摘要: A method and apparatus for a gas delivery system to deliver a precursor from a vessel to a process chamber via a process gas produced by flowing a first carrier gas into the vessel and combining with a second carrier gas flowing through a bypass around the vessel and a precursor monitoring apparatus disposed between the process chamber and the vessel. The precursor monitoring apparatus has a gas analyzer to generate a first signal indicative of a concentration of the precursor in the process gas or to a signal indicative of a flow rate of the process gas.

摘要: Embodiments of the invention provide a method for monitoring and controlling delivery of a precursor from an ampoule in a process chamber. In one embodiment, the method provides flowing a first carrier gas at a first flow rate through a vessel containing a chemical precursor to form a first precursor gas, combining a second carrier gas at a second flow rate and the first precursor gas to form a second precursor gas, measuring a concentration of the chemical precursor within the second precursor gas, and calculating a mass flow rate of the chemical precursor. In one example, a tantalum-containing film is deposited on a substrate during an atomic layer deposition process by heating an ampoule containing pentakis(dimethylamido) tantalum to a temperature within a range from about 60° C. to about 75° C., and forming a precursor gas by flowing a carrier gas through the ampoule.
