    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.

    摘要: 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.

    摘要: A method for fabricating a semiconductor device is disclosed. The method includes forming at least one material layer over a substrate; performing an end-cut patterning process to form an end-cut pattern overlying the at least one material layer; transferring the end-cut pattern to the at least one material layer; performing a line-cut patterning process after the end-cut patterning process to form a line-cut pattern overlying the at least one material layer; and transferring the line-cut pattern to the at least one material layer.

    摘要: 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.

    摘要: 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.

    摘要: 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.
