Filed:

Aug 31, 2004

Appl. No.:

10/931622

Inventors:

Shin Funada - Pleasanton CA, US
Amritpal S. Rana - Union City CA, US
Daniel E. Scott - Fremont CA, US

Assignee:

Western Digital (Fremont), LLC - Fremont CA

International Classification:

B05D 5/12

US Classification:

427127, 427128, 427131, 2960327

Abstract:

A method and system for providing a magnetic element are described. The method and system include providing a pinned layer, fabricating a metallic spacer layer and oxidizing a portion of the spacer layer in an environment including at least oxygen and a gas inert with respect to the spacer layer to provide an oxide layer. The method and system also include creating a free layer. The oxide layer is between a remaining metallic portion of the spacer layer and the free layer. In one aspect, the system includes a chamber and a gas diffusion apparatus within the chamber. The gas diffusion apparatus includes a plurality of nozzles and defines a plane. The gas exits each of the plurality of nozzles in a cone having an apex angle. The nozzles are directed at a nozzle tilt angle of at least half of the apex angle from the plane and the spacer layer.

Irvine Optical Corporation - Burbank CA

International Classification:

G01N 2188

US Classification:

356237

Abstract:

A positioning system is provided for positioning a part or element in different inclinations relative to a plane normal to a central axis, and for also rotating the part about the central axis. A holder supporting the part is freely pivotable about a point on the central axis. A central spindle on the axis is coupled to a concentric tiltable ring assembly that is controllable in two directions of freedom from an input device. The tilt and rotational motions of the ring assembly are translated to the part holder by a multi-element linkage mechanism having low friction bearings at each end and allowing a wide range of motion. The part may be a semiconductor wafer to be inspected for flaws on a holder comprising a vacuum chuck. Alternatively the tiltable, rotatable mechanism may be used to support an optical camera or viewing device, or a robotic mechanism, for operation within a wide field.

Abstract:

An algorithmic real-time learning engine comprising an algorithmic model generator configured to process a set of system variables from a big data source using at least one of a pattern recognition algorithm and a statistical test algorithm to identify patterns, relationships between variables, and important variables; and generate at least one of: a predictive model based on the identified patterns, relationships between variables, and important variables; statistical test model about correlations, differences between variables, or patterns in time across variables; and recurring clusters model of similar observations across variables. A data preprocessor can select system variables of interest, align the selected system variables based on time, and arrange the aligned variables into rows. The selected system variables can also be aggregated based on a pre-defined aggregate. A visualization processor generates visualizations based on the set of system variables and the predictive model, the statistical test, or recurring cluster.
