Filed:

Appl. No.:

09/597850

Inventors:

Evan F. Cromwell - Redwood City CA
Johann F. Adam - Palo Alto CA

Assignee:

Katsina Optics, Inc. - Milpitas CA

International Classification:

G01N 2188

US Classification:

2505594, 2502015

Abstract:

A laser scatterometer used, e. g. , to detect defects on memory media, includes a beam block that can be finely adjusted so as to block specular light while maximizing the small angle scattered light that is received by the light detector. The beam block may be adjusted independently of the light detector or may be a masked beam block that is adjusted with the entire light detector. The light source produces a light beam that is focused so as to maximize the spot size on the object being tested while minimizing the spot size at the beam block, which advantageously maximizes the small angle scattered light while decreasing testing time. The large spot size at the object being tested permits detection of large defects. Thus, disks may be quickly tested, e. g. , during the burnishing process, to determine if there are any large defects.

International Classification:

A47L 1500

US Classification:

15 883, 15 77, 15102, 134140, 134149, 134157, 134902

Abstract:

A washer includes driving and scrubbing rollers that press against the opposing surfaces of a substrate, which may be, e. g. , a small form factor disk. The driving rollers and scrubbing rollers are approximately aligned along two different radii of the substrate that are separated by 180 degrees. The driving rollers rotate in opposite directions as do the scrubbing rollers. During the scrub cycle, the driving rollers cause the substrate to rotate, while the scrubbing rollers scrub the opposing surfaces of the substrate. Outside diameter rollers that are orthogonally positioned relative to the driving rollers and the scrubbing rollers, and which may be free spinning, contact the outside diameter of the substrate and hold the substrate in position during the scrub cycle. The substrate is loaded into the washer by lifting the substrate, via a lifting arm, to the driving and scrubbing rollers. The rotation of the driving and scrubbing rollers pulls the substrate into position with the outside diameter of the substrate in contact with the outside diameter rollers.

International Classification:

US Classification:

Abstract:

A sputter pallet loading and unloading device includes in one embodiment a spindle that rotates the pallet while an arm is engaged with the spring in the pallet to open and close the spring. In another embodiment, the spindle is located adjacent an air track that moves the disk substrate over a cushion of air to the loading area of the pallet. The air pressure under the disk substrate is increased to raise the disk substrate into the loading area. Once raised into the loading area, the spring is closed, e. g. , by rotating the pallet in the opposite direction. The pallet and air-track are at a small angle to allow the substrate to slide into the correct position. The simplicity of operation leads to a reduced cost and a higher throughput for this device compared to a robotic loader.

Assignee:

Toda Citron Technology, Inc. - Milpitas CA

International Classification:

B05C 1902

US Classification:

118423, 118503

Abstract:

A system for processing a disk includes an end-effector having a plurality of fingers. The end-effector is mounted to a rotary actuator. The rotary actuator is mounted to a linear stage. The linear stage is positioned adjacent to an air track and a tank. The rotary actuator and the linear stage place the fingers into the inner diameter of a disk on the air track. The fingers grip the inner diameter of the disk. The rotary actuator and the liner stage then place the fingers holding the disk into the tank. The tank is filled with a processing liquid such as a lubrication solution to lubricate the disk.

Abstract:

An air track includes a concave top surface with a plurality of air outlets or a flat surface with a notch and a plurality of air outlets. The body of the air track includes at least one air filter that runs along the length of at least a portion of the body. The air filter divides the body into a first plenum and a second plenum. The air track also includes a hood covering at least a portion of the top surface. The air track further includes a stopper assembly that arrests the motion of a disk. The stopper assembly includes a disk detector that senses the presence of the disk on the air track.
