Elektrisch leitender Kontakt- oder Metallisierungsaufbau für integrierte Schaltungen unter Verwendung von Sperrschichten (8) aus TiW und ausgewählten Übergangsmetallen zwischen Gold (10) und einem Siliciumsubstrat (1), wobei das Übergangsmetall (9) eine zusätzliche Sperrschicht oder eine Schicht einer aus dem Übergangsmetall und Gold gebildeten intermetallischen Verbindung enthält. Ferner ist die Verwendung einer Platinsilicidschicht (7) zwischen TiW-Schicht (8) und Silicium (1) zur Bildung von Schottky-Sperrschichtkontakten (4) erwähnt.
摘要:
A magnetoresistive read sensor incorporates a granular multilayer sensing element comprising a plurality of layers of generally flat particles (31) of a ferromagnetic material embedded in a nonmagnetic electrically conductive material. A bias layer (45) separated from the magnetoresistive sensing element by a spacer layer (43) provides a magnetic field to bias the magnetoresistive sensing element at a desired non-signal point. The ferromagnetic and the nonmagnetic materials are mutually immiscible, or may be miscible or partially miscible and processed in a manner to control interdiffusion. The magnetoresistive sensing element is formed by alternatively depositing layers of ferromagnetic material and layers of nonmagnetic conductive material on a substrate and then annealing the structure. During the annealing cycle, the layers of nonmagnetic material above and below the ferromagnetic layers penetrate at grain boundaries and break the continuity of the ferromagnetic layers to form layers or planes of ferromagnetic particles embedded in a matrix of nonmagnetic material.
摘要:
A magnetic recording disk has an improved surface film formed on the disk blank. A sputter-deposited surface coating containing nickel, chromium and oxygen (Ni-Cr-O) is formed on a AlMg disk blank, after which a cobalt alloy magnetic layer is formed over the Ni-Cr-O coating and a protective overcoat is formed over magnetic layer. The use of the Ni-Cr-O coating on the disk blank eliminates the need for a wet electroless deposition process for creation of a surface coating and results in an inherent texturing of the subsequently deposited magnetic film and protective overcoat which conform to the surface texture of the sputter-deposited Ni-Cr-O. The disks made with the Ni-Cr-O surface film exhibit a very law static friction force between the air-bearing slider and the disk surface when the disks are used in contact start/stop (CSS) disk files.
