A method for organizing deep Web services is provided. In one aspect, the method obtains a collection of sources and their associated attributes and/or input modes, for instance, using a crawling algorithm. The method uses this information to organize the sources into communities. A mining algorithm such as the hyperclique mining algorithm is used to obtain cliques of highly correlated attributes. A clustering algorithm such as the hierarchical agglomerative clustering algorithm is used to further cluster the cliques of attributes into larger cliques, which in the present disclosure is referred to as signatures. The sources that are associated with each signature form a community and a graph representation of the communities is constructed, where the vertices are communities and the edges are the shared attributes.

In one embodiment, a method of forming a semiconductor device is provided that includes providing a gate structure on a semiconductor substrate. Sidewall spacers may be formed adjacent to the gate structure. A metal semiconductor alloy may be formed on the upper surface of the gate structure and on an exposed surface of the semiconductor substrate that is adjacent to the gate structure. An upper surface of the metal semiconductor alloy is converted to an oxygen-containing protective layer. The sidewall spacers are removed using an etch that is selective to the oxygen-containing protective layer. A strain-inducing layer is formed over the gate structure and the semiconductor surface, in which at least a portion of the strain-inducing layer is in direct contact with the sidewall surface of the gate structure. In another embodiment, the oxygen-containing protective layer of the metal semiconductor alloy is provided by a two stage annealing process.

A method of fabricating a Schottky field effect transistor is provided that includes providing a substrate having at least a first semiconductor layer overlying a dielectric layer, wherein the first semiconductor layer has a thickness of less than 10. 0 nm. A gate structure is formed directly on the first semiconductor layer. A raised semiconductor material is selectively formed on the first semiconductor layer adjacent to the gate structure. The raised semiconductor material is converted into Schottky source and drain regions composed of a metal semiconductor alloy. A non-reacted semiconductor material is present between the Schottky source and drain regions and the dielectric layer.

Electronic devices having carbon-based materials and techniques for making contact to carbon-based materials in electronic devices are provided. In one aspect, a device is provided having a carbon-based material; and at least one electrical contact to the carbon-based material comprising a metal silicide, germanide or germanosilicide. The carbon-based material can include graphene or carbon nano-tubes. The device can further include a segregation region, having an impurity, separating the carbon-based material from the metal silicide, germanide or germanosilicide, wherein the impurity has a work function that is different from a work function of the metal silicide, germanide or germanosilicide. A method for fabricating the device is also provided.

Techniques for silicide, germanide or germanosilicide formation in extremely small structures are provided. In one aspect, a method for forming a silicide, germanide or germanosilicide in a three-dimensional silicon, germanium or silicon germanium structure having extremely small dimensions is provided. The method includes the following steps. At least one element is implanted into the structure. At least one metal is deposited onto the structure. The structure is annealed to intersperse the metal within the silicon, germanium or silicon germanium to form the silicide, germanide or germanosilicide wherein the implanted element serves to prevent morphological degradation of the silicide, germanide or germanosilicide. The implanted element can include at least one of carbon, fluorine and silicon.

An epitaxial Ni silicide film that is substantially non-agglomerated at high temperatures, and a method for forming the epitaxial Ni silicide film, is provided. The Ni silicide film of the present disclosure is especially useful in the formation of ETSOI (extremely thin silicon-on-insulator) Schottky junction source/drain FETs. The resulting epitaxial Ni silicide film exhibits improved thermal stability and does not agglomerate at high temperatures.
