Abstract: A system, method and medium for controlling a wafer processing chamber using two or more processors (within one or more computer processing systems), wherein specified functions are assigned to each processor. Some embodiments contemplate that each processor may reside within its own computer processor system (each computer processor system being in communication with the other), wherein each computer processor system implements specified functions to control and maintain certain parameters involved in the manufacture of the wafer. This allows the present invention to react quickly to maintain rapidly-changing desired conditions within a wafer processing chamber and to maintain a greater degree of uniformity of those conditions throughout the wafer.

Abstract: A dispense nozzle (10), having a narrow oblong orifice (14), is positioned over and near the surface of the substrate (22), close to the edge of the substrate. While the substrate is rotating, the nozzle dispenses fluid through the narrow oblong orifice onto the substrate surface, starting from near the outer edge (24) moving toward the substrate's rotational center (26). The narrow oblong orifice may have lips of unequal size to help direct fluid flow. A controlled rate of acceleration is maintained for the rate of translation of the nozzle across the substrate surface. Once the nozzle approaches the substrate's rotational center, the nozzle is raised to a higher height above the surface of the substrate while continuing to dispense fluid. Then the dispense stream of fluid is terminated, and the substrate is rapidly accelerated to a predetermined spin speed to evenly distribute the fluid over the surface of the substrate to a uniform film of desired thickness.

Abstract: Provided herein is a CVD method and apparatus for the deposition of tungsten in which formation of a film of tungsten material is suppressed at the peripheral edge of the semiconductor substrate. In accordance with the invention, a halogenide purge gas is supplied to the peripheral edge of the processing face of a semiconductor wafer during the chemical vapor deposition of tungsten. The halogenide purge gases interact with the processing gases and form a passivation film at the peripheral edge of the semiconductor wafer which suppresses or prevents the formation of a film of tungsten material on the edge surface. Consequently, CMP can be applied to the tungsten semiconductor wafer, and particles of the tungsten material, etc., are not generated from the intense polishing of the peripheral edge of the wafer. Therefore, an uncontaminated tungsten-coated semiconductor wafer with a precise multilayer electrode wiring structure can be manufactured in large volume and favorable yields.

Abstract: An apparatus for polishing semiconductor wafers and other workpieces that includes a polishing pads mounted on respective platens at multiple polishing stations. Multiple wafer heads, at least one greater in number than the number of polishing stations, can be loaded with individual wafers. The wafer heads are suspended from a carousel, which provides circumferential positioning of the heads relative to the polishing pads, and the wafer heads oscillate radially as supported by the carousel to sweep linearly across the respective pads in radial directions with respect to the rotatable carousel. Each polishing station includes a pad conditioner to recondition the polishing pad so that it retains a high polishing rate. Washing stations may be disposed between polishing stations and between the polishing stations and a transfer and washing station to wash the wafer as the carousel moves. A transfer and washing station is disposed similarly to the polishing pads.
