摘要:
A stage apparatus for displacing an object having a substantially flat surface is described. The apparatus includes an object table for supporting the object and a positioning device for displacing the object table in a first direction. The apparatus further includes a clamping device for clamping the object to the object table by a first clamping force, the first clamping force being controlled by an electronic control unit based upon a state of the object.

A lithographic apparatus having an improved transfer unit, is presented. The lithographic apparatus includes a processing unit that performs a lithographic process involving exchangeable objects in which the processing unit includes an illumination system that provides a beam of radiation, a support structure configured to support a patterning device that imparts a desired pattern to the beam of radiation, a substrate holder configured to hold a substrate, and a projection system configured to project the patterned beam onto a target portion of the substrate. The lithographic apparatus also includes a transfer unit comprising a single robot. The single robot is configured to transfer a first exchangeable object from a loading station to the processing unit and to transfer a second exchangeable object from the processing unit to a discharge station.

The present invention relates to a lithographic apparatus including a projection system configured to project a patterned radiation beam onto a target portion of a substrate held on a substrate support, the patterned beam of radiation being patterned with a patterning device held by a patterning device support. The lithographic apparatus includes an exchangeable object handling apparatus for exchanging an exchangeable object with a exchangeable object station and a support, the exchangeable object being one of the substrate and the patterning device and the support being one of the substrate support and the patterning device support, the exchangeable object handling apparatus including an intermediate holding device for holding an exchangeable object, which intermediate holding device can interact with the support to place an exchangeable object on or take an exchangeable object from the support, and a robot which can exchange an exchangeable object with the support, the intermediate holding device and said exchangeable object station.

The present invention relates to a lithographic projection apparatus with a supporting structure to support and move an object, like a substrate. The supporting structure may be a robot having a robotic arm with a support frame for supporting, e.g. the substrate. The support frame includes a clamping structure having one or more clamps for holding the substrate during movement. The robot arm comprises one or more compliant parts. The clamp may be a Johnson-Raybeck effect type clamp with an oxidized upper surface. For better de-clamping, a RF AC decaying de-clamping voltage may be provided to the clamp. The apparatus may be cleaned with one single substrate only.

The invention relates to a transfer apparatus for transferring an object (W). the transfer apparatus comprises a gripper (15) for at least one of gripping the object (W) at a first position and then releasing the object (W) at a second position proximate to a receiver (20) and releasing the object (W) at a first position after gripping the object at a second position proximate to the receiver (20). The transfer apparatus is further provided with a measurement device (22) arranged to measure the relative position of the gripper (15) with respect to the receiver (20) in at least one dimension. Further, a relative position error is defined with respect to a desired relative position based on the relative position measured. The relative position of the gripper (15) and the receiver (20) are adjusted for minimizing the relative position error in the second position.
