An arrangement detector for plate-shaped objects and a lord port including the same are provided. The arrangement detector for plate-shaped objects includes a judgement window setting means, a shape determination means for determining a shape matching rate by superimposing the judgement window on the image captured by the imaging means, and an object judgement means for judging the plate-shaped objects do not exist in the judgement window overlaid on the image captured by the imaging means, in case that the shape matching rate determined by the shape determination means is equal to or less than a predetermined value. A first reference line is a continuous straight line in the judgement window, and a second reference line is a collection of discontinuous line segments linearly arranged in the judgement window.

Arrangement detector for plate-shaped object and load port including same

A load port apparatus connects a main opening of a wafer transportation container to a frame opening. The apparatus includes an installation unit, a frame unit, a flange clamp unit, and a detection unit. The installation unit includes an installation table configured to install the container and relatively move to the frame opening. The frame unit is upright upward from the installation unit and includes the frame opening. The flange clamp unit includes an engagement section and a drive section. The engagement section is engageable with a flange surrounding an outer circumference of the main opening. The drive section drives the engagement section to carry out an engagement operation and a separation operation. The detection unit detects the engagement operation by the flange clamp unit with classification into a normal engagement operation and an abnormal engagement operation.

Load port apparatus and method of driving the same

A gas purge apparatus, a load port apparatus, and a gas purge method are capable of filling a container with a cleaning gas without leaning the container to be purged. The first and second purge nozzles are configured to be escalated so that the first purge nozzle-contacts with the first purge port-whose distance to the regulating distanceis near before the second purge nozzle-contacts with the second purge port-

Gas purge apparatus, load port apparatus, and gas purge method

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.

Load port apparatus and method of detecting object to be processed

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 () 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 (). When a pod () is closed with a lid (), a door opening/closing mechanism keeps the lid () 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

Method of processing an object in a container and lid opening/closing system used in the method

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.
