Abstract

A gas supply member includes a first side opposite a second side and an inner surface defining a first opening extending between the first and second sides. The gas supply member includes a third side orthogonal to the first side, the third side includes a first extension that has a face partially defining the second side, and the first extension includes a first plurality of holes extending through the first extension to the face. The gas supply member includes a fourth side opposite the third side, the fourth side includes a protrusion that has a face partially defining the second side. The gas supply member also includes a baffle disposed adjacent to the inner surface, the baffle includes a first portion extending from the inner surface and a second portion attached to the first portion, and the second portion orthogonal to the first portion and parallel to the third side.

Claims (47)

1. A gas supply member, comprising:

a first side;

a second side opposite the first side;

an inner surface defining a first opening, the first opening extending between the first side and the second side;

a third side orthogonal to the first side, the third side comprising:

a first extension having a face partially defining the second side and comprising a first plurality of holes extending through the first extension to the face;

a fourth side opposite the third side, the fourth side comprising:

a protrusion, the protrusion having a face partially defining the second side;

a baffle disposed adjacent to the inner surface, the baffle comprising:

a first portion extending from the inner surface; and

a second portion attached to the first portion, the second portion orthogonal to the first portion and parallel to the third side;

a recess formed in the fourth side and between the first side and the second side, the recess is centrally located on the fourth side and extends toward the first opening; and

a vertical slit formed within the first side and extending from the recess to the first opening, the vertical slit is perpendicular to the fourth side.

2. The gas supply member of claim 1 , further comprising a first angular surface extending from the third side to below the first opening partially defining the second side.

3. The gas supply member of claim 2 , further comprising a second angular surface extending from the face of the protrusion towards the first opening partially defining the second side.

4. The gas supply member of claim 3 , further comprising a connecting surface between the first angular surface and the second angular surface.

5. The gas supply member of claim 3 , wherein the recess comprises a first rounded corner and a second rounded corner.

6. The gas supply member of claim 3 , wherein each of the first plurality of holes extends through the first angular surface.

7. The gas supply member of claim 1 , wherein the protrusion has a second plurality of holes extending to the second side.

8. The gas supply member of claim 1 , further comprising:

a depression formed within the third side and extending adjacent to and along the length of the first extension; and

an elongated recess formed within the depression.

9. The gas supply member of claim 8 , further comprising a second plurality of holes formed within the elongated recess and extending between the elongated recess and the first opening, the second plurality of holes is in fluid communication with the baffle.

10. A gas supply member comprising:

a first side;

a second side opposite the first side;

an inner surface defining a first opening, the first opening extending between the first side and the second side;

a third side orthogonal to the first side, the third side comprising:

a first extension having a face partially defining the second side and comprising a first plurality of holes extending through the first extension to the face;

a fourth side opposite the third side, the fourth side comprising:

a protrusion, the protrusion having a face partially defining the second side; and

a baffle disposed adjacent to the inner surface, the baffle comprising:

a first portion extending from the inner surface;

a second portion attached to the first portion, the second portion orthogonal to the first portion and parallel to the third side;

a cavity formed between the first portion and the first side;

a depression formed within the third side and extending adjacent to and along the length of the first extension;

an elongated recess formed within the depression; and

a second plurality of holes formed within the elongated recess and extending between the elongated recess and the first opening, the second plurality of holes is in fluid communication with the baffle.

11. The gas supply member of claim 10 , further comprising a lip disposed on the second portion.

12. The gas supply member of claim 10 , wherein the recess comprises a first rounded corner and a second rounded corner.

13. The gas supply member of claim 11 , further comprising a first angular surface extending from the third side to below the first opening partially defining the second side.

14. The gas supply member of claim 13 , further comprising a second angular surface extending from the face of the protrusion towards the first opening partially defining the second side.

15. The gas supply member of claim 14 , further comprising a connecting surface, wherein the connecting surface is between the first angular surface and the second angular surface.

16. The gas supply member of claim 14 , wherein each of the first plurality of holes extend through the first angular surface.

17. The gas supply member of claim 10 , further comprising:

a recess formed in the fourth side and between the first side and the second side, the recess is centrally located on the fourth side and extends toward the first opening; and

a vertical slit formed within the first side and extending from the recess to the first opening, the vertical slit is perpendicular to the fourth side.
