Abstract:
1. A method for processing a wafer, comprising: providing a flow chamber having a first gas inlet for allowing a first gas to flow in the flow chamber; providing a wafer inlet at which the wafer enters the flow chamber, the wafer inlet being coupled to a wafer storage device; providing a wafer outlet at which the wafer exits the flow chamber, the wafer outlet being adapted to be coupled to a wafer processing apparatus; providing a robotic apparatus in the flow chamber for moving the wafer from the wafer inlet to the wafer outlet; and allowing a second gas from a second gas inlet to enter the flow chamber such that a mixture gas including a combination of the first gas and the second gas flows into the wafer storage device, such that the amount of contaminants entering the wafer storage device is reduced, wherein the mixture gas has a substantially laminar flow in the flow chamber.
