Abstract:
In combination with a semiconductor product tool enclosing a mini-environmental atmosphere and having a load port and a load port table for supporting devices to be coupled to the load port, the load port table having contact members including cinematic coupling pins, a metrology device to be coupled to the load port, the metrology device comprising:a housing preserving an inner atmosphere; a coupling region for connecting said inner atmosphere to the mini-environmental atmosphere and extending from said housing, said housing and said coupling region forming an upper portion supported in a position preventing contact with the contact members of the load port table; a measuring device for measuring a property of a semiconductor product; a transport device; and a support supported by and movable over ground by said transport device, said support supporting said housing and said measuring device, said support dimensioned to cause the metrology device to be self-supporting in a position appropriate for coupling said coupling region to the load port.
