Oct 26,  · HATFIELD, Pa. (USA) October 26, - Brooks Instrument, a world leader in advanced flow, pressure, vacuum and vapor delivery solutions, will feature its new GP200 Series pressure-based mass flow controller (P-MFC) at SEMICON Europa, November 16-19, in Munich, Germany. The company will be exhibiting in booth B1572.

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.

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

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.

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.

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.

The GP200 Series P-MFC operates well in high-vacuum conditions and above atmospheric pressure conditions that are intrinsic to etch and CVD processes. In comparison, conventional discrete P-MFCs can operate under high-vacuum conditions but degrade in performance and control range as the outlet pressures increase.
