MULTI-LID STRUCTURE FOR SEMICONDUCTOR PROCESSING SYSTEM

Abstract:

Exemplary substrate processing systems may include a chamber body defining a transfer region. The systems may include a first lid plate seated on the chamber body along a first surface of the first lid plate and defining a plurality of apertures through the plate. The first lid plate may also define a recessed ledge about each aperture. The systems may include a plurality of lid stacks equal to a number of apertures of the plurality of apertures. Each lid stack may be seated on the first lid plate on a separate recessed ledge of the first lid plate. The plurality of lid stacks may at least partially define a plurality of processing regions vertically offset from the transfer region. The systems may also include a second lid plate coupled with the plurality of lid stacks.
