摘要:
The CMP polishing liquid containing a medium and silica particles as an abrasive grain dispersed into the medium. The silica particles have a silanol group density of 5.0/nm2 or less and the biaxial average primary particle diameter when arbitrary 20 silica particles are selected from an image obtained by scanning electron microscope observation is 25 to 55 nm. The association degree of the silica particles is 1.1 or more. The CMP polishing liquid has the high barrier film polishing speed, the favorable abrasive grain dispersion stability, and the high interlayer dielectric polishing speed. The CMP polishing liquid can provide a method of producing semiconductor substrates or the like, that have excellent microfabrication, thin film formation, dimension accuracy, electric property and high reliability with low cost.

摘要:
A browser 21 of a mark user client 3 obtains Web page 11 from a mark provider server 2 and displays it. Then control is transferred to a mark reference program 22 when a mark is detected, and the program extracts digital watermark information from a mark image. This digital watermark information comprises referred data, and an action definition that includes an action class and an index of the referred data as a parameter. The mark reference program 22 refers to this action definition, refers to required data through the index included in the action definition, and then performs processing defined by the action class.
摘要:
An electronic application system comprises a local-government-shared server, a plurality of resident terminals and a plurality of local-government terminals. The local-government-shared server includes a first network connection unit, an encoded data converter apparatus, a reference table generation unit, a reference table storage unit, an encoded data storage unit, a second network connection unit, a reference table search unit and a data access control unit. The encoded data converter apparatus converts encoded data (generated by encoding application data to be transmitted from a resident terminal to a local-government terminal) of an external protocol into encoded data of an internal protocol while securing the confidentiality of plain text data which is obtained when the encoded data is temporarily decoded. For each application data, the encoded data converter apparatus generates a reference record so that the record can be referred to before the local-government terminal obtains the application data.
摘要:
An exchange servicing development support system automatically replaces definition contents and creates generation codes to new specifications, even if interfacing is changed, by reading servicing definition result files stored in accordance with old specifications. By providing a unit for re-constructing service tree structure data in a format in accordance with information about compatibility description in a menu describing file, the service tree structure data is automatically created. Since information about compatibility is allocated to the menu describing a file stored in the storage device, each unit in the data processing device is adapted to be used for a general purpose. The description of replacement of various patterns can be made by descriptions of information about compatibility in the menu describing file.
摘要:
An ordinary read/write operation (normal operation) and a refresh operation are separated from one another and the number of read amplification circuits or, in other words, the number of sense amplifiers operating during the normal operation is made smaller than that during the refresh operation. Accordingly, a bit line charge/discharge current during the normal operation can be reduced.
摘要:
A microprocessor or the like supplies a plurality of address signals for memory access according to its own operation speed irrespective of the operation speed of a memory. A plurality of registers receives and stores the plurality of address signals which are inputted in an asynchronous state. The memory access is performed according to a sequence signals of the address signals stored in the plurality of registers.
