摘要:
To enable appropriate wafer mapping in the case where a wafer is stored at the highest level, which is provided as a reserve, of a pod, a load port apparatus drives a mapping frame that supports a sensor by a first driving unit that drives the mapping frame in a first direction parallel to the direction along which wafers in the pod are arranged in an overlapping manner and a second driving unit that drives the mapping frame in a second direction that crosses the first direction in such a way as to form an acute angle in the side in which the sensor starts the mapping.

A closed container in which a reticle etc. is stored and kept is provided with a pressure sensor, transmission means for transmitting data on the pressure, a controller that controls the operation of them, and a battery serving as a power source of the above elements. The controller has a sleep mode in which it causes the transmission means to transmit the data on the pressure at regular intervals and an active mode in which it causes the transmission means to transmit the data on the pressure when necessary in response to an externally supplied command. By the above described configuration, the pressure in the interior of the container can be checked appropriately.

A partial pressure of oxidizing gas in an opened state FOUP fixed in a FIMS system is reduced when the FOUP is closed. Purge gas supply nozzles are placed outside of two vertical sides of an opening portion (10) within the FIMS. A curtain nozzle is additionally installed which can form a gas curtain from purge gas above the top side of the opening portion (10). When a pod (2) is closed with a lid (4), a door opening/closing mechanism keeps the lid (4) at a given angle with respect to the flowing direction of curtain gas for a given period of time, and hence purge gas supplied to the gas curtain is additionally put into use for the purging of the interior of the pod by the lid 4.
