    Abstract: The introduction of a barrier diffusion material, such as nitrogen, into a silicon-containing conductive region, for example the drain and source regions (204, 205) and the gate electrode (208) of a field effect transistor, allows the formation of nickel silicide (211, 212), which is substantially thermally stable up to temperatures of 500 °C. Thus, the device performance may significantly improve as the sheet resistance of nickel silicide is significantly less than that of nickel disilicide.

    Abstract: A method of forming oxide layers of different thickness on a substrate (1) is disclosed, wherein the oxide layers preferably serve as gate insulation layers of field effect transistors. The method allows to form very thin, high quality oxide layers with a reduced number of masking steps compared to the conventional processing, wherein the thickness difference can be maintained within a range of some tenths of a nanometer. The method substantially eliminates any high temperature oxidations and is also compatible with most chemical vapor deposition techniques used for gate dielectric deposition in sophisticated semiconductor devices

    Abstract: The present invention provides a technique for forming extremely thin insulation layers requiring the incorporation of specified amounts of nitrogen, wherein the effect of nitrogen variations across the substrate surface may be reduced in that during and/or after the nitrogen incorporation an oxidation process is performed. The nitrogen variations lead to a nitrogen concentration dependent oxidation rate and, hence, a nitrogen concentration dependent thickness variation of the insulating layer. In particular, the threshold variations of transistors including the thin insulating layer as a gate insulation layer may effectively be reduced.

    Abstract: A semiconductor device comprises a field effect transistor (250) and a passive capacitor (240), wherein the dielectric layer (221a) of the capacitor (240) is comprised of a high-k material, whereas the gate insulation layer (231) of the field effect transistor (250) is formed of an ultra thin oxide layer or oxynitride layer so as to provide for superior carrier mobility at the interface between the gate insulation layer and the underlying channel region. Since carrier mobility in the capacitor is not of great importance, the high-k material allows the provision of high capacitance per unit area while featuring a thickness sufficient to effectively reduce leakage current.
