Abstract
A load port and a multi-use carrier are provided. The load port includes a carrying board, two gas-inlet nozzles disposed on the carrying board, and two gas-outlet nozzles disposed on the carrying board. Each of the two gas-inlet nozzles has a shared gas-inlet channel. Each of the two gas-outlet nozzles has a first gas-outlet channel and a second gas-outlet channel that is spaced apart from the first gas-outlet channel. The shared gas-inlet channels of the two gas-inlet nozzles are selectively cooperated with the first gas-outlet channels of the two gas-outlet nozzles so as to be jointly configured to spatially communicate with a first wafer cassette. The shared gas-inlet channels of the two gas-inlet nozzles are selectively cooperated with the second gas-outlet channels of the two gas-outlet nozzles so as to be jointly configured to spatially communicate with a second wafer cassette.
