- the arm is fixed in a suspended state, and is delivered to another position by the 120-degree rotation of the arm.
- the load lock chamber 71 opens below the chamber, and loads and unloads non-processed substrates from below.
- the pick-and-place arm 72 is rotated in the direction of the arrow shown in the figure, the film formation is started from the second film formation processing unit 20, and the first film formation processing The latter half of the film forming process is performed in the processing unit 10.
- the substrate on which the film formation processing has been performed is again transported to the first delivery position 31, transported to the load lock chamber 71, and unloaded outside.
- the rotation direction can be selected in any direction in each of the film forming units and the coupling mechanism.
- the load lock mechanism is disposed between the first and second film forming units, the independence of the film forming unit can be increased, and the process can be switched according to the type of the optical disc. Is easier to do.
- the first film forming unit 10 having the load lock mechanism 14C is provided in a branched manner. It is.
- the third film forming unit 80 has a transport rotary table and a film forming chamber, and is connected to the first film forming unit 10 by a connecting unit 81.
- the same parts as those in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted.
- four first film formation chambers (12a to 12d) of the first film formation processing unit 10, one cooling room 13a, and three second film formation chambers of the second film formation processing unit 20 are used.
- the number of the third film forming chambers of the third film forming unit 80 is two (82a, 82b). According to the present embodiment, by allocating the film forming processing units according to the type of the multilayer film to be laminated, precise sputtering control can be performed, the tact can be easily adjusted, and the chamber of the sputtered substance can be easily formed. Internal coating is limited, and maintenance such as cleaning becomes easy.
