Appl. No.:

10/053785

Inventors:

Mike Chen - Daly City CA, US
Thomas Dinan - San Jose CA, US
Neil Robertson - Palo Alto CA, US

Assignee:

INTERNATIONAL BUSINESS MACHINES CORPORATION

International Classification:

C25C003/36

US Classification:

205/365000

Abstract:

A process for electroplating and annealing thin-films of nickel-iron alloys having from 63% to 81% iron content by weight to produce pole pieces having saturation flux density (B) in the range from 1.9 to 2.3 T (19 to 23 kG) with acceptable magnetic anisotropy and magnetostriction and a coercivity (H) no higher than 160 A/m (2 Oe). The desired alloy layer properties, including small crystal size and minimal impurity inclusions, can be produced by including higher relative levels of Fe ions in the electroplating bath while holding the bath at a lower temperature while plating from a suitable seed layer. The resulting alloy layer adopts a small crystal size (BCC) without significant inclusion of impurities, which advantageously permits annealing to an acceptable Hwhile retaining the high Bdesired.

International Classification:

G11B021/02

US Classification:

360/071000, 360/075000

Abstract:

A thin-film write head employing pole pieces formed of an electroplated body-centered cubic (BCC) nickel-iron alloy with a saturation flux density (B) of 1.9 to 2.3 T (19 to 23 kG) and an acceptable coercivity (H) of about 80 to about 160 A/m (1-2 Oe). The iron content of the electroplated nickel-iron alloy is from 64% to 81% by weight. The two-layer pole fabrication process holds magnetic anisotropy and coercivity to useable values while improving saturation flux density and optimizing magnetostriction. This is accomplished by first electroplating a BCC nickel-iron layer onto an underlying seed layer and then annealing the two layers to reduce coercivity to less than about 160 amps/meter and raise magnetization to acceptable levels.

Abstract:

Certain embodiments include an etching method including providing an etch material, applying a gas mixture including hydrogen, forming a plasma, and etching the etch material. The etch material can include a low-k dielectric material. The gas mixture can include a hydrogen gas, a hydrogen-free fluorocarbon, and a nitrogen gas, and further include one or more of a hydrofluorocarbon gas, an inert gas, and/or a carbon monoxide gas. The hydrogen gas can be a diatomic hydrogen, a hydrocarbon, a silane and/or a fluorine-free hydrogen gas, including H, CH, CH, NH, and/or HO gases. The hydrogen-free fluorocarbon gas can be a CFgas (where x≧1 and Y≧1) and the hydrofluorocarbon gas can be a CHFgas (where x≧1, y≧1 and z≧1). The gas mixture can be free of oxygen. Embodiments can include reduced pressures, reduced hydrogen flow rates and one or more plasma frequencies.

International Classification:

G11C 700
H03K 190175

US Classification:

36518911

Abstract:

In this invention external high voltages are connected to a chip containing a flash memory that are connected to selected cells to be erased. Internal pump circuits contained on the chip are turned off while the external voltages are used. The external voltages, a high negative voltage and a high positive voltage, are connected to gates and sources respectively of selected cells to be erased by a voltage control module. The external voltages are used during manufacture during program/erase operations to perform the erase function efficiently. The internal high voltage pump circuits are used to erase flash memory cells after being assembled on a circuit board by a user. Two level shifter circuits are disclosed that form a part of the voltage control module. The level shifter circuits apply voltages to the flash memory cells and provide voltages that select and deselect the cells for erasure.

Abstract:

Social media networking applications, web sites, and services creates implicit relationships between users based on their interest or participation in real-world and optionally virtual or online activities in addition to explicitly defined peer relationships. User profiles, activity entities, and expressions may be associated with metadata to assist in searching and navigation. Metadata is implicitly associated with user profiles, activity entities, expressions, or other data entities based on user behavior using metadata collector. A metadata collector is a poll, survey, list, questionnaire, census, test, game, or other type of presentation adapted to solicit user interaction. A metadata collector is associated with metadata elements. When users interact with a metadata collector, their user profiles and the data entities included in their interactions become associated with the metadata elements of the metadata collector. These metadata element associations may then be used for any purpose.

International Classification:

G06F 12/0891

Abstract:

In a processing system in which at least one entity issues data read and write requests to at least one storage system that stores data as data units, pluralities of data units are grouped. Each group is written as a respective cache line in a cache, which is deduplicated. Before evicting a selected one of the cache lines, a caching component determines whether at least one of the data units in the selected cache line is still active; if so, then the still active data unit(s) in the selected cache line is read and written to a different cache line.
