Abstract

Embodiments of the present disclosure relate to injectors, liners, process kits, processing chambers, and related methods for gas flow in batch processing operations. In one or more embodiments, the liners facilitate gas flow uniformity in batch processing. In one or more embodiments, a liner includes a plurality of inlet openings on an inlet side, the plurality of inlet openings extending into an outer face of the liner. The plurality of inlet openings include a plurality of first inlet openings that include a first row extending into a first side face, and a second row extending into a second side face. The plurality of inlet openings include a plurality of second inlet openings extending between an inner face and the outer face. The liner includes one or more outlet openings on an outlet side. The outlet side opposes the inlet side. The one or more outlet openings extend into the inner face.

First claim

What is claimed is:

1 . A process kit applicable for disposition in a processing chamber, comprising:
an injector, comprising:
an inner face,
an outer face opposing the inner face,
a plurality of first inject openings extending between the inner face and the outer face, the plurality of first inject openings comprising a first row of the first inject openings and a second row of the first inject openings, and
a plurality of second inject openings extending between the inner face and the outer face, the plurality of second inject openings aligned between the first row and the second row of the first inject openings;
a first liner sized and shaped to be disposed inwardly of the injector, the first liner comprising:
an inner face,
an outer face opposing the inner face of the first liner,
a first side face between the inner face of the first liner and the outer face of the first liner,
a second side face between the inner face of the first liner and the outer face of the first liner, the second side face opposing the first side face,
a plurality of inlet openings on an inlet side of the first liner, the plurality of inlet openings extending into the inner face of the first liner and the second side face, and
one or more outlet openings on an outlet side of the first liner, the outlet side opposing the inlet side, and the one or more outlet openings extending into the inner face of the first liner; and
a second liner sized and shaped to be supported at least partially by the first liner, the second liner comprising:
an inner face,
an outer face opposing the inner face of the second liner,
a first side face between the inner face of the second liner and the outer face of the second liner,
a second side face between the inner face of the second liner and the outer face of the second liner, the second side face of the second liner opposing the first side face of the second liner,
a plurality of inlet openings on an inlet side of the second liner, the plurality of inlet openings of the second liner extending into the outer face of the second liner, and
one or more outlet openings on an outlet side of the second liner, the outlet side of the second liner opposing the inlet side of the second liner, the one or more outlet openings of the second liner extending into the inner face of the second liner.

2 . The process kit of claim 1 , wherein at least one of the plurality of second inject openings of the injector is aligned at least partially between columns of the first inject openings.

3 . The process kit of claim 1 , wherein at least one of the plurality of second inject openings of the injector is aligned circumferentially outwardly of the first inject openings.

4 . The process kit of claim 3 , wherein the first inject openings and the second inject openings each comprise apertures.

5 . The process kit of claim 1 , wherein the one or more outlet openings of the first liner comprise:
a recess section extending into the inner face of the first liner; and a passage section extending into the recess section.

6 . The process kit of claim 5 , wherein the plurality of inlet openings of the first liner comprise recesses.

7 . The process kit of claim 1 , wherein the plurality of inlet openings of the second liner comprise:
a first row extending into the first side face of the second liner and configured to align with the first row of the first inject openings of the injector, and a second row extending into the second side face of the second liner and configured to align with the second row of the first inject openings of the injector.

8 . The process kit of claim 7 , wherein the plurality of inlet openings of the second liner comprise:
a plurality of first inlet openings that include the first row and the second row of the second liner; and a plurality of second inlet openings extending between the inner face of the second liner and the outer face of the second liner, the plurality of second inlet openings of the second liner configured to align with the second inject openings of the injector.

9 . The process kit of claim 8 , wherein the first row of the plurality of first inlet openings of the second liner comprise first recesses extending into the outer face and the first side face of the second liner, and the second row of the plurality of first inlet openings of the second liner comprise second recesses extending into the outer face and the second side face of the second liner.

10 . The process kit of claim 9 , wherein the one or more outlet openings of the second liner comprise:
a passage section extending between the first side face and the second side face of the second liner; and an aperture section extending between the inner face of the second liner and the passage section of the second liner.

11 . The process kit of claim 1 , further comprising a third liner sized and shaped to be supported at least partially by the second liner, the third liner comprising:
an inner face; an outer face opposing the inner face of the third liner; a first side face between the inner face of the third liner and the outer face of the third liner; a second side face between the inner face of the third liner and the outer face of the third liner, the second side face opposing the first side face of the third liner, wherein the second side face of the third liner comprises a tapered section; a plurality of inlet openings on an inlet side of the third liner, the plurality of inlet openings of the third liner extending into the first side face of the third liner; and one or more outlet openings on an outlet side of the third liner, the outlet side of the third liner opposing the inlet side of the third liner, the one or more outlet openings of the third liner extending into the inner face of the third liner.

12 . The process kit of claim 11 , wherein the plurality of inlet openings of the third liner extend into the inner face of the third liner, and the one or more outlet openings of the third liner extend into the first side face of the third liner.

13 . The process kit of claim 12 , wherein the plurality of inlet openings of the third liner comprise recesses, and the one or more outlet openings of the third liner comprise a recess section extending into the inner face and the first side face of the third liner.

14 . The process kit of claim 13 , wherein the third liner further comprises one or more second inlet openings extending between the first side face and the tapered section of the second side face, and the one or more outlet openings of the third liner further comprise a passage section extending between the recess section and the tapered section.
