Abstract:
Showerheads for semiconductor processing equipment are disclosed that include various features designed to minimize or eliminate non-uniform gas delivery across the surface of a wafer due to gas flow transients within the showerhead.

Claim (Index 1):
An apparatus comprising:\n a first gas inlet; a first surface, wherein the first gas inlet is configured to deliver a first process gas through the first surface; a plurality of first gas distribution ports; a second surface, wherein the plurality of first gas distribution ports are configured to deliver the first process gas through the second surface; a third surface interposed between the first surface and the second surface; a fourth surface interposed between the third surface and the second surface; a plurality of first raised bosses that extend up from the second surface towards the fourth surface; a plurality of first gas flow passages interposed between the first surface and the third surface; and a plurality of first holes passing through the fourth surface, wherein:\n the first surface and the third surface at least partially define a first inlet plenum volume that is fluidically connected with the first gas inlet, \n the second surface and the fourth surface at least partially define a first gas distribution plenum volume that is fluidically connected with each first gas distribution port of the plurality of first gas distribution ports, \n each first gas flow passage of the plurality of first gas flow passages has a corresponding first end that fluidically connects with the first inlet plenum volume and a corresponding second end that fluidically connects with the first gas distribution plenum volume via a corresponding first hole of the plurality of first holes, \n each first raised boss of the plurality of first raised bosses is centered on a corresponding first hole of the plurality of first holes and has a corresponding top surface facing the fourth surface that is offset from the fourth surface by a corresponding first distance, and \n each first gas flow passage of the plurality of first gas flow passages has a flow resistance that is substantially similar to the flow resistance of each other first gas flow passage.
