Filed:

Jul 27, 2004

Appl. No.:

10/900938

Inventors:

Larry Wayne Shive - St. Charles MO, US
Brian Lawrence Gilmore - Richardson TX, US

Assignee:

MEMC Electronic Materials, Inc. - St. Peters MO

International Classification:

H01L 29/15

US Classification:

257 77, 438745, 438753, 216100

Abstract:

Processes for the purification of silicon carbide structures, including silicon carbide coated silicon carbide structures, are disclosed. The processes described can reduce the amount of iron contamination in a silicon carbide structure by 100 to 1000 times. After purification, the silicon carbide structures are suitable for use in high temperature silicon wafer processing.

H01L 21/324

US Classification:

438795, 438571, 438770, 438776, 438789, 438799, 257347, 257682, 257E21328, 257E21285, 257E21639

Abstract:

A process is disclosed for annealing a single crystal silicon wafer having a front surface and a back surface, and an oxide layer disposed on the front surface of the wafer extending over substantially all of the radial width. The process includes annealing the wafer in an annealing chamber having an atmosphere comprising oxygen. The process also includes maintaining a partial pressure of water above a predetermined value such that the wafer maintains the oxide layer through the annealing process. The annealed front surface is substantially free of boron and phosphorus.

Assignee:

MEMC Electronic Materials, Inc. - St. Peters MO

International Classification:

A47G 19/08

US Classification:

211 4118

Abstract:

A support for a semiconductor wafer includes a plate having a support surface for supporting the wafer and a recessed surface spaced from the support surface and spaced from the wafer. A plurality of holes extends from the recessed surface, and the support surface is free of holes to inhibit contamination of the wafer.

H01Q 3/06

Abstract:

A control system and method is provided for raising and lowering a vehicle antenna. The control system includes a location receiver for generating vehicle location data, an obstacle detection unit which generates an obstacle signal, an antenna, an antenna motor for raising and lowering the antenna and a control unit. The control unit controls the antenna motor as a function of the vehicle location data and the obstacle signal. The control unit compares the vehicle location signal to stored or received geofencing information defining a geofenced area, and causes the antenna motor to raise the antenna when the vehicle location corresponding to the vehicle location data is inside the geofenced area and no obstacle is detected. The control unit causes the antenna motor to lower the antenna when the vehicle location corresponding to the vehicle location data is outside the geofenced area or if an obstacle is detected.
