In one embodiment, a modular liner assembly for a substrate processing chamber is provided. The modular liner assembly includes a first liner and a second liner, each of the first liner and second liner comprising an annular body sized to be received in a processing volume of a chamber, and at least a third liner comprising a body that extends through the first liner and the second liner, the third liner having a first end disposed in the process volume and a second end disposed outside of the chamber.
1. A modular liner assembly for a substrate processing chamber, comprising:
a first liner comprising an annular body sized to be received in a processing volume of a chamber, the first liner having two recessed portions formed between a cut-out portion formed in the annular body;
a second liner comprising an annular body sized to be received in the processing volume of the chamber, the second liner contacting the first liner; and
at least a third liner comprising a body that extends through the first liner and the second liner, the third liner having a first end disposed in the process volume and a second end disposed outside of the chamber, wherein one of the two recessed portions receives a portion of the third liner.
2. The liner assembly of claim 1 , wherein the third liner comprises a gas distribution manifold.
3. The liner assembly of claim 2 , wherein the gas distribution manifold comprises a plurality of first channels and a plurality of second channels.
4. The liner assembly of claim 3 , wherein the plurality of first channels alternate with the plurality of second channels.
5. The liner assembly of claim 3 , wherein the plurality of first channels provide a flow metric that is different than a flow metric provided by the plurality of second channels.
6. The liner assembly of claim 2 , wherein the gas distribution manifold includes a first plurality of outlets and a second plurality of outlets.
7. The liner assembly of claim 6 , wherein the first plurality of outlets are disposed in a first plane and the second plurality of outlets are disposed in a second plane that is different than the first plane.
8. The liner assembly of claim 6 , wherein the first plurality of outlets are formed in a first surface of the gas distribution manifold, the first surface having a first radius and the second plurality of outlets are formed in a second surface of the gas distribution manifold, the second surface having a second radius that is different than the first radius.
9. The liner assembly of claim 1 , wherein the third liner comprises an exhaust liner.
10. A modular liner assembly for a substrate processing chamber having a process volume, the liner assembly comprising:
a first liner and a second liner contacting the first liner, each of the first liner and second liner comprising an annular body having a plurality of recessed portions formed therein; and
at least a third liner comprising a body that is received in and at least partially contacts a portion of the plurality of recessed portions, wherein the body has a first end disposed in the process volume and a second end disposed outside of the chamber.
11. The liner assembly of claim 10 , wherein the third liner comprises one of a gas distribution manifold, a slit valve liner, or an exhaust insert liner assembly.
12. The liner assembly of claim 11 , wherein the gas distribution manifold comprises a plurality of first channels and a plurality of second channels.
13. The liner assembly of claim 12 , wherein the plurality of first channels alternate with the plurality of second channels.
14. The liner assembly of claim 11 , wherein the gas distribution manifold includes a first plurality of outlets and a second plurality of outlets, wherein the first plurality of outlets are disposed in a first plane and the second plurality of outlets are disposed in a second plane that is different than the first plane.
15. A modular liner assembly for a substrate processing chamber, comprising:
a first liner and a second liner contacting the first liner, each of the first liner and second liner comprising an annular body having a plurality of recessed portions formed therein; and
at least a third liner comprising a body that extends through the first liner and the second liner, the third liner having a first end disposed in the process volume and a second end disposed outside of the chamber, wherein one of the plurality of recessed portions receives a portion of the third liner.
16. The liner assembly of claim 15 , wherein each of the recessed portions of the first liner are formed on a first side of the annular body.
17. The liner assembly of claim 16 , wherein the annular body includes a second side opposing the first side and the second side includes two cut out portions.
18. The liner assembly of claim 16 , wherein the plurality of recessed portions comprises two recessed portions that are spaced at about 180 degrees apart.
19. The liner assembly of claim 17 , wherein the recessed portions are formed between each of the cut out portions.
20. The liner assembly of claim 15 , further comprising a fourth liner that is at least partially received in the other one of the plurality of recessed portions.
