Abstract: A reticle inspection and purging method comprises following steps. A first reticle is moved from a first load port of a lithography tool to a reticle inspection tool located outside the lithography tool. The first reticle is inspected using the reticle inspection tool located outside the lithography tool. Whether the first reticle is acceptable for exposure is determined based on the inspection result. In response the determination determines that the first reticle is not acceptable for exposure, the first reticle is purged.

Abstract: A ground simulation device and method for an on-orbit manipulation of a space manipulator is provided. The ground simulation device includes: a dual-arm robot, configured to simulate the space manipulator operating a target object; a suspension device, including a fixed post and passive rods, where the passive rods are movably connected with a top end of the fixed post, and the target object is suspended to the passive rods; and a simulation platform, configured to fix the dual-arm robot and the suspension device thereon. The ground simulation device provides the passive rods on the suspension device and suspends the target object to the passive rods, thus overcoming the gravity of the target object. In addition, the passive rods can drive the target object to move under an influence of an external force, achieving a similar suspension effect to that in space, and providing a desired, safe, and reliable implementation effect.
