Abstract

A load port system includes an isolation compartment coupled to an equipment front end module (EFEM). Reactive gas is to be removed from the isolation compartment. The load port system further includes an elevator disposed in the isolation compartment. The elevator is coupled to an elevator arm that extends from the isolation compartment into the EFEM through an opening to raise and lower a carrier opener within the EFEM.

Claims (34)

1. A load port system comprising:

an isolation compartment coupled to an equipment front end module (EFEM), wherein reactive gas is to be removed from the isolation compartment; and

an elevator disposed in the isolation compartment, wherein the elevator is coupled to an elevator arm that extends from the isolation compartment into the EFEM through an opening to raise and lower a carrier opener within the EFEM, wherein the elevator arm comprises a first portion that extends from the isolation compartment into the EFEM through the opening and a second portion that extends from the first portion within the EFEM, the first portion and the second portion being substantially perpendicular to each other.

2. The load port system of claim 1 , wherein the reactive gas is to be removed from the isolation compartment via a non-reactive purge gas provided into the isolation compartment.

3. The load port system of claim 1 further comprising:

a non-reactive purge gas supply disposed in the isolation compartment, wherein the non-reactive purge gas supply is configured to remove the reactive gas from the isolation compartment.

4. The load port system of claim 1 further comprising:

a fan disposed in the isolation compartment, wherein the fan is configured to remove the reactive gas from the isolation compartment.

5. The load port system of claim 1 , wherein a fan is disposed in the EFEM, wherein the fan is configured to remove the reactive gas from the isolation compartment.

6. The load port system of claim 1 further comprising:

a vent comprising a one-way check valve to allow the reactive gas out of the isolation compartment.

7. The load port system of claim 1 , wherein a first volume of the isolation compartment is partially isolated from a second volume of the EFEM, and wherein the isolation compartment is in fluid communication with the EFEM via the opening.

8. An isolation compartment system comprising:

a housing partially enclosing an interior volume, the housing forming an opening, wherein the housing is configured to couple to an equipment front end module (EFEM), and wherein reactive gas is to be removed from the housing; and

an elevator system disposed at least partially in the interior volume, wherein the elevator system comprises an elevator arm that is configured to couple to a carrier opener via the opening to raise and lower the carrier opener within the EFEM, wherein the elevator arm comprises a first portion that extends into the EFEM through the opening and a second portion that extends from the first portion within the EFEM, the first portion and the second portion being substantially perpendicular to each other.

9. The isolation compartment system of claim 8 , wherein the elevator system comprises:

an elevator disposed in the interior volume; and

the elevator arm coupled to the elevator, wherein the elevator arm is configured to extend from the housing into the EFEM through the opening to raise and lower the carrier opener within the EFEM.

10. The isolation compartment system of claim 8 , wherein the reactive gas is to be removed from the housing via a non-reactive purge gas provided into the housing.

11. The isolation compartment system of claim 8 , wherein a non-reactive purge gas supply is disposed in the housing, and wherein the non-reactive purge gas supply is configured to remove the reactive gas from the housing.

12. The isolation compartment system of claim 8 , wherein a fan is disposed in the housing, wherein the fan is configured to remove the reactive gas from the housing.

13. The isolation compartment system of claim 8 , wherein a fan is disposed in the EFEM, wherein the fan is configured to remove the reactive gas from the housing.

14. The isolation compartment system of claim 8 further comprising:

a vent comprising a one-way check valve configured to allow the reactive gas out of the housing.

15. A system comprising

a memory; and

a processor coupled to the memory, the processor configured to:

cause reactive gas to be removed from an isolation compartment housing coupled to an equipment front end module (EFEM); and

actuate an elevator disposed in the isolation compartment housing, wherein the elevator is coupled to an elevator arm that extends from the isolation compartment housing into the EFEM through an opening to raise and lower a carrier opener within the EFEM, wherein the elevator arm comprises a first portion that extends from the isolation compartment into the EFEM through the opening and a second portion that extends from the first portion within the EFEM, the first portion and the second portion being substantially perpendicular to each other.

16. The system of claim 15 , wherein the processor is disposed in the isolation compartment housing.

17. The system of claim 15 , wherein the reactive gas is to be removed from the isolation compartment housing via a non-reactive purge gas provided into the isolation compartment housing.

18. The system of claim 15 , wherein a non-reactive purge gas supply is disposed in the isolation compartment housing, and wherein the non-reactive purge gas supply is configured to remove the reactive gas from the isolation compartment housing.

19. The system of claim 15 , wherein a fan is disposed in the isolation compartment housing or in the EFEM, wherein the fan is configured to remove the reactive gas from the isolation compartment housing.

20. The system of claim 15 , wherein a vent comprising a one-way check valve is configured to allow the reactive gas out of the isolation compartment housing.
