It can be arranged away from the edge of the direction to the outside of the substrate tray 18.
- the outside of the substrate tray 18 is covered with a mask 27, and the further away the substrate tray 18, the farther from the inner edge of the mask 27 (the portion where the substrate 1 is exposed with respect to the cathode 23). Therefore, when the side clamp 19 is disposed away from the inner edge of the mask 27 to the outside of the substrate tray 18 during film formation, the side portion is located in the back of the region on the substrate tray 18 covered by the mask 27.
- the clamp 19 will be arranged. Therefore, even if the sputtered particles collide with gas molecules such as Ar and the sputtered particles are incident on the substrate 1 at an angle, the amount of sputtered particles reaching the side clamp 19 can be reduced.
- the substrate 1 when the substrate 1 is transported by the substrate tray 18, the substrate 1 is supported by the side clamps 19 arranged around the region 181. Therefore, for example, when the substrate 1 is transferred to the outside of the sputtering chamber 16 after the film formation is completed, a force opposite to the forces 10 and 11 is applied to the side clamp 19. As a result, the side clamp 19 disposed outside the substrate tray 18 is moved in the direction toward the inside of the substrate tray 18, the side clamp 19 is brought into contact with the substrate 1, and the substrate 1 is moved by the side clamp 19. Hold. In this way, by changing the position of the side clamp 19 between the film formation and the substrate transfer, the region in which the side clamp 19 is covered with the mask 27 during the film formation in which the sputtered particles fly.
- the side clamp 19 can be arranged in the back of the substrate, and the substrate 1 can be firmly held (clamped) by the side clamp 19 when the substrate is transported.
- the substrate 1 is held by the side clamp 19 when the substrate is transported.
- the side clamp 19 is moved from the position holding the substrate 1 to the far side of the region covered with the mask (the substrate tray 18 by the moving mechanism).
- the side clamp 19 is moved to the outside. If the film forming operation is performed in this state, adhesion of the sputtered particles to the side clamp 19 can be reduced.
- the moving mechanism may be a mechanism that interlocks the state of the clamp when the thin film is formed with the attachment of the mask 27. That is, when the side clamp 19 holds the substrate 1, the substrate 1 can be pressed by the spring force connecting the side clamp 19 and the substrate tray 18 in conjunction with the removal of the mask 27.
- FIG. 8 is a diagram illustrating an example of the moving mechanism, and is a diagram for explaining the moving mechanism when the attachment / detachment of the mask 27 and the movement of the side clamp 19 are interlocked.

- the L-shaped jig 34 is rotatably attached to the base 191 by a pin 36b.
- the L-shaped jig 34 is rotatably fixed to each of the bottom portion of the hollow portion 184 and the base portion 191 slidably disposed on the guide portion 35.

- the mask 27 is provided with a bar portion 271.
- the bar portion 271 passes through the through-hole 185 and moves the L-shaped jig 34 in the arrow direction S. Press on.
- the rod portion 271 on the mask 27 pushes the L-shaped jig 34 connected to the side clamp 19 as shown in FIG.
- the side clamp 19 moves away. That is, when the control device drives a mask driving mechanism (not shown) to bring the mask 27 close to the substrate tray 18 installed in the sputtering chamber 16, the rod portion 271 is inserted into the L-shaped jig 34 through the through hole 185. The L-shaped jig 34 is pressed toward the arrow direction S.
- the base 191 moves along the arrow direction R in the arrow direction R while extending the spring 33 in conjunction with the rotation. Move.
- the control device stops the movement of the mask 27 along the arrow direction S, the movement of the rod portion 271 is also stopped, and the movement of the L-shaped jig 34 and the base portion 191 is also stopped. Therefore, at the time of film formation, the base 191 and the clamp 192 can be retracted into the back of the region covered with the mask 27.
- the side clamp 19 holds the substrate 1 (for example, when the substrate 1 is transported), the rod portion 271 associated with the mask 27 is separated, and the force of the spring 33 that connects the side clamp 19 and the substrate tray 18 is separated. Hold the substrate 1. That is, when the control device controls the mask driving mechanism to move the mask 27 away from the substrate tray 18, the bar portion 271 moves in the direction opposite to the arrow direction S, and the bar portion 271 is moved from the L-shaped jig 34. The pressure on the L-shaped jig 34 is released.
- a restoring force acts on the extended spring 33, and the restoring force causes the base portion 191 to move the guide portion 35 on the side opposite to the arrow direction R.
- the base portion 191 and the clamp portion 192 that have been retracted at the time of film formation can be pulled out and the substrate 1 can be supported by the clamp portion 192.
- the substrate 1 can be held by newly attaching a convex portion 183 as a substrate receiver to the substrate tray 18 below the clamp portion 192. Since the substrate tray 18 and the substrate 1 are inclined, the substrate 1 does not fall down as described above.

- an electromagnetic drive mechanism for example, a drive mechanism such as an actuator is provided and the drive mechanism is controlled by a control device
- a discharge start signal or gas A mechanism that can be interlocked via an introduction signal and an electrical signal may be used.
- the movement (slide) distance of the side clamp 19 that prevents the film from being deposited by sputtering varies depending on the sputtering power, gas pressure, and the distance between the mask and the glass substrate. It is also possible to select arbitrarily according to these conditions.
- the voltage and gas on the cathode 23 side are stopped, and at the same time, the mask 27 is separated from the substrate tray 18 and the side clamp 19 holds the substrate 1 again.
