Abstract: When performing a liquid processing on a substrate W being rotated and removing a processing liquid by a cleaning liquid, a cleaning liquid nozzle 421 configured to discharge a cleaning liquid slantly with respect to a surface of the substrate W toward a downstream side of a rotational direction of the substrate W and a gas nozzle 411 configured to discharge a gas toward a position adjacent to a central portion side of the substrate W when viewed from a liquid arrival position R of the cleaning liquid are moved from the central portion side toward a peripheral portion side. A rotation number of the substrate is varied such that rotation number in a period during which the liquid arrival position R moves in the second region becomes smaller than a maximum rotation number in a period during which the liquid arrival position moves in the first region.

Abstract: There is provided a guide member 3 in which an inclined surface 32 thereof is inclined downwardly outwards from an edge portion of a rear surface of a horizontally held wafer W; and a cylindrical surrounding member 2 which surrounds the wafer W and in which an upper peripheral portion thereof is inwardly extended obliquely upwards. Further, the surrounding member 2 has, at an inner surface side thereof, two groove portions 23 extended along an entire circumference and located above a height position of the horizontally held wafer W. If an air flow flows along the surrounding member 2, a vortex flow is formed within the groove portions 23 and stays therein. Thus, mist can be captured, so that the flow of the mist to the outside of a cup body 1 can be suppressed. Accordingly, the adhesion of the mist to the wafer W can be suppressed.

Abstract: A cleaning liquid and a gas are discharged in sequence to a central portion of a substrate while the substrate is being rotated, and after nozzles that discharge them are moved to a peripheral edge side of the substrate, discharge of the cleaning liquid is switched to a second cleaning liquid nozzle set at a position deviated from a movement locus of the first cleaning liquid nozzle. Both of the nozzles are moved toward the peripheral edge side of the substrate while discharging the cleaning liquid and discharging the gas so that a difference between a distance from the discharge position of the second cleaning liquid nozzle to the central portion of the substrate and a distance from the discharge position of the gas nozzle to the central portion of the substrate gradually decreases.

Abstract: A substrate cleaning method is capable of preventing a liquid stream on a substrate from being cut and circuit patterns thereon from being damaged. The substrate cleaning method includes a liquid film forming process that forms a liquid film on an entire substrate surface by supplying a cleaning liquid L from a central portion of the substrate W toward a peripheral portion thereof while rotating the substrate; a drying region forming process that discharges a gas G on the substrate surface and removes the cleaning liquid on the substrate surface; and a residual liquid removing process that removes the cleaning liquid remaining between the circuit patterns by discharging a gas G while moving in a diametrical direction of the substrate.

Abstract: A disk array controller is connected to both a host computer and a plurality of disk drives operating in parallel. The disk array controller is responsive to an output request from the host computer for dividing data supplied from the host computer and parallel writing the divided data in the plurality of disk drives. In response to an input request from the host computer, the disk array controller combines data parallelly read from the disk drives into a set of data. Responsive to the output request, a processor stores in a non-volatile memory a write status of each block within a data write area for each disk drive to which data is to be written. The write status includes a first status representing a write completed status of each disk drive, a second status representing a writing status of each disk drive, and a third status representing a no write indication status of each disk drive.

Abstract: A storage control unit is connected between a central processing unit having an interface for accessing a first disk unit into which data constructed of a plurality of variable length data records are stored in a first recording format, and a second disk unit into which data constructed of a plurality of fixed length data blocks are recorded in a second recording format. The storage control unit contains a plurality of first-level storage regions having a storage capacity equal to a track of the first disk unit, and the first-level storage regions have a plurality of cache memories constructed of a plurality of second-level storage regions having storage capacities equal to the fixed length blocks in the second recording format.

Abstract: Block data of logical inconsistency stored in a disk array is inhibited to be transferred to a host computer, by detecting a range where data was written defectively because of a power cut or the like. A processor of a disk array controller allocates a write control table within a non-volatile memory when writing data to a drive group. The write status of each disk drive in each block is supervised by a write status flag. The write statuses include a no write indication status, a writing status, and a write completed status. If all the write statuses of the same block are the write completed status or no write indication status, data is transferred to the host computer. If all the data write statuses of the same block are neither the write completed status nor no write indication status, a read error is informed to the host computer.
