The pressure based MFC was introduced in the last decade and is now overtaking the use of the thermal MFC in critical etch applications. In 2002, Fugasity introduced a pressure base MFC

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.

Aug 25,  · Call 1-888-554-3569 Brooks Instrument Introduces First Fully Pressure-Insensitive Pressure-Based Mass Flow Controller for Etch and CVD Processes in Semiconductor Manufacturing The new GP200 Series improves flow measurement accuracy and repeatability in semiconductor manufacturing over the widest range of operating conditions in the industry.

Traditional pressure-based MFCs use two absolute pressure sensors to compute pressure drop. GP200 Series uses a novel sensor approach – an integrated assembly 

Mass flow controllers require the supply gas or liquid to be within a specific pressure range. Low pressure will starve the MFC of fluid and cause it to 

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.

Differential pressure MFCs measure the flow by measuring the pressure drop across a flow restrictor. The flow restrictor may be as simple as an 

Mass-Flo® Vapor Source Mass Flow Controller with Viscous Choked Flow. 1150C Mass-Flo® Vapor Source Mass Flow Controllers are pressure based measurement and control systems designed to meter and control vapor from low vapor pressure liquid and solid sources directly, without the need of a carrier gas using viscous flow through a choked orifice

P-Series, high performance mass flow controllers are designed for the most critical process applications where accuracy, repeatability as well as pressure

Abstract: A new type of pressure-based MFC has been developed based on a combination of absolute and differential pressure transducers.

Given the fundamental differences in technology between thermal and differential pressure mass flow units, differential pressure units do not 

If the MFC valve had a maximum differential pressure limitation of 250 psig, this would work well for operating the reactor at its maximum steady state pressure (1200 psig). However, many research reactors are required to change pressure during the test cycle or they may require the dispensed gas to generate the initial reactor pressurization.

A robust product portfolio consisting of SAM and Aera brand analog, digital, and pressure insensitive MFCs provide leading edge Mass Flow Control functionality. The offering is further
