Abstract

A substrate processing apparatus includes a first chamber, a second chamber provided adjacent the first chamber to form a process space therebetween, a support unit supporting the second chamber with a gap between the first and second chambers, and a vacuum unit to place the process space in a vacuum state, the process spaced sealed in the vacuum state.

Claims

1. A substrate processing apparatus, comprising:

a first chamber;

a second chamber provided adjacent the first chamber to form a process space therebetween;

a support unit supporting the second chamber with a gap between the first and second chambers; and

a vacuum unit to place the process space in a vacuum state, the process spaced sealed in the vacuum state.

2. The apparatus of claim 1, further comprising:

a sealing member provided in the gap between the first and second chambers to close the gap during the vacuum state.

3. The apparatus of claim 1, wherein the support unit comprises:

a support shaft, having a first end coupled to the second chamber, to support the second chamber; and

a first plate connected to a second end of the support shaft, wherein the support shaft is made of an elastic material.

4. The apparatus of claim 3, wherein the support unit further comprises:

a second plate adjacent the first plate; and

a connection member that connects the first and second plates to each other and restricts the first plate to allow the first plate to move relative to the second plate.

5. The apparatus of claim 4, further comprising an elastic member provided between the first and second plates.

6. The apparatus of claim 3, further comprising:

a plunger inserted into a first surface of the second chamber adjacent to a second surface of the first chamber, the plunger comprising a support body projecting from the first surface of the second chamber.

7. The apparatus of claim 1, wherein the support unit further comprises:

a horizontal moving member that moves the second chamber horizontally relative to the first chamber along one direction, wherein the first surface of the second chamber and the second surface of the first chamber face each other and are inclined in parallel with each other along the one direction.

8. The apparatus of claim 7, further comprising:

a plunger inserted into the first surface of the second chamber adjacent to the second surface of the first chamber, the plunger comprising a support body aligning a position of the second chamber moving toward the first chamber, the support body projecting from the first surface of the second chamber.

9. The apparatus of claim 7, wherein the support unit further comprises a rotation member to make the first surface of the second chamber face upward by rotating the second chamber.

10. The apparatus of claim 1, wherein the support unit comprises a support shaft having a first end connected to the second chamber to support the second chamber.

11. The apparatus of claim 10, wherein the support unit further comprises:

a first plate connected to a second end of the support shaft;

a second plate provided adjacent the first plate; and

an elastic member provided between the first and second plates.

12. The apparatus of claim 10, further comprising:

a sealing member provided in the gap between the first and second chambers to close the gap during the vacuum state.

13. The apparatus of claim 10, further comprising:

a plunger inserted into a first surface of the second chamber adjacent to a second surface of the first chamber, the plunger comprising a support body projecting from the first surface of the second chamber to support the second chamber.

14. The apparatus of claim 10, wherein the support unit further comprises a horizontal moving member that moves the second chamber horizontally relative to the first chamber along one direction,

wherein the first surface of the second chamber and the second surface of the first chamber face each other and are inclined in parallel with each other along the one direction.

15. The apparatus of claim 14, further comprising:

a plunger inserted into the first surface of the second chamber adjacent to the second surface of the first chamber, the plunger comprising a support body aligning a position of the second chamber moving toward the first chamber and projecting from the first surface of the second chamber.

16. The apparatus of claim 14, further comprising a rotation member to make the first surface of the second chamber face upward by rotating the second chamber.

17. A method of opening/closing a process space in a substrate processing apparatus having first and second chambers, comprising:

providing the second chamber over the first chamber to form a gap therebetween; and

closing a process space after the process space formed inside the first and second chambers is kept in a vacuum state.

18. The method of claim 17, wherein the process space is closed during the vacuum state using a sealing member that is provided in the gap between the first and second chambers.

19. The method of claim 17, wherein the process space is opened by venting the vacuum.
