摘要:
A pod loading station and method of operation are provided for enabling the transfer and introduction of wafers into a processing system from a wafer pod. The pod loading station generally includes a movable receiving platform for supporting a wafer pod and a movable pod door receiver having a pod door latch actuating mechanism disposed thereon. The movable platform supports a wafer pod, moves the wafer pod into engagement with the pod door receiver, and then retracts to enable the door supported by the door receiver to be removed from the opening of the pod. The pod door receiver then lowers the pod door below the pod to enable access to the pod opening.

A carrier head with a flexible member connected to a base to define a first chamber, a second chamber and a third chamber. A lower surface of the flexible member provides a substrate receiving surface with an inner portion associated with the first chamber, a substantially annular middle portion surrounding the inner portion and associated with the second chamber, and a substantially annular outer portion surrounding the middle portion and associated with the third chamber. The width of the outer portion may be significantly less than the width of the middle portion. The carrier head may also include a flange connected to a drive shaft and a gimbal pivotally connecting the flange to the base.

An apparatus and method for polishing semiconductor wafers and other workpieces that includes a polishing pads mounted on respective platens at multiple polishing stations. A transfer and washing station is disposed similarly to the polishing pads. The carousel simultaneously positions one of the heads over the transfer and washing station while the remaining heads are located over polishing stations for wafer polishing so that loading and unloading of wafers and washing of wafers and wafer heads can be performed concurrently with wafer polishing. A robot positioned to the side of the polishing apparatus automatically moves cassettes filled with wafers into a holding tub, and transfers individual wafers vertically held in the cassettes between the holding tub and the transfer and washing station. The transfer and washing station operates to not only transfer the wafers between the robot and the polishing heads, but also to wash the wafer and the polishing heads, for example, by liquid nozzles locate to the side of the station.
摘要:
In one aspect, an apparatus and a method for use in substrate polishing are described wherein a conditioner head is provided for receiving an end effector for conditioning a polishing pad surface; the conditioner head is supported above the polishing pad surface to be conditioned; and the conditioner head is driven with an actuating force from a position that lies along a line that is substantially normal to the polishing pad surface to be conditioned so that an end effector attached to the conditioner head can condition the surface of the polishing pad. In another aspect, pneumatic pressure is supplied through the conditioner head support arm to apply actuating force to the conditioner head so that an end effector attached to the conditioner head can condition the surface of the polishing pad. In yet another aspect, the conditioner head support arm has a fluid channel extending therein and a fluid port, wherein the fluid channel is constructed to receive rinsing fluid and fluid port is constructed to direct rinsing fluid from the fluid channel toward the polishing pad surface to be conditioned.

A method and arrangement for lifting lowering and centering a substrate on a surface employs lift pins have conical tips. A capture range is provided by the conical tips to capture and center misaligned wafers. One or more of the pins are inclined in certain embodiments to enhance the alignment capability of the lift pins. The inclined lift pins, when retracting into a support member at an angle, move a supported substrate horizontally into proper alignment.
