MODULAR ZONE CONTROL FOR A PROCESSING CHAMBER

Abstract:

Exemplary semiconductor processing chambers may include a faceplate assembly characterized by at least one surface defining a number of voids. Each void is configured to receive an interchangeable thermal body that can be selected from multiple interchangeable thermal bodies. Exemplary semiconductor processing chambers may also include a gas box characterized by movable members. Each movable member is configured to engage a delivery port and is movable to provide flow control for a gas being delivered to the processing volume through a gas flow path. Zoned flow and/or temperature control may be provided by the faceplate assembly, the gas box, or both.
