    摘要: A method is provided for fabricating a gate structure for a semiconductor device in which the gate structure has an inner spacer. A replacement-gate process is used in which material is removed in a gate region to expose a portion of the substrate; a gate dielectric is formed on the exposed portion of the substrate; and an inner spacer layer is formed overlying the gate dielectric and the dielectric material. A silicon layer is then formed which overlies the inner spacer layer. The structure is then planarized so that portions of the silicon layer and inner spacer layer remain in the gate region. A silicide gate structure is then formed from the silicon; the silicide gate structure is separated from dielectric material surrounding the gate by the inner spacer layer. The semiconductor device may include a first gate region and a second gate region with an interface therebetween, with the inner spacer layer covering the interface. When the device has two gate regions, the process may be used in both gate regions, so as to produce separate silicide structures, with an inner spacer separating the two structures.

    摘要: Semiconductor structures, such as, for example, field effect transistors (FETs) and/or metal-oxide-semiconductor capacitor (MOSCAPs), are provided in which the workfunction of a conductive electrode stack is changed by introducing metal impurities into a metal-containing material layer which, together with a conductive electrode, is present in the electrode stack. The choice of metal impurities depends on whether the electrode is to have an n-type workfunction or a p-type workfunction. The present invention also provides a method of fabricating such semiconductor structures. The introduction of metal impurities can be achieved by codeposition of a layer containing both a metal-containing material and workfunction altering metal impurities, forming a stack in which a layer of metal impurities is present between layers of a metal-containing material, or by forming a material layer including the metal impurities above and/or below a metal-containing material and then heating the structure so that the metal impurities are introduced into the metal-containing material.

    摘要: A method for forming a TiN layer on top of a metal silicide layer in a semiconductor structure without the formation of a thick amorphous layer containing Ti, Co and Si and the structure formed are provided. In the method, after a Ti layer is deposited on top of a metal silidide layer, a dual-step annealing process is conducted in which a low temperature annealing in a forming gas (or ammonia) at a temperature not higher than 500° C. is first conducted for less than 2 hours followed by a high temperature annealing in a nitrogen-containing gas (or ammonia) at a second temperature not lower than 500° for less than 2 hours to form the TiN layer. The present invention method prevents the problem usually caused by a thick amorphous material layer of Ti—Si—Co which produces weakly bonded Ti which reacts with fluorine atoms from WF6 during a subsequent CVD W deposition process and causes liner failure due to a volume expansion of the amorphous material. The maximum thickness of the amorphous material layer formed by the present invention method is less than 5 nm which minimizes the line failure problem.
