2. The system of claim 1 , wherein the warehouse apparatus is configured to interface with the semiconductor processing unit through the at least one load/unload port, and to interface with the AMHS vehicle through the at least one input port and the at least one output port.

3. The system of claim 1 , wherein the warehouse apparatus is further configured to perform one of the following: transporting the plurality of tray cassette containers from the at least one input port to the at least one output port, and sorting the at least one second tray in the at least one tray cassette.

4. The system of claim 3 , wherein the second tray is one of the following: an empty first tray and the first tray with a plurality of semiconductor dies.

5. The system of claim 1 , further comprising a computer control system.

6. The system of claim 1 , wherein the warehouse apparatus further comprises a tray cassette robotic arm, wherein the tray cassette robotic arm is configured to transport the at least one tray cassette in each of the plurality of tray cassette containers between the load/unload port and at least one of the following: the input port and the output port.

7. The system of claim 1 , wherein the warehouse apparatus is configured to transport the at least one tray cassette from the load/unload port to the at least one output port, placing the at least one tray on the plurality of tray cassette containers, and loading the plurality of tray cassette containers on the AMHS vehicle.

8. A system, comprising:
a semiconductor processing unit,
an Automated Materials Handling System (AMHS) vehicle, and
a warehouse apparatus,
wherein the warehouse apparatus comprises at least one input port, at least one output port, and at least one load/unload port, wherein the warehouse apparatus is configured to perform: receiving a plurality of tray cassette containers from the AMHS vehicle at the at least one input port, transporting at least one tray cassette in each of the plurality of tray cassette containers from the at least one input port along a Z direction, then a X-direction to an exchange zone directly right below the at least one load/unload port transporting the at least one tray cassette from the exchange zone to the at least one load/unload port along the Z direction, transporting at least one first tray from the at least one tray cassette along a Y direction to the semiconductor processing unit via a tray feeder conveyor, wherein the tray feeder conveyor is connected to the at least one load/unload port, and receiving at least one second tray from the semiconductor processing unit via the tray feeder conveyor, wherein the warehouse apparatus is configured to interface with the semiconductor processing unit through the at least one load/unload port, and to interface with the AMHS vehicle through the at least one input port and the at least one output port.

9. The system of claim 8 , wherein the warehouse apparatus is further configured to perform one of the following: transporting the plurality of tray cassette containers from the at least one input port to the at least one output port, and sorting the at least one second tray in the at least one tray cassette.

10. The system of claim 9 , wherein the second tray is one of the following: an empty first tray and the first tray with a plurality of semiconductor dies.

11. The system of claim 8 , further comprising:
a computer control system.

12. The system of claim 8 , wherein the warehouse apparatus further comprises a tray cassette robotic arm, wherein the tray cassette robotic arm is configured to transport the at least one tray cassette in each of the plurality of tray cassette containers between the load/unload port and at least one of the following: the input port and the output port.

13. The system of claim 8 , wherein the warehouse apparatus is configured to transport the at least one tray cassette from the load/unload port to the at least one output port, placing the at least one tray on the plurality of tray cassette containers, and loading the plurality of tray cassette containers on the AMHS vehicle.

14. A method, comprising:
receiving a plurality of tray cassette containers from an automatic material handling system (AMHS) vehicle at an input port of a warehouse apparatus;
transporting at least one tray cassette in each of the plurality of tray cassette containers from at least one input port of the warehouse apparatus along a Z direction, then a X-direction to an exchange zone directly right below a load/unload port of the warehouse apparatus;
transporting the at least one tray cassette from the exchange zone to the load/unload port along the Z direction,
transporting a first tray from the at least one tray cassette along a Y direction to a semiconductor processing unit via a tray feeder conveyor, wherein the tray feeder conveyor is connected to the load/unload port; and
receiving at least one second tray from the semiconductor processing unit via the tray feeder conveyor.

15. The method of claim 14 further comprising:
