Filed:

Aug 16, 2002

Appl. No.:

10/223226

Inventors:

Albert Wang - Moraga CA
Robert Chen - El Sobrante CA

Assignee:

Matrix Integrated Systems, Inc. - Richmond CA

International Classification:

H05B 368

US Classification:

2194441, 296101

Abstract:

Methods and structures are provided for extremely flat wafer chucks, allowing close thermal contact uniformly across a semiconductor processing substrate. An upper and a lower section are tightly fit to one another with flat inner surfaces in face-to-face contact. The sections also define at least one groove therebetween. The two sections have asymmetrical thickness, but the groove defined therebetween is correspondingly asymmetrical such that the groove is centered in the assembled chuck. A heater element, such as a resistive heater, is placed within the groove with some clearance prior to assembling the upper and lower sections. After assembly and tightening, the chuck is thermally cycled above the normal operating temperature prior to secondary machining, thus assuring flatness that is maintained during high temperature operation.

Abstract:

A coil is provided for use in a semiconductor processing system to generate a plasma with a magnetic field in a chamber. The coil comprises a first coil segment, a second coil segment and an internal balance capacitor. The first coils segment has a first end and a second end. The first end of the coil segment is adapted to connect to a power source. The second coil segment has a first and second end. The second end of the first coil segment is adapted to connect to an external balance capacitor. The internal balance capacitor is connected in series between the second end of the first coil segment and the first end of the second coil segment. The internal balance capacitor and the coil segments are adapted to provide a voltage peak along the first coil segment substantially aligned with a virtual ground along the second coil segment.

International Classification:

G11B 9/00

US Classification:

369126

Abstract:

A data storage medium includes a piezoelectric film () having a surface () including a halogen. In one embodiment, the halogen exists in an atomic concentration of at least approximately 10 percent. The result is a hydrophobic surface conducive to long-lasting scanning probe tips, low contamination, and stable surface charge. A data storage device incorporating the data storage medium includes an enclosure () containing the data storage medium and an adjacent scanning probe () wherein the enclosure has a relative humidity of at least approximately 40 percent and at least a portion of the scanning probe is coated with a layer of water.

US Classification:

717133

Abstract:

A system and method for monitoring dynamic scopes in a runtime environment is disclosed. The system and method utilizes an algorithm which may be applied to both synchronous and asynchronous invocations. The method comprises determining an initial scope of a source component, the initial scope being a scope of the source component upon providing a synchronous call to invoke a target component. The scope declaration specified by the target component is determined. A resultant scope present upon invocation of the target component is then determined. The resultant scope is determined based on the initial scope of the source component and the scope declaration specified by the target component. A record is stored in a centralized location identifying the resultant scope, and the target component as a participant in the resultant scope.
