Abstract
Provided is a method and apparatus for moving and exchanging reticles within a vacuum lithographic system with minimum particle generation and outgassing. In an example of the method, a first arm of a rotational exchange device (RED) receives a first baseplate holding a first reticle. A second arm of the RED supports and buffers a second baseplate. The first and second baseplates are located substantially equidistant from an axis of rotation of the RED.
