Applied Materials AFC-550 Mass Flow Controller

Applied Materials AFC-550 Mass Flow Controller meters and regulates nitrogen gas in semiconductor processing equipment over a 60 to 3000 sccm range, delivering precise, repeatable flow for purge, gas balancing, and process gas delivery. The AFC-550 packages a mass-flow sensor, control electronics, and a valve in a compact assembly to maintain setpoint flow under real-world chamber conditions. Mass flow controllers of this type are typically driven by analog or digital control signals and are calibrated for the specific gas; in this case, nitrogen, ensuring consistent performance within the 60–3000 sccm bandwidth across AMAT tool platforms. Typical applications include nitrogen purging and flow balancing in deposition, etching, and cleaning steps within semiconductor processing equipment.
