Abstract

See full text

A substrate processing system includes a multi-zone cooling apparatus to provide cooling for all or substantially all of a window in a substrate processing chamber. In one aspect, the apparatus includes one or more plenums to cover all or substantially all of a window in a substrate processing chamber, including under an energy source for transformer coupled plasma in the substrate processing chamber. One or more air amplifiers and accompanying conduits provide air to the one or more plenums to provide air flow to the window. The conduits are connected to plenum inlets at various distances from the center, to direct airflow throughout the window and thus address center hot, middle hot, and edge hot conditions, depending on the processes being carried out in the chamber. In one aspect, the one or more plenums include a central air inlet, to direct air toward the center portion of the window, to address center hot conditions.
