Abstract

Embodiments generally relate to gas circuits for distributing gases for processing of substrates applicable for semiconductor manufacturing. In one or more embodiments, flow controllers of a gas circuit are used to stabilize, distribute, and switch gases for processing of substrates applicable for semiconductor manufacturing. In one or more embodiments, a gas circuit includes one or more first ratio flow controllers operable to control a flow of a first gas, a plurality of first valves operable to open and close the flow of the first gas, one or more second ratio flow controllers operable to control a flow of a second gas, and a plurality of second valves operable to open and close the flow of the second gas. The gas circuit further includes a first set of gas lines connected to the first ratio flow controllers, and a second set of gas lines connected to the second ratio flow controllers.
