Abstract:
A method for making an exposure apparatus which exposes a pattern of a mask onto an object, the method comprising the steps of:providing an exposure device between said mask and said object, the exposure device exposes the pattern of the mask onto the object;providing a movable mask stage that holds the mask;providing a movable object stage that holds the object;providing a reaction frame dynamically isolated from the exposure device;providing a drive to move the mask stage and the object stage such that a reaction force caused by movement of the mask stage and the object stage is transferred substantially to the reaction frame;providing a first position detector, dynamically isolated from the reaction frame, to detect a position of the mask stage; andproviding a second position detector, dynamically isolated from the reaction frame, to detect a position of the object stage.
