Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 17:
18. The device of claim 17, wherein the operations comprise:
detecting, from a second load port adjacent to the interface module, docking of a second FOUP onto the second load port;
controlling the gas supply to initiate a second gas flow, wherein the second gas flow creates a second laminar air curtain across the second opening;
controlling the second interface door of the interface module adjacent to the second FOUP to reveal the second opening after control of the gas supply to initiate the second gas flow;
controlling the operating machine to transfer the semiconductor wafer through the second opening;
controlling the second interface door to cover the second opening; and
controlling the gas supply to halt the second gas flow after control of the second interface door to cover the second opening.
