Robot magazine and tray load and unload system

A wafer loading system for transferring wafer boats stored in an associated wafer magazine, the wafer loading system comprising:

• a wafer magazine jig;
• a load port having a wafer magazine seat configured to seat the associated wafer magazine and a wafer magazine jig seat configured to seat the wafer magazine jig;
• a bidirectional push bar arranged to push wafer boats between the associated wafer magazine seated in the wafer magazine seat and the wafer magazine jig seated in the wafer magazine jig seat;
• and
• a boat bridge disposed in a gap between the wafer magazine seat and the wafer magazine jig seat and configured to support wafer boats being pushed between the associated wafer magazine seated in the wafer magazine seat and the wafer magazine jig seated in the wafer magazine jig seat.

A wafer transfer method for transferring wafers, the method comprising:

• disposing a wafer magazine on a load port, the wafer magazine containing wafer boats with semiconductor wafers;
• pushing the wafer boats out of the wafer magazine and into a wafer magazine jig disposed on the load port;
• and
• during the pushing, supporting the wafer boats as the wafer boats pass across a gap between the wafer magazine and the wafer magazine jig using a boat bridge.
