Barrier first method for single damascene trench applications

Methods for forming a diffusion barrier on low aspect features of an integrated circuit include at least three operations. The first operation deposits a barrier material and simultaneously etches a portion of an underlying metal at the bottoms of recessed features of the integrated circuit. The second operation deposits barrier material to provide some minimal coverage over the bottoms of the recessed features. The third operation deposits a metal conductive layer. Controlled etching is used to selectively remove barrier material from the bottom of the recessed features, either completely or partially, thus reducing the resistance of subsequently formed metal interconnects.

The invention relates to a multitask concurrent executive system and a method for hybrid network service. The system comprises a client side, a load-balancing server, a signalling / media control server and an application server cluster. The running method thereof is as follows: after the client side receives a service request, the load-balancing server selects an optimum application server and transmits the service request to a service bus thereof. After an admission control module of the application server carries out admission control on the request, the service bus transmits the request to a dynamic flow execution engine, the dynamic flow execution engine starts a service flow corresponding to the request to analyze and process, and the service bus calls a corresponding service capability component in a low deferred event service engine and interacts with the signalling / media control server through the resource adapter so as to call the service resource of the latter; and a processing result is returned to the client side according to a reverse process. The multitask concurrent executive system supports the supply of hybrid network service over a telecommunication network and the internet and the multitask concurrent on a heterogeneous network and terminals.

Radio resource allocation mechanism

A cellular communication system comprising a plurality of user equipment and a network infrastructure. Radio resource of the plurality of cells is divided into more than one radio resource groups. A network infrastructure element detects a requirement of radio resource allocation for a user equipment and determines effective interference to be generated by the required radio resource to a defined group of neighbouring cells. User equipment is allocated a radio resource from one of the radio resource groups on the basis of the determined effective interference to be generated to the defined group of neighbouring cells. Inter-cell interference decreases and the throughput of the cellular system increases, but the exchange of physical layer information is not increased.

System and method for asynchronous update of indexes in a distributed database

An improved system and method for asynchronous update of indexes in a distributed database is provided. A database server may receive the request to update the data and may update the data in a primary data table of the distributed database. An asynchronous index update of the indexes may be initiated at the time a record is updated in a data table and then control may be returned to a client to perform another data update. An activity cache may be provided for caching the records updated by a client so that when the client requests a subsequent read, the updated records may be available in the activity cache to support the various guarantees for reading the data. Advantageously, the asynchronous index update scheme may provide increased performance and more scalability while efficiently maintaining indexes over database tables in a large scale, replicated, distributed database.

System and method for advertisements in web-based printing

A system and method for providing advertisements in web based printing. A remote printing web server receives advertisements from one or more advertisers. The advertisements may include target audience attributes, such as the profession of target audience members. Digital advertising images and the target audience information is stored on the remote printing web server. A print user connects to the remote printing web server using a browser. Information about the user, such as the user's occupation, are gathered in order to match the user with appropriate advertisements. Advertisements are identified and combined with the document that the user wishes to print. The combined document is then printed on a printer connected to the remote printing web server. In addition, the document that the user wishes to print may be analyzed for document content in order to further select appropriate advertisements to include on the user's printouts.

Apparatus and process for regenerating catalyst

Disclosed is an apparatus and process for prolonging the residence time of catalyst in a chamber for regenerating catalyst. Spent catalyst, perhaps from an FCC reactor, is introduced into a chamber of a regeneration vessel between lower and higher combustion gas distributors. The velocity of gas from the lower distributor is insufficient to entrain catalyst from the bed, and gas from the higher distributor when combined with gas rising from the lower distributor is sufficient to generate a fast fluidized flow condition. The second distributor elevates the location of the transition from turbulent bed to fast fluidized conditions.

User selection method in a zero-forcing beamforming algorithm

In a method for selecting a transmission target terminal in a zero-forcing beamforming algorithm, information about a channel capacity of each terminal is received from all K terminals. A terminal with a largest channel capacity is selected as an initial transmission target terminal. A determination is made as to whether the number of currently selected terminals, i, is equal to the predefined number N. If the number of currently selected terminals, i, is different from the predefined number N, information about channel capacities of remaining terminals except previously selected transmission target terminals is received until i is equal to N and a terminal with a largest channel capacity is selected as a transmission target terminal.
