Abstract:
1. A system for reducing He backside faults when processing a wafer having a process side and a backside opposite the process side, comprising: a cleaning module for cleaning the backside of the wafer so as to remove un-wanted particles therefrom before performing subsequent processing tasks on the process side of the wafer, the cleaning module being configured to only clean the backside of the wafer so as not to effect the process side of the wafer, the cleaning module comprising, a cleaning chamber; an applicator for dispensing a cleaning solution on the back side of the wafer, a brush for scrubbing the backside of the wafer; and a wafer holder for holding the wafer relative to the brush; and a processing module for performing processing tasks on the process side of the wafer the processing module comprising; a process chamber within which processing takes place; and a chuck for holding the backside of the wafer relative to a top surface of the chuck, the chuck including a heat transfer system for controlling the temperature of the wafer, the heat transfer system being configured for distributing He gas to the backside of the wafer during processing; a transport module configured to remove the cleaned wafer from the cleaning modules to move the cleaned wafer from the cleaning module to the processing module, and to place the cleaned wafer on the chuck inside the process chamber of the processing module without performing any intervening manipulations during said movement.
