The mechanism (28, 30) is located in the lower section beneath the cell (12) intermediate section (24), while the automaton is arranged in the top section, the mechanism and the automaton being accessible on the second surface (16) side.
Abstract:
A method and apparatus for polishing and planarizing workpieces such as semiconductor wafers is presented. Conditioning rings, which are used to condition polishing pads used in the planarization or polishing of semiconductor wafers, are shown which utilize brazed diamond technology in association with a coating of a titanium nitride containing composition or a thin film diamond deposition in order to reduce the fracturing and loss of cutting elements bonded to the conditioning ring.

Abstract:
A measurement of polyurethane pad characteristics is used to predict performance characteristics of polyurethane pads used for chemical mechanical planarization (CMP) of semiconductor wafers, and to adjust process parameters for manufacturing polyurethane pads. In-situ fluorescence measurements of a pad that has been exposed to a high pH and high temperature environment are performed. The fluorescence characteristics of the pad are used to predict the rate of planarization of a wafer. A portion of one pad from a manufacturing lot is soaked in an organic solvent which causes the portion to swell. The relative increase in size is indicative of the performance characteristics of pads within the manufacturing lot. Statistical Process Control methods are used to optimize the CMP pad manufacturing process. Predicted pad characteristics are available for each pad.

Abstract:
Processe and system for preparing a vehicle surface (e.g., an aircraft fuselage) for painting include a preparation booth (100) which is sized and configured to house the vehicle (F). At least one robotic assembly (200a, 200b) is reciprocally movable within the preparation booth (100) relative to a longitudinal axis of the vehicle (F), and is provided with a robotic hand (230) having at least one abrasive disc (242a) attached to an attachment pad (242) of the robotic hand (230), and at least one nozzle (252a, 252b, 252c) for discharging a stream of rinse fluid. Operation of the at least one robotic assembly (230) will cause the at least one abrasive disc (242a) of the robot hand (230) to abrade the surface of the vehicle (F). The robotic hand (230) may thereafter be maneuvered so that the at least one nozzle (252a, 252b, 252c) is directed toward the abraded vehicle surface (F). A stream of rinse fluid may then be discharged through the at least one nozzle (252a, 252b, 252c) and towards the abraded surface of the vehicle (F) so as to rinse the abraded surface of particulate matter.
Abstract:
The present invention relates to methods of using amidoxime compositions for cleaning polishing pads, particularly after chemical mechanical planarization or polishing is provided. A polishing pad is cleaned of Cu CMP by-products, subsequent to or during planarizing a wafer, to reduce pad-glazing by applying to the polishing pad surface a composition comprising an aqueous amidoxime compound solution in water.
