摘要:
A multi-layered gate electrode stack structure of a field effect transistor device is formed on a silicon nano crystal seed layer on the gate dielectric. The small grain size of the silicon nano crystal layer allows for deposition of a uniform and continuous layer of poly-SiGe with a [Ge] of up to at least 70% using in situ rapid thermal chemical vapor deposition (RTCVD). An in-situ purge of the deposition chamber in a oxygen ambient at rapidly reduced temperatures results in a thin SiO2 or SixGeyOz interfacial layer of 3 to 4A thick. The thin SiO2 or SixGeyOz interfacial layer is sufficiently thin and discontinuous to offer little resistance to gate current flow yet has sufficient [O] to effectively block upward Ge diffusion during heat treatment to thereby allow silicidation of the subsequently deposited layer of cobalt. The gate electrode stack structure is used for both nFETs and pFETs.

摘要:
A method and structure for a method of manufacturing a device having different types of transistors, wherein gates of the different types of transistors in the device comprise different materials. The method comprises depositing a silicon layer on a gate dielectric layer, depositing a first-type gate material on the silicon layer, removing the first-type gate material from areas where a second-type gate is to be formed, depositing a second-type gate material on the silicon layer in areas where the first-type gate material was removed, and simultaneously patterning the first-type gate material and the second-type gate material into first-type and second-type gates, and anneal and transform the two types of gate materials.

A method of establishing personalized limits on a search responsive to a key word query in an enterprise search system is described that includes receiving an object types access history for a particular user. Applying this method, the object types access history includes records of object types selected from search results returning multiple object types and records of object types selected via interfaces other than search results. The method continues with determining and storing in computer readable memory a personalized scope of object types. The personalized scope of object types sets a limit on object types initially returned by an enterprise search system for the particular user in response to key word queries by the particular user that do not specify object types to search.

摘要:
A method that solves the increased nucleation temperature that is exhibited during the formation of cobalt disilicides in the presence of Ge atoms is provided. The reduction in silicide formation temperature is achieved by first providing a structure including a Co layer including at least Ni, as an additive element, on top of a SiGe containing substrate. Next, the structure is subjected to a self-aligned silicide process which includes a first anneal, a selective etching step and a second anneal to form a solid solution of (Co, Ni) disilicide on the SiGe containing substrate. The Co layer including at least Ni can comprise an alloy layer of Co and Ni, a stack of Ni/Co or a stack of Co/Ni. A semiconductor structure including the solid solution of (Co, Ni) disilicide on the SiGe containing substrate is also provided.
