US Patent:

6689264, Feb 10, 2004

Filed:

Sep 4, 1997

Appl. No.:

08/923103

Inventors:

Charles I. Belisle - Austin TX
Michael L. Stephan - Pflugerville TX

Assignee:

Cypress Semiconductor Corp. - San Jose CA

International Classification:

C23C 1434

US Classification:

20429815, 15634551, 118500, 118503, 118728

Abstract:

An improved wafer clamp retainer is provided. The retainer is used to movably secure a wafer clamp to an upper electrode within a parallel-plate reactor. When drawn downward, the wafer clamp is pressed by the retainer against an outer periphery of the wafer to hold the wafer against the lower electrode. When drawn upward, the retainer lifts the wafer clamp from the wafer so that the wafer can be accessed. The wafer clamp retainer includes one or more features formed about an outer surface of a shaft extending from one end of the retainer body. The feature can comprise one or more rings, or spiral threads which mate with a flexible washer. The washer can be pushed directly upon the shaft and snap-fitted with the features or, alternatively, threaded upon the shaft by employing mating features on the wall which surrounds the opening through the washer. The combination of an improved retainer and improved washer minimizes possibility of breaking the retainer when performing periodic maintenance upon the wafer clamp.

Abstract:

A bottle has a body intermediate a neck and a closed bottom of the bottle. The body has an exterior surface defining a circumference of the body. The body includes a plurality of panel segments. Each panel segment has an upper panel end, a lower panel end, a length extending from the upper panel end to the lower panel end, opposite longitudinal sides, and a panel centerline extending at a substantially constant acute angle relative to the longitudinal axis of the bottle. The panel segments are disposed generally side-by-side around the circumference of the body. The exterior surface of each panel segment may be substantially planar along the circumferential width of the panel segment.
