Abstract

A pedestal for a thermal treatment chamber is disclosed that includes a body consisting of an optically transparent material. The body includes a first plate with a perforated surface having a plurality of nozzles formed therein, a first portion of the plurality nozzles formed in the body at an angle that is orthogonal to a plane of the first plate, a second portion of the plurality of nozzles formed in the body in an azimuthal orientation and at an acute angle relative to the plane of the first plate, and a third portion of the plurality nozzles formed in the body in a radial orientation and at an acute angle relative to the plane of the first plate.

Claims (26)

1. A pedestal for a thermal treatment chamber, the pedestal comprising:

a body consisting of an optically transparent material and having a geometric center, wherein the body includes:

a first plate with a perforated surface having a plurality of nozzles formed therein, a first portion of the plurality of nozzles formed in the body at an angle that is orthogonal to a plane of the first plate, a second portion of the plurality of nozzles formed in the body in an azimuthal orientation and at an acute angle relative to the plane of the first plate, and a third portion of the plurality of nozzles formed in the body in a radial orientation and at an acute angle relative to the plane of the first plate, wherein the azimuthal orientation is perpendicular to the radial orientation, and wherein the third portion of the plurality of nozzles includes a first nozzle adapted to flow a fluid radially inward across the perforated surface towards the geometric center and a second nozzle adapted to flow a fluid radially outward across the perforated surface away from the geometric center.

2. The pedestal of claim 1 , wherein the body is coupled to a plurality of flexible conduits adapted to couple to a fluid supply.

3. The pedestal of claim 2 , wherein each of the plurality of flexible conduits comprise a metal hose.

4. The pedestal of claim 1 , wherein the body is coupled to one or more lift pins.

5. The pedestal of claim 4 , wherein at least one of the lift pins includes a plurality of conduits formed therein, each of the conduits adapted to couple to a fluid supply.

6. The pedestal of claim 1 , wherein the body comprises a second plate coupled to the first plate, the second plate including a first plurality of radially oriented channels that are in fluid communication with a portion of the plurality of nozzles formed in the first plate.

7. The pedestal of claim 1 , wherein the plurality of nozzles are formed in concentric circles on the first plate.

8. The pedestal of claim 1 , wherein the second portion of the plurality of nozzles includes a first nozzle adapted to flow a fluid in a first direction and a second nozzle adapted to flow a fluid in a second direction that is opposite to the first direction.

9. A pedestal for a thermal treatment chamber, the pedestal comprising:

a body consisting of an optically transparent material and having a geometric center, wherein the body includes:

a first plate with a perforated surface having a plurality of nozzles formed therein, a first portion of the plurality of nozzles formed in the body at an angle that is orthogonal to a plane of the first plate, a second portion of the plurality of nozzles formed in the body in an azimuthal orientation and at an acute angle relative to the plane of the first plate, and a third portion of the plurality of nozzles formed in the body in a radial orientation and at an acute angle relative to the plane of the first plate, wherein the azimuthal orientation is perpendicular to the radial orientation, and wherein the third portion of the plurality of nozzles includes a first nozzle adapted to flow a fluid radially inward across the perforated surface towards the geometric center and a second nozzle adapted to flow a fluid radially outward across the perforated surface away from the geometric center; and

a second plate coupled to the first plate, the second plate including a first plurality of radially oriented channels that are in fluid communication with a portion of the plurality of nozzles formed in the first plate.

10. The pedestal of claim 9 , wherein the second portion of the plurality of nozzles includes a first nozzle adapted to flow a fluid in a first direction and a second nozzle adapted to flow a fluid in a second direction that is opposite to the first direction.

11. The pedestal of claim 9 , wherein the body is coupled to a plurality of flexible conduits adapted to couple to a fluid supply.

12. The pedestal of claim 11 , wherein each of the plurality of flexible conduits comprises a metal hose.

13. The pedestal of claim 9 , wherein the body is coupled to one or more lift pins.

14. The pedestal of claim 13 , wherein at least one of the lift pins includes a plurality of conduits formed therein, each of the conduits adapted to couple to a fluid supply.

15. A pedestal for a thermal treatment chamber, the pedestal comprising:

a body consisting of an optically transparent material and having a geometric center, wherein the body includes:

a first plate with a perforated surface having a plurality of nozzles formed therein in concentric circles, a first portion of the plurality of nozzles formed in the body at an angle that is orthogonal to a plane of the first plate, a second portion of the plurality of nozzles formed in the body in an azimuthal orientation and at an acute angle relative to the plane of the first plate, and a third portion of the plurality of nozzles formed in the body in a radial orientation and at an acute angle relative to the plane of the first plate, wherein the azimuthal orientation is perpendicular to the radial orientation, and wherein the third portion of the plurality of nozzles includes a first nozzle adapted to flow a fluid radially inward across the perforated surface towards the geometric center and a second nozzle adapted to flow a fluid radially outward across the perforated surface away from the geometric center; and

a second plate coupled to the first plate, the second plate including a first plurality of radially oriented channels that are in fluid communication with a portion of the plurality of nozzles formed in the first plate.

16. The pedestal of claim 15 , wherein the body is coupled to a plurality of metal hoses adapted to couple to a fluid supply.

17. The pedestal of claim 15 , wherein the body is coupled to one or more lift pins.
