A measurement device (1), i.e. a metrology tool, and a vehicle (2) are combined to provide a mobile metrology in a fabrication facility. Peripheral equipment such as a device transfer unit (3), for , e.g., FOUPs in semiconductor manufacturing, an electronic control system (5) with, e.g., a PC, monitor and keyboard and optionally a vacuum pump (9) is also provided in module frames of the vehicle (2). The measurement arrangement particularly reduces bottleneck situations in equipment qualifying of processing tools (40) during fast ramp-up phases of, e.g., semiconductor manufacturing facilities, thereby saving costs. The construction is based on PGVs or AGVs and allows a fast operation directly at the location of a processing tool (40). With the possible exception of power supply or operator control, the measurement arrangement can operate fully autonomous. <IMAGE> |
