Abstract:
An apparatus configured to remove metal etch byproducts from the surface of substrates and from the interior of a substrate processing chamber. A plasma is used in combination with a solid state light source, such as an LED, to desorb metal etch byproducts. The desorbed byproducts may then be removed from the chamber.
