摘要:
Systems, methods, and other embodiments associated with progressive relaxation across tiers of a search system are described. One system embodiment includes a first tier of computing components that stores search data that can be used to locate documents. The system embodiment may also include a second tier of computing components that also store search data that can be used to locate documents. The system may also include a query logic that receives a query and locates a set of items relevant to the query by selectively progressively relaxing a search across the search data stored at different levels until a threshold is met.

A method for fabricating an integrated device is disclosed. A polysilicon gate electrode layer is provided on a substrate. In an embodiment, a treatment is provided on the polysilicon gate electrode layer to introduce species in the gate electrode layer and form an electrically neutralized portion therein. Then, a hard mask layer with limited thickness is applied on the treated polysilicon gate electrode layer. A tilt angle ion implantation is thus performing on the substrate after patterning the hard mask layer and the treated polysilicon gate electrode to from a gate structure.

A method for fabricating an integrated device is disclosed. The disclosed method provides improved formation selectivity of epitaxial films over a pre-determined region designed for forming an epi film and a protective layer preferred not to form an epi, polycrystalline, or amorphous film thereon during an epi film formation process. In an embodiment, the improved formation selectivity is achieved by providing a nitrogen-rich protective layer to decrease the amount of growth epi, polycrystalline, or amorphous film thereon.

An integrated circuit device and method for manufacturing the integrated circuit device is disclosed. The disclosed method provides improved control over a surface proximity and tip depth of integrated circuit device. In an embodiment, the method achieves improved control by forming a doped region and a lightly doped source and drain (LDD) region in a source and drain region of the device. The doped region is implanted with a dopant type opposite the LDD region.

A method for cleaning a diffusion barrier over a gate dielectric of a metal-gate transistor over a substrate is provided. The method includes cleaning the diffusion barrier with a first solution including at least one surfactant. The amount of the surfactant of the first solution is about a critical micelle concentration (CMC) or more. The diffusion barrier is cleaned with a second solution. The second solution has a physical force to remove particles over the diffusion barrier. The second solution is substantially free from interacting with the diffusion barrier.

A partial-via-first dual-damascene method using a tri-layer resist method forms a first via hole through partial thickness of a dielectric layer, and forms a tri-layer resist structure on the dielectric layer to fill the first via hole with the bottom photoresist layer. A dry development process is performed to transfer a first opening on the top photoresist layer to the middle layer and the bottom photoresist layer, and expose the first via hole again, and remove the top photoresist layer. A dry etching process is then performed to form a second via hole under the first via hole and a trench over the second via hole. Finally a wet striping process is used to remove the remainder of the photoresist layer.

A method is provided for fabricating a semiconductor device. The method includes removing a silicon material from a gate structure located on a substrate through a cycle including: etching the silicon material to remove a portion thereof, where the substrate is spun at a spin rate, applying a cleaning agent to the substrate, and drying the substrate; and repeating the cycle, where a subsequent cycle includes a subsequent spin rate for spinning the substrate during the etching and where the subsequent spin rate does not exceed the spin rate of the previous cycle.
