20 - (+5) = 15 PSID The 5 PSIG backpressure will try to reduce the gas flow through the controller. This 15 PSID pressure will force considerably less gas through a given orifice than would the 35 PSID pressure. The MFC valve is a variable orifice and the orifice varies in size depending on the flow rate, density, viscosity, and pressure.

Aug 27, · The P-MFC operates well in high-vacuum conditions and above atmospheric pressure conditions that are intrinsic to etch and CVD processes, states the company. In comparison, conventional discrete P-MFCs can operate under high-vacuum conditions but degrade in performance and control range as the outlet pressures increase.

A mass flow controller (MFC) has a standard envelope with an enclosure and a corresponding base. A pressure transducer is communicatively coupled to a process gas in a proportional inlet valve without being physically coupled to the base. The space formerly occupied by the pressure transducer is available for additional component integration, or reduction of the standard envelope size.
