Abstract

According to various embodiments, a frame cassette may include: a housing; a mounting structure inserted in the housing, the mounting structure including a plurality of tape-frame slots, wherein each tape-frame slot is configured to receive a tape-frame, wherein the housing includes an opening to introduce a tape-frame into a tape-frame slot of the plurality of tape-frame slots or to remove a tape-frame from a tape-frame slot of the plurality of tape-frame slots, and a door mounted at the housing, wherein the door is configured to close the opening of the housing to seal the interior of the housing from the exterior of the housing.

Claims (36)

1. A processing arrangement comprising:

a frame cassette comprising:

a housing;

a mounting structure within the housing, the mounting structure comprising a plurality of tape-frame slots, each tape-frame slot configured to receive a tape-frame;

wherein the housing comprises an opening to introduce at least one tape-frame into the at least one tape-frame slot of the plurality of tape-frame slots or to remove the at least one tape-frame from the at least one tape-frame slot of the plurality of tape-frame slots;

a door mounted at the housing,

wherein the door is configured to close the opening of the housing to seal an interior of the housing from an exterior of the housing and to be operated by an overhead transportation system; wherein the housing comprises an electrostatic discharge protection; and

the overhead transportation system configured to transport the frame cassette and to operate the door of the frame cassette.

2. The processing arrangement of claim 1 , wherein the frame cassette further comprises the at least one tape-frame disposed within the at last one tape-frame slot of the plurality of tape-frame slots.

3. The processing arrangement according to claim 1 , wherein the frame cassette further comprises:

a door guidance system mechanically connecting the door to the housing, wherein the door guidance system is configured to guide the door movement.

4. The processing arrangement according to claim 1 , wherein the door comprises a door handling flange, wherein the overhead transportation system is configured to operate the door via the door handling flange.

5. The processing arrangement according to claim 1 , wherein the frame cassette further comprises:

a gasket connected with at least one of the housing or the door, the gasket sealing the housing air-tightly when the door is closed.

6. The processing arrangement according to claim 5 , wherein the gasket completely surrounds the opening in the housing.

7. The processing arrangement according to claim 1 , wherein the frame cassette further comprises:

a transport flange which allows the frame cassette to be transported by the overhead transport system.

8. The processing arrangement according to claim 1 , wherein the door and the housing are configured such that the interior of the housing is hermetically sealed maintaining cleanroom conditions of ISO-class 7 or cleaner than ISO-class 7 according to the ISO-14644-1 dated 1999 cleanroom standard in the interior of the housing.

9. The processing arrangement according to claim 1 , wherein the frame cassette further comprises:

a valve structure to purge the housing with inert gas.

10. The processing arrangement according to claim 1 , wherein the frame cassette further comprises:

one or more RFID-tags for frame cassette identification.

11. The processing arrangement according to claim 1 , further comprising:

a semiconductor processing tool.

12. The processing arrangement according to claim 11 , wherein the frame cassette further comprises:

a kinematic coupling comprising at least one feature to align the frame cassette to a load port of the semiconductor processing tool.

13. The processing arrangement according to claim 11 , further comprising:

a further semiconductor processing tool,

wherein the overhead transportation system is configured to transport the frame cassette from the semiconductor processing tool to the further semiconductor processing tool.

14. The processing arrangement according to claim 1 , wherein the mounting structure comprises 13 or 25 tape-frame slots.

15. The processing arrangement according to claim 1 , wherein the frame cassette further comprises:

a frame restraint preventing hosted tape-frames from slipping within the housing during transportation of the frame cassette.

16. The processing arrangement according to claim 1 , wherein the frame cassette further comprises:

bottom rails for a transport of the frame cassette via roller conveyors.

17. The processing arrangement according to claim 1 , wherein the frame cassette further comprises:

a cassette stacking to stack two or more than two frame cassettes on top of each other.
