Closed loop pressure refers to using a feedback loop based on pressure instead of mass flow. A mass flow controller (MFC) will typically measure the mass 

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.

HATFIELD, Pa. (USA) August 25, - Brooks Instrument, a leader in precision fluid measurement and control technology, has released the new GP200 Series, the first fully pressure-insensitive pressure-based mass flow controller (P-MFC) designed specifically for etch and chemical vapor deposition (CVD) processes in semiconductor manufacturing.

Example 2 – pressure-based MFC: Traditional pressure- based MFCs measure pressure drop across a laminar flow element (LFE) (FIGURE 4). The valve must be placed upstream for two reasons. First, the pressure measurement is more accurate and stable if P2 is vacuum; second, this method requires a stable inlet pressure, P1. The downside to placing

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
