MICROENVIRONMENT FOR FLEXIBLE SUBSTRATES

1 . A substrate container comprising:

a shell defining an opening;

a door configured to selectively seal the opening; and

a cantilevered support tray configured to support a flexible substrate within the shell.

2 . The substrate container of claim 1 , further comprising a support post, wherein the support tray is cantilevered from at least one support post.

3 . The substrate container of claim 2 , further comprising at least one support collar configured to couple the support tray to the at least one support post.

4 . The substrate container of claim 3 , wherein the at least one support collar surrounds the at least one support post.

5 . The substrate container of claim 1 , wherein the support tray comprises a registration ledge configured to contact a rearward edge of a substrate supported by the support tray.

6 . The substrate container of claim 5 , wherein the support tray further comprises a tab feature extending forward from the registration ledge, the tab feature being configured to limit side-to-side movement of a substrate supported by the support tray.

7 . The substrate container of claim 1 , wherein the support tray comprises a pin extending upward from the support tray, the pin being configured to mate with a registration hole of a substrate supported by the support tray.

8 . The substrate container of claim 7 , wherein the pin has a tapered profile near a distal end of the pin. The substrate container of claim 1 , further comprising a retention mechanism coupled to the door, the retention mechanism being configured to prevent movement of a substrate supported by the support tray in a first direction.

9 . The substrate container of claim 1 , further comprising a retention mechanism coupled to the door, the retention mechanism being configured to prevent movement of a substrate supported by the support tray in a first direction.

10 . The substrate container of claim 9 , wherein the retention mechanism is further configured to prevent movement of a substrate supported by the support frame in a second direction, the second direction being perpendicular to the first direction.

11 . A support tray configured to support a substrate within a substrate container, the support tray comprising:

At least one support collar configured to couple the support tray to at least one support post such that the support tray is cantilevered from the at least one support post.

12 . The support tray of claim 11 , wherein the at least one support collar is configured to surround the at least one support post.

13 . The support tray of claim 11 , wherein the support tray comprises a registration ledge configured to contact a rearward edge of a substrate supported by the support tray.

14 . The support tray of claim 13 , wherein the support tray further comprises a tab feature extending forward from the registration ledge, the tab feature being configured to limit side-to-side movement of a substrate supported by the support tray.

15 . The support tray of claim 11 , wherein the support tray comprises a pin extending upward from the support tray, the pin being configured to mate with a registration hole of a substrate supported by the support tray.

16 . The support tray of claim 15 , wherein the pin has a tapered profile near a distal end A method of supporting a substrate within a substrate container including a shell defining an opening and a door configured to selectively seal the opening; the method comprising:

placing the substrate on a cantilevered support tray; and

locating the support tray within the shell.

17 . A method of supporting a substrate within a substrate container including a shell defining an opening and a door configured to selectively seal the opening; the method comprising:

placing the substrate on a cantilevered support tray; and

locating the support tray within the shell.

18 . The method of claim 17 , wherein locating the support tray within the shell includes coupling the support tray to at least one support post such that the support tray is cantilevered from the support post.

19 . The method of claim 17 , wherein the support tray includes a pin extending upward from the support tray, and placing the substrate on the support tray includes causing the pin to mate with a registration hole of the substrate.

20 . An article comprising, a frame assembly for supporting a flexible substrate, the frame assembly having a peripheral frame defining an internal opening, and plurality of latches secured to the peripheral frame, wherein the plurality of latches selectively engages at least a portion of a flexible substrate to secure the flexible substrate to the frame assembly.

21 . An article according to claim 20 , wherein the frame assembly is placed on the cantilevered support tray of claim 1 .

22 . An article according to claim 20 , wherein the frame assembly is placed in a front opening unified pod.

23 . An article according to claim 20 , further comprising a cantilevered spring integrally formed within the frame, wherein the spring is actuated by a cam lobe on the latch.
