a first set of electrically conductive pads on a first semiconductor substrate to a second set of electrically conductive pads on a second semiconductor substrate is described. Dielectric material of a first thickness is deposited on at least one set of the first and second sets of electrically conductive pads. The first and second semiconductor substrates are then attached together such that such that the first and second sets of pads are substantially aligned parallel to one another and such that the dielectric material is disposed between the first and second sets of electrically conductive pads.

    摘要: A process of producing controllable thicknesses of silicon-on-insulator (SOI) for fully-depleted double-gate applications is provided. The process comprises depositing an oxide layer on a silicon wafer, depositing a nitride layer of a controlled thickness on the oxide layer, etching the nitride layer to open a first trench of controlled thickness, opening a second trench down to the silicon substrate, growing epitaxial silicon using epitaxial lateral overgrowth (ELO) to fill the second trench and grow sideways to fill the first trench, perform planarization of ELO silicon using the nitride layer as a chemical-mechanical polishing (CMP) stop layer, and fabricating a SOI device in the first trench.
