摘要： Source/drain diffusion regions are formed on the silicon substrate such that the source/drain diffusion regions sandwich a gate electrode from both sides on the silicon substrate. Sidewall oxide films are formed, one on each side surface of the gate electrode. Recessed portions are formed in the extension portions E beneath the sidewall oxide films. Source/drain electrodes are formed to fill the recessed portions. Thus, the sheet resistance of the respective regions including a pair of source/drain diffusion regions and source/drain electrodes is reduced, and a semiconductor device with a field-effect transistor having an improved current drivability is obtained.

摘要： Epitaxial silicon layers are formed on n+-source/drain regions of two MOS transistors neighboring to each other and formed on a silicon substrate, respectively. In this processing, polycrystalline silicon pieces are generated on an element isolating and insulating film and others. Thereafter, the silicon substrate is exposed to an oxygen atmosphere so that hydrogen reacts with silicon at the surfaces of the epitaxial silicon layers and the surfaces of the polycrystalline silicon pieces to form silicon oxide films and polycrystalline silicon pieces. Thereby, short-circuit between MOS transistors in neighboring memory cells is prevented, and a semiconductor device has a high electrical reliability.

摘要： A system which includes at least one client, a plurality of file servers, each having a file system, and a switch logically arranged between the client and the plurality of file servers to provide file access services which virtually render the plurality of file systems accessible as a single file system, termed a ‘pseudo file system’, when viewed from the terminal. The switch distributes a command that starts generation of snapshots to the plurality of file servers, which file servers formulate respective snapshots responsive to the command that starts formation of the snapshots. The switch sets the plurality of snapshots, generated by the plurality of file servers, so as to be associated with the file system structure of the virtual file system at the time of formation of the snapshots.

摘要： Each of the sites interconnected to one another through a wide area network includes at least one client, a switch device logically disposed between the client and at least one server including a storage device, for providing to the client a file access virtually unifying of a plurality of storage devices, and an analysis device connected to the switch device. The switch device takes log information on the file access from the client. The analysis device determines data to be migrated to the server in a site to which the client belongs or the server in a site in vicinity of the site to which the client belongs, and commands the switch device to migrate the data. The switch device migrates the data based on the command from the analysis device.

摘要： An intermediate device which can be introduced and removed in seamless way is disclosed. The state information acquiring means acquires state information required to maintain the state of a session established between the first information processing device and the second information processing device for the information processing service, from the first information processing device or the second information processing device. The intermediate service managing means generates, based on the state information, transfer rules for applying the intermediate service to data of the information processing service, and transferring the data to which the intermediate service is applied. The transfer control means maintains the state of the existing session between itself and the second information processing device, establishes a new session between itself and the first information processing device, and transfers the data using the existing session and the new session, according to the transfer rules.
