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 19):
The apparatus of  claim 1 , further comprising:\n a second gas inlet; a fifth surface, wherein the second gas inlet is configured to deliver a second process gas through the fifth surface; a plurality of second gas distribution ports; a sixth surface, wherein the plurality of second gas distribution ports are configured to deliver the second process gas through the sixth surface; a seventh surface interposed between the fifth surface and the sixth surface; an eighth surface interposed between the sixth surface and the seventh surface; a plurality of second gas flow passages interposed between the fifth surface and the seventh surface; and a plurality of second holes passing through the eighth surface, wherein:\n the fifth surface and the seventh surface at least partially define a second inlet plenum volume that is fluidically connected with the second gas inlet, \n the sixth surface and the eighth surface at least partially define a second gas distribution plenum volume that is fluidically connected with each second gas distribution port of the plurality of second gas distribution ports, \n each second gas flow passage of the plurality of second gas flow passages has a corresponding first end that fluidically connects with the second inlet plenum volume and a corresponding second end that fluidically connects with the second gas distribution plenum volume via a corresponding second hole of the plurality of second holes, and \n each second gas flow passage of the plurality of second gas flow passages has a flow resistance that is substantially similar to the flow resistance of each other second gas flow passage.
