VARIABLE LOT SIZE LOAD PORT

摘要

A variable lot size load port assembly includes a tool interface, a port door, an advance plate, and first and second latch keys. The tool interface extends generally in a vertical dimension and has an aperture. The port door has a closed position wherein the port door at least partially occludes the aperture. The advance plate is configured to support a front opening unified pod (FOUP) and translate between a retracted position and an advanced position. The first latch key is disposed on the port door at a first elevation configured to selectively engage a corresponding latch key receptacle of a FOUP having a first selected FOUP capacity and the second latch key is disposed on the port door at a second elevation configured to selectively engage a corresponding latch key receptacle of another FOUP having a second selected FOUP capacity.
