Claim:
1. A method of operating an injector module assembly, comprising: injecting first gas for depositing a first material onto a substrate by a first reaction chamber in a deposition mode; discharging, away from the substrate, the first gas remaining after injecting the first gas onto the substrate through a first exhaust in the deposition mode; injecting separation gas into a passage by a separation gas injector to prevent the first gas from entering a second exhaust in the deposition mode; injecting second gas for removing a second material deposited on the injector module assembly through the first exhaust of the injector module assembly in a cleaning mode; injecting the separation gas into the passage by the separation gas injector to prevent the second gas from entering the separation gas injector in the cleaning mode; and routing the second gas from the first exhaust to the second exhaust of the injector module assembly in the cleaning mode through the passage to remove the second material deposited on a portion of the injector module assembly between the first exhaust and the second exhaust.
