Lid opening and closing device

A lid opening and closing device for a semiconductor manufacturing apparatus which comprises:

• a partition wall configured to divide a carrier conveying region and a substrate conveying region, the partition wall having a conveying gateway with an edge portion;
• a carrier including a carrier body and a carrier lid configured to removably engage with the carrier body, the carrier body having a substrate takeout opening with an edge part, the carrier lid having an internal space and an opening on the front surface thereof, the edge part of the substrate takeout opening of the carrier body being configured to make contact with the edge portion of the conveying gateway;
• and
• an opening/closing door configured to open and close the conveying gateway, the opening/closing door including a lid removal mechanism configured to enter the carrier lid to release engagement of the carrier lid with the carrier body and to hold the carrier lid, the lid opening and closing device comprising:
• an exhaust port configured to discharge therethrough an atmospheric gas from a closed space formed between the carrier making contact with the edge portion of the conveying gateway and the opening/closing door;
• and
• an exhaust part provided in the opening/closing door, the exhaust part configured to enter the internal space of the carrier lid through said opening of the carrier lid and to discharge therethrough an atmospheric gas existing in the internal space of the carrier lid.
