Abstract: A method and system for tunable removal rates and selectivity of materials during chemical-mechanical polishing using a chemical slurry or solution with increased dissolved oxygen content. The slurry can optionally include additives to improve removal rate and/or selectivity. Further selectivity can be obtained by varying the concentration and type of abrasives in the slurry, using lower operating pressure, using different pads, or using other additives in the dispersion at specific pH values.

Abstract: Method for attaching one or more tables online to a range partitioned table, includes: starting a child transaction; obtaining an exclusive lock on a source table; obtaining an intent exclusive lock on a target table; soft invalidating queries on the target table where compiled form of queries are cached for reuse; attaching the source table(s) to the target table as a new partition(s) of the target table; modifying indices and table structure of the target table to reflect the attaching of the new partition; committing the child transaction; and releasing the exclusive lock and the intent exclusive lock, where concurrently running queries over the target table continue to run without considering the partition until the intent exclusive lock and the exclusive lock are released. Queries on the target table only consider existing partitions when the attaching is in progress. The new partition is available once the attach operation is complete.

Abstract: A method for offloaded handling of metadata storage management in a utility file system includes trapping a request for a file operation from an application process directed to a specified file of metadata stored in a utility file system of a host data processing system. The method further includes determining whether the application process is part of a privileged application or an unprivileged application and restricting access to the specified file if it is determined that the application process is part of an unprivileged application, but otherwise transforming the specified request into at least one predetermined operation if it is determined that the application process is part of a privileged application and directing the performance of the predetermined operation in the utility file system.

Abstract: A chemical mechanical planarization method uses a chemical mechanical planarization composition that includes at least one nitrogen containing material and a pH modifying material, absent an abrasive material. The nitrogen containing material may be selected from a particular group of nitrogen containing polymers and corresponding nitrogen containing monomers. The chemical mechanical planarization method and the chemical mechanical planarization composition provide for planarizing a silicon material layer, such as but not limited to a poly-Si layer, in the presence of a silicon containing dielectric material layer, such as but not limited to a silicon oxide layer or a silicon nitride layer, with enhanced efficiency provided by an enhanced removal rate ratio.

Abstract: A method, computer program product, and system for providing access to a database object during modification of that object. Upon receipt of a data definition language (DDL) operation specifying a modification to the database object, currently executing database transactions are invalidated in a two-step process of a soft invalidation followed by a hard invalidation. The soft invalidation permits the current database transactions to continue executing while modifying the logical structure of the database object in accordance with the DDL operation, and the hard invalidation waits for the database transactions started prior to the DDL operation to finish execution before modifying the physical structure of the database object in accordance with the DDL operation. After the modification to the logical structure is complete, new database transactions are allowed to execute against the modified database object, thus improving the availability of the object while it is being modified.

Abstract: In some embodiments, a computer-aided design system comprises a functional regularity extraction component, a structural regularity extraction component and a floorplanning component. The structural regularity extraction component provides a method to extract regularity for circuits (and in particular datapath circuits) based on the structural characteristics of a logic design. Some embodiments of the structural regularity extraction component automatically generate a set of vectors for the logic design. A vector is a group of template instances that are identical in function and in structure. The vectors generated by the structural regularity extraction component are used by a floorplanning component. The floorplanning component provides a method of generating a circuit layout from the set of vectors. In some embodiments, each vectors corresponds to a row in the circuit layout.
