SUBLIMATION CONTROL USING DOWNSTREAM PRESSURE SENSING

A system to control gas flow includes an ampoule to store a solid precursor. A heater is to heat the ampoule and to sublimate the solid precursor into a gaseous precursor. A mass flow controller is to regulate a flow of gaseous precursor from the ampoule to a substrate processing chamber. A pressure...
