    Abstract: A substrate conveying device and a deposition apparatus are provided. The substrate conveying device includes a transmission shaft, a plurality of conveying rollers, and a plurality of bearings. The conveying rollers are configured to convey a substrate respectively. Each conveying roller is assembled to the transmission shaft via the corresponding bearing. Each bearing includes a stator and a rotator. Each conveying roller is fixed to the corresponding rotator. The stators are fixed to the transmission shaft. A magnetic repulsion force parallel to an axial direction of the transmission shaft exists between the stator and the rotator. The stator drives the rotator to rotate via a friction force generated by the magnetic repulsion force between the stator and the rotator.

    Abstract: A film thickness monitoring system is provided. The film thickness monitoring system includes a source, a valve, and a chamber. The source is configured to provide a deposition material. The valve is connected to the source. The chamber includes a manifold, a quartz crystal microbalance, and a pressure sensor. The manifold is connected to the valve and has at least one first nozzle and at least one second nozzle. The quartz crystal microbalance is disposed opposite to the at least one second nozzle. The deposition material is adapted to be deposited on the quartz crystal microbalance through the at least one second nozzle, and the quartz crystal microbalance includes a shutter facing the at least one second nozzle. The pressure sensor is disposed in the manifold. A method for monitoring a film thickness deposition process is also provided.
