Method and system for measuring a flow rate in a solid precursor delivery system
Abstract:
Improved measurement accuracy for determining the flow rate of precursor vapor to the deposition tool, particularly for use with low vapor pressure precursors, such as ruthenium carbonyl (Ru3(CO)12) or rhenium carbonyl (Re2(CO)10). In one embodiment, the system includes a differential pressure manometer is provided for measuring the flow rate. A method of measurement and calibration is also provided.
