A substrate body transfer apparatus, and an operating method therefor, capable of inserting and extracting substrate body into and from a cassette using air conveyance without employing a transfer mechanism such as those in which direct contact is made with the substrate body when inserting or extracting a thin plate-shaped substrate body into or from a cassette. The substrate body transfer apparatus is employed when thin plate-shaped substrate body are extracted from or inserted into cassettes which store the substrate body. The substrate body transfer apparatus includes an air conveyance hand which is provided with a plurality of gas nozzles at the conveyance surface which opposes the rear surface of the substrate body and which has the function of conducting the flotation or grounding of the substrate body, the catching or launch of the substrate body, or the centering of the substrate body; and a cassette platform which has a unitary structure comprising a cassette platform seat on which the cassette is placed and which is provided with a mechanism for horizontally advancing and retracting the cassette with respect to the air conveyance hand, and a mechanism for raising and lowering the cassette platform seat at a predetermined pitch.

Substrate transfer device and operating method thereof

An air stream transfer apparatus capable of preventing particles in a transfer passage from adhering to an object to be processed and removing the particles. The apparatus includes that of a transfer face and a transfer passage partition both constituting a transfer passage, which are made of an electroconductive material and each have a thin insulating layer on the surface. A planer dust collecting electrode is opposed to an object to be processed and mechanism is provided for bringing the dust collecting electrode and the face to be cleared of dust close to each other while jetting air. A mechanism is provided for applying voltages between the transfer face and the dust collecting electrode and between the transfer passage partition and the dust collecting electrode and between the transfer passage partition and the dust collecting electrode. Another apparatus is characterized in that a transfer face and a transfer passage partition both constituting a transfer passage are made of an electroconductive material and each has a thin insulating layer on the surface. A mechanism for transferring a pre-charged semiconductive plate-shaped body along the transfer passage is provided, and the semiconductive plate-shaped body used as a dust collecting electrode.

Air stream transfer apparatus

A substrate body transfer apparatus which is capable of isolating the atmospheres of an external processing apparatus and an air conveyance apparatus and preventing the mutual contamination thereof, and which is capable of conducting the transfer of substrate bodies at a low level of particulate matter and contamination which satisfies the ultra-clean level. The substrate body transfer apparatus is provided with a vacuum container having an entrance and exit which communicate with the interior space of an air conveyance apparatus and the interior space of an external processing apparatus; a horizontal disc-shaped upper part valve and lower part valve are housed within the vacuum container and after the substrate body has been placed in a space surrounded by the upper and lower valves and this space has been sealed, the space is evacuated or the gas therein is replaced.
