摘要:
A semiconductor manufacturing apparatus includes a leakage preventing device for preventing outward leakage of electromagnetic waves through an opening defined when a pod having a substrate accommodated therein is mounted on the semiconductor manufacturing apparatus. The leakage preventing device includes at least one electromagnetic wave shielding plate and is provided at the semiconductor manufacturing apparatus side. The apparatus also includes a first electromagnetic wave shielding plate, which is openable and closable so that an opening defined when a carrier in the standard mechanical interface pod is moved downwardly is closed by the plate, and a second electromagnetic wave shielding plate, which has an openable and closable slit provided between an indexer for moving the carrier in the standard mechanical interface pod downwardly and a conveyance robot for conveying the substrate.

A substrate holding device includes a vacuum supplying device for supplying a vacuum to a holding surface to hold a substrate, a hollow member surrounding at least a portion of the holding surface and movable between a position in which the holding member protrudes from the holding surface and a position in which the hollow member does not protrude from the holding surface, and a moving mechanism for relatively moving between the hollow member and the holding surface.

A substrate holding apparatus includes a pump, serving as a suction source, a conveying chuck for holding a wafer substrate by suction, a connection arrangement, including parallel lines intermediate the connection arrangement, for conneting the pump to the chuck, and a valve arrangement including at least one valve provided in at least one of the parallel lines. By selecting one of the parallel lines by controlling opening/closing of these valves, the conductance of the connection line is adjusted, whereby the optimum suction pressure for the chuck is set.

A wafer holding device of the vacuum attraction type includes a structural member having a protrusion for supporting a wafer and elastic members made of a material having an elasticity modulus smaller than that of the wafer and that of the structural member. The elastic members are distributed on a wafer attraction plane of the structural member.

A processing apparatus of the present invention processes for a wafer 9. The processing apparatus includes an XY stage 6 which includes a wafer chuck 8 which holds the wafer 9 and an elevating device which rises relative to the wafer chuck 8 to hold the wafer 9, and a wafer conveying robot hand 14 which conveys the wafer 9 from the XY stage 6 at a wafer transfer position 18. The XY stage 6 moves to change a direction at an angle between 30 degree and 120 degree via the wafer transfer position 18 in a state where the elevating device rises relative to the wafer chuck 8. The wafer conveying robot hand 14 has a shape which does not interfere with the XY stage 6 which moves to change the direction at the angle when the wafer conveying hand 14 is positioned at the wafer transfer position 18.

摘要:
A pod attachable to an outside surface of a grounded electromagnetic-shielded chamber. The chamber has a door and a flange portion, around the door, on the outside surface and contains a micro-device manufacturing apparatus. The pod includes walls configured to contain a substrate and having an opening, the walls including a flange portion configured to contact the flange portion of the chamber, and a lid configured to openably close the opening, the substrate being transferred between the pod and the chamber through the opening. Also included is an electromagnetic shield member. The electromagnetic shield member is arranged over the walls and on the flange portion of the walls. The electromagnetic shield member on the flange portion of the walls is configured to contact the grounded flange portion of the chamber while the pod is attached to the outside surface.
