摘要:
A processing speed is improved when there is a pattern in which read requests making access to continuous areas in an LBA space repeatedly alternate with write requests making access to continuous or non-continuous areas in the LBA space. In one embodiment, when the pattern in which read requests making access to continuous areas in an LBA space repeatedly alternate with write requests making access to continuous or non-continuous areas in the LBA space is extracted or a notice that the pattern has occurred is given from a host, write data required by write requests is buffered while executing read requests, and when this buffering of the write data is started, the position at which write data is started to be written is set to a position where the capacity of the buffered write data maximizes, taking account of the ratio of the amount of data transferred to a cache memory during reading to the amount of data transferred to the cache memory during writing.

The present invention relates to a semiconductor device and a method for manufacturing the same. The semiconductor device has an embedded interconnect structure in which an electric conductor, such as copper or silver, is embedded in fine recesses formed in a surface of a semiconductor substrate, and also has a protective film formed on surfaces of exposed interconnects that define the interconnect structure, to protect the interconnects. The protective film has a flattened surface.

A coreless thermal transfer recording web roll 10 is formed by rolling a thermal transfer recording web 10a in a roll. An inner end part 11 of the thermal transfer recording web 10a of the thermal transfer recording web roll 10 has a tab 11a formed at a substantially middle of the inner end part 11, and sticking parts 11b formed on the opposite sides of the tab 11a, respectively. Pseudoadhesive double-coated tapes 14 are attached to the sticking parts 11b, respectively. The pseudoadhesive double-coated tapes become tack-free after the sticking parts 11b have been separated from the innermost layer of the thermal transfer recording web 10a of the thermal transfer recording web roll 10.
摘要:
A substrate processing apparatus fills a metal such as copper or the like in fine interconnection patterns or trenches defined in a semiconductor substrate. The substrate processing apparatus has a loading/unloading unit for placing a substrate cassette to allow a substrate to be loaded and unloaded, a substrate treating unit for treating a substrate, and a transfer robot for transferring a substrate between the loading/unloading unit and the substrate treating unit. The loading/unloading unit, the substrate treating unit, and the transfer robot are installed in a single facility. The loading/unloading unit has a rotary table which is horizontally rotatable for positioning the substrate cassette in a position to detect the substrate cassette placed in the loading/unloading unit and to remove the substrate from the substrate cassette with the transfer robot.

A plating method and apparatus for a substrate fills a metal, e.g., copper, into a fine interconnection pattern formed in a semiconductor substrate. The apparatus has a substrate holding portion 36 horizontally holding and rotating a substrate with its surface to be plated facing upward. A seal material 90 contacts a peripheral edge portion of the surface, sealing the portion in a watertight manner. A cathode electrode 88 passes an electric current upon contact with the substrate. A cathode portion 38 rotates integrally with the substrate holding portion 36. An electrode arm portion 30 is above the cathode portion 38 and movable horizontally and vertically and has an anode 98 face-down. Plating liquid is poured into a space between the surface to be plated and the anode 98 brought close to the surface to be plated. Thus, plating treatment and treatments incidental thereto can be performed by a single unit.

A thermal transfer printer includes a thermal transfer recording web roll having a bore and obtained by rolling a thermal transfer web. The segment of the thermal transfer recording web forming the innermost layer of the thermal transfer recording web roll is fixed to a part of a segment of the same forming the second innermost layer of the thermal transfer recording web roll. A holding device is inserted in the bore of the thermal transfer recording web roll to hold the thermal transfer recording web roll. The thermal transfer recording web roll and the holding device rotate in a unit to feed the thermal transfer recording web to a thermal transfer recording unit that forms images on the thermal transfer recording web. The thermal transfer recording web roll can be prepared at a low cost without requiring much time and effort.

The present semiconductor element comprises a semiconductor substrate, a wiring pad formed thereon, a layer of barrier metal formed thereon, an intermetallic compound Ag3Sn formed thereon, and a protruded electrode consisting of low-melting metal formed thereon. In addition, a fabricating method of a semiconductor element comprises the steps of forming a wiring pad on a semiconductor substrate, forming a layer of barrier metal thereon, forming a metallic layer containing Ag thereon, forming a layer of low-melting metal containing Sn thereon, and melting the layer of low-melting metal containing Sn to form a protruded electrode and simultaneously to form an intermetallic compound Ag3Sn at an interface between the metallic layer containing Ag and the layer of low-melting metal containing Sn. Thus, with Pb-free solder, a semiconductor element of high reliability can be obtained.
