Abstract
The present invention is a method for carrying a wafer, wherein in taking out the wafer from a closed container and carrying the wafer by a carrier robot or in taking in the wafer carried by the carrier robot into the closed container, when a latchkey is rotationally driven for fixing and unfixing a lid relative to a container body of the closed container mounted on a load port frame by a latchkey-driving mechanism provided on a load port door that can fit with a wafer carrying-in/out port of a carrying room and that holds the lid of the closed container to enable removal from the wafer carrying-in/out port, the latchkey is rotationally driven at a rotation rate of 60 deg/sec or less. This provides a method for carrying a wafer and wafer-carrying apparatus that can reduce an amount of dust generated when the lid of the closed container is opened and closed or when the load port door is raised and lowered for carrying the wafer.
