Abstract:
1. A substrate processing system, comprising: a first load lock; a process chamber having a first opening to allow an exchange of a substrate between the first load lock and the first process chamber, wherein the first load lock is fixed to the process chamber throughout operation; first rollers in the process chamber; second rollers in the first load lock; a first transport mechanism configured to move the second rollers in translational movements relative to the first load lock, wherein the first rollers and the second rollers are configured to transport a substrate thereon through the first opening between the first load lock and the process chamber, wherein the first rollers and the second rollers are idler rollers; and wherein at least one of the first load lock and the process chamber is configured to tilt to a first tilt angle to allow the substrate to move under gravitation on the first rollers and the second rollers from the first load lock to the process chamber, and wherein at least one of the first load lock and the process chamber is configured to tilt to a second tilt angle to allow the substrate to move under gravitation on the first rollers and the second rollers from the process chamber to the first load lock.
