Abstract:
A method of film deposition in an apparatus having a plurality of vacuum chambers including a loading chamber, an unloading chamber, at least one processing chamber and at least one rotation chamber and a continuous looped line transfer path extending through the plurality of vacuum chambers, the method comprising the steps of:loading a substrate on a carrier in the loading chamber;transferring the carrier and the substrate along the continuous looped line transfer path through the plurality of vacuum chambers such that the substrate and carrier pass only once through each of the vacuum chambers, and the substrate and carrier do not travel in reverse direction of travel throughout the rotation chamber;depositing a film on the substrate in the processing chamber;changing a direction of transfer of the carrier and the substrate in the rotation chamber with a rotation mechanism; andunloading the substrate in the unloading chamber.
