In the wafer factory corridor, the top Automatic Transportation System AMHS is transporting wafers at a speed of 13 kilometers per hour between various manufacturing stages without stopping for 24 hours. Each vehicle is mounted in a FOUP front-end opening film box), where up to 25 300mm wafers can be loaded.

 

All the holes on the plant Floor ensure that the air is circulated from top to bottom, and dust may be minimized.

 

The FOUP film box is attached to a manufacturing device, and the latter is being lifted by AMHS.

 

 

Almost all manufacturing processes are completed automatically, so the work of most workers in the plant is to ensure the normal operation of these equipment.
