Abstract:
1. A substrate processing device in which a substrate is carried into the device from one side of the device and is inverted in the device to be carried out and returned to the same side, the device comprising: a plurality of vacuum processing chambers for administering a process on the substrate therein are longitudinally provided and hermetically connected to each other; a substrate carry system which passes through the vacuum chambers, the substrate carry system includes: a unidirectional outward carry line that extends from a first position at a first side of the device to an inversion position within the device, a unidirectional return carry line from the inversion position to a second position at the first side of the device; and a second unidirectional return carry line from the inversion position to the first side of the device, wherein each of the carry lines has a different path and each of the carry lines passes through a plurality of the vacuum processing chambers.
