Cleaning with electrically charged aerosols
InactiveUS20060118132A1Easy to cleanEasy maintenanceSemiconductor/solid-state device manufacturingElectrostatic cleaningLiquid layerAerosol droplet
In a method for cleaning a wafer, the wafer is placed a processing chamber. A layer or film of liquid is provided on the wafer. Electrically charged aerosol droplets of a liquid are formed and directed to the workpiece. The charged aerosol particles accumulate on the workpiece. This creates an electrical charge on the workpiece. Contaminant particles on the workpiece are released and / or repelled by the electrical charge and are carried away in the liquid layer. The liquid layer is optionally continuously replenished with fresh liquid. The liquid layer may be thinned out in a localized aerosol impingement area, via a jet of gas, to allow the electrical charge of the aerosol to better collect on or near the surface of the workpiece.
