A substrate protection and transport system and method for transitioning a substrate from atmospheric pressure to vacuum in a lithography tool. The system includes one or more removable substrate transport cassettes that support a substrate. The cassette can include a base portion and top portion, and can include a seal. Each cassette has at least one vent and at least one filter. The system further includes a box having a base and lid. The box holds one or more cassette-substrate arrangements. A storage rack having shelves for holding the box-cassette-substrate arrangement is also provided. Further, an entry-exit module having a loadlock is provided for transitioning the cassette-substrate arrangement from atmospheric pressure to vacuum. The entry-exit module can include a shuttle and/or elevator for transporting the cassette-substrate arrangement. During transitioning, the filter(s) and vent(s) restrict particles within the loadlock from entering the cassette-substrate arrangement and reaching a surface of the substrate.

System and method for reticle protection and transport

A substrate protection and transport system and method for transitioning a substrate from atomospheric pressure to vacuum in a lithography tool. The system includes one or more removable substrate transport cassettes. Each cassette has at least one vent and at least one filter. The system further includes an end effector coupled to a robotic arm to enable the substrate to be positioned within one of the cassettes, thereby forming a cassette-substrate arrangement. The system further includes a box having a base and a lid. The box holds one or more of the cassette-substrate arrangements. In this way, a box-cassette-substrate arrangement is provided. An out of vacuum storage rack having shelves for holding the box-cassette-substrate arrangement is also provided. Still further, an entry-exit module having a loadlock is provided for transitioning the cassette-substrate arrangement from atmospheric pressure to vacuum. To transport the substrate, the substrate is first loaded into a removable substrate transport cassette. Next, the cassette-substrate arrangement is loaded into the box. The box-cassette-substrate arrangement is then transported to a shelf of an out of vacuum storage rack. During further processing, the cassette-substrate arrangement is unloaded from the box-cassette-substrate arrangement. The cassette-substrate arrangement is then loaded into a loadlock where it can be transitioned from atmospheric pressure to vacuum. During transitioning, the filters and vents restrict particles within the loadlock from entering the cassette-substrate arrangement and reaching a surface of the substrate.

A reticle protection and transport system and method for a lithography tool. The system includes an indexer that stores a plurality of reticles and a removable reticle cassette. The removable reticle cassette is comprised of an inner chamber and an outer chamber. The system further includes an end effector coupled to a robotic arm. The end effector engages one of the plurality of reticles to enable the reticle to be positioned within the removable reticle cassette and thereafter transported. The system further includes a seal, coupled to the end effector and the robotic arm. To transport the reticle, the reticle is first loaded onto the end effector. Next, the end effector is used to create an arrangement wherein the reticle is loaded into the removable reticle cassette. Importantly, the reticle and removable reticle cassette do not come into contact with one another. The reticle and removable reticle cassette arrangement is then sealed and transported from the indexer to a mount for performing lithographic exposure. Once lithographic exposure is completed, the arrangement is returned to the indexer and the reticle is withdrawn from the removable reticle cassette.
