摘要:
A flip chip semiconductor device has a substrate with a plurality of active devices formed thereon. A passive device is formed on the substrate by depositing a first conductive layer over the substrate, depositing an insulating layer over the first conductive layer, and depositing a second conductive layer over the insulating layer. The passive device is a metal-insulator-metal capacitor. The deposition of the insulating layer and first and second conductive layers is performed without photolithography. An under bump metallization (UBM) layer is formed on the substrate in electrical contact with the plurality of active devices. A solder bump is formed over the UBM layer. The passive device can also be a resistor by depositing a resistive layer over the first conductive layer and depositing a third conductive layer over the resistive layer. The passive device electrically contacts the solder bump.

A novel disk drive head stack assembly (HSA) includes a first head gimbal assembly attached to a first actuator arm. A dummy mass is attached to a second actuator arm. The dummy mass includes a mounting plate portion defining a mounting plate width. The mounting plate portion includes first and second projections. The dummy mass also includes a neck portion defining a neck width and a neck length. A root portion of the neck portion is disposed between the first and second projections, and defines first and second alcoves between the root portion and the first and second projections, respectively. The dummy mass also includes a distal mass portion defining a distal mass width and a distal mass length. The neck width is less than the mounting plate width, and the neck width is less than the distal mass width.

A mechanism is provided for archiving and restoring transaction files of a database system without requiring the copying of the transaction files. A server system executes a host application that implements the database system comprising a set of database files and a set of transaction files that contains updates to the set of database files, the files being stored in a storage system. A backup engine interacts with the host application to archive a transaction file having an original filename in an original directory by creating a corresponding archive filename to the transaction file in an archive directory. The archive transaction files may be used later to perform a copy-less restore process of the database system that does not require copying of any transaction files. The copy-less restore process restores any altered original filenames by replacing, in the original directory, an altered original filename with its corresponding archive filename.

A method and apparatus for providing a distributed service composition model in accordance with the characteristics of an ad hoc network are provided. The method includes confirming whether an adjacent mobile node exists within a number of hops from a task initiator node so as to execute a task, establishing a flow for executing the task with regard to the adjacent mobile node if it is confirmed that the adjacent mobile node exists, and executing the task using a routing algorithm in accordance with the flow. At least one service necessary to execute the task and an execution order between services are determined based on cooperation between adjacent mobile nodes.
摘要:
A method of manufacturing a semiconductor device includes providing a substrate with an insulation layer disposed on a top surface of the substrate, forming a passive device over the top surface of the substrate, removing the substrate, depositing an insulating polymer film layer over the insulation layer, and depositing a metal layer over the insulating polymer film layer. A solder mask can be formed over the metal layer. A conformal metal layer can then be formed over the solder mask. A notch can be formed in the insulation layer to enhance the connection between the insulating polymer film layer and the insulation layer. Additional semiconductor die can be electrically connected to the passive device. The substrate is removed by removing a first amount of the substrate using a back grind process, and then removing a second amount of the substrate using a wet dry, dry etch, or chemical-mechanical planarization process.
摘要:
A semiconductor device has a substrate with an inductor formed on its surface. First and second contact pads are formed on the substrate. A passivation layer is formed over the substrate and first and second contact pads. An insulating layer is formed over the passivation layer. The insulating layer is removed over the first contact pad, but not from the second contact pad. A metal layer is formed over the first contact pad. The metal layer is coiled on the surface of the substrate to produce inductive properties. The formation of the metal layer involves use of a wet etchant. The second contact pad is protected from the wet etchant by the insulating layer. The insulating layer is removed from the second contact pad after forming the metal layer over the first contact pad. An external connection is formed on the second contact pad.

Data synchronization includes establishing a plurality of target data tables based on a source data table in which data to be synchronized is stored, determining a current target data table from the plurality of target data tables, synchronizing the source data table and the current target data table, and directing an application server to access the current target data table upon successful completion of synchronization.
摘要:
A flip chip semiconductor device has a substrate with a plurality of active devices formed thereon. A contact pad is formed on the substrate in electrical contact with the plurality of active devices. A passivation layer is formed over the substrate and intermediate conduction layer. An adhesive layer is formed over the passivation layer. A barrier layer is formed over the adhesive layer. A wetting layer is formed over the barrier layer. The barrier layer and wetting layer in a first region are removed, while the barrier layer, wetting layer, and adhesive layer in a second region are maintained. The adhesive layer over the passivation layer in the first region are maintained until the solder bumps are formed. By keeping the adhesive layer over the passivation layer until after formation of the solder bumps, less cracking occurs in the passivation layer.
