Abstract

In one embodiment, a chamber is provided that includes a chamber body and a lid defining an interior volume, a frame within the interior volume, the frame sized to receive a plurality of substrates in a first orientation, and a rotational drive assembly coupled to the frame for rotating the frame and flipping each of the plurality of substrates to a second orientation that is different than the first orientation.

Claims

1. A chamber, comprising:

a chamber body and a lid defining an interior volume;

a frame within the interior volume, the frame sized to receive a plurality of substrates in a first orientation; and

a rotational drive assembly coupled to the frame for rotating the frame and flipping each of the plurality of substrates to a second orientation that is different than the first orientation.

2. The chamber of claim 1, wherein the plurality of substrates are supported by a first carrier that is transferred to the frame.

3. The chamber of claim 2, wherein the plurality of substrates are exchanged to a second carrier in the second orientation.

4. The chamber of claim 3, further comprising a lift plate that selectively contacts one or both of the first carrier and the second carrier.

5. The chamber of claim 1, wherein the plurality of substrates are supported by a first carrier that is transferred to an inner perimeter of the frame.

6. The chamber of claim 5, wherein a second carrier is positioned over the first carrier and the first carrier and the second carrier are received in the inner perimeter of the frame.

7. The chamber of claim 6, wherein the frame includes a plurality of clamps that contact both of the first carrier and the second carrier.

8. The chamber of claim 1, wherein the rotational drive assembly rotates the frame 180 degrees during movement between the first orientation and the second orientation.

9. A chamber, comprising:

a chamber body and a lid defining an interior volume;

a frame within the interior volume, the frame sized to receive a first carrier having a plurality of substrates disposed in the first carrier in a face-up orientation;

a second carrier disposable over the first carrier; and

a rotational drive assembly coupled to the frame for rotating the first carrier and the second carrier.

10. The chamber of claim 9, further comprising a lift plate that selectively contacts one of the first carrier or the second carrier.

11. The chamber of claim 10, wherein the first carrier includes openings formed therethrough sized to receive a plurality of lift pins coupled to the lift plate.

12. The chamber of claim 9, further comprising a plurality of clamps coupled to an inner perimeter of the frame.

13. The chamber of claim 12, wherein each of the plurality of clamps are biased inwardly.

14. The chamber of claim 12, further comprising an actuator coupled to each of the plurality of clamps.

15. The chamber of claim 9, further comprising a stabilizer assembly adapted to secure the first carrier and the second carrier within the frame.

16. A method for transferring a plurality of substrates, comprising:

transferring a first carrier to a frame structure within a chamber, wherein the first carrier includes a plurality of substrates disposed in a face-up orientation;

transferring a second carrier to the frame structure in a position adjacent to the first carrier; and

rotating the frame structure to move the plurality of substrates to the second carrier.

17. The method of claim 16, wherein, after the rotating, the plurality of substrates are disposed in the second carrier in a face-down orientation.

18. The method of claim 16, further comprising transferring the first carrier out of the frame.

19. The method of claim 16, further comprising transferring the second carrier and the plurality of substrates out of the frame.

20. The method of claim 19, depositing a dopant on exposed surfaces of the substrates in the second carrier.
