Abstract:
Methods and apparatuses for delivering a process gas to a processing chamber are provided. A mass flow controller includes a first flow line for introducing a process fluid and an inlet valve disposed along the first flow line for controlling a flow rate of the process fluid. The mass flow controller includes a second flow line for introducing a carrier fluid into the mass flow controller and a micro-electro-mechanical system (MEMS) Coriolis sensor for providing a density signal and a mass flow rate signal for a mixture of the process fluid and the carrier fluid. The mass flow controller provided includes an outlet valve for controlling a mass flow rate of the mixture that is output by the mass flow controller as well as a controller for operating the inlet valve based on the density signal and for operating the outlet valve based on the mass flow rate signal.

Claim (Index 8):
The mass flow controller of  claim 7 , wherein the controller is further configured to calculate a mass flow rate specific to the process fluid based on the fluid mix ratio and based on the mass flow rate signal, and wherein the controller is further configured to adjust the outlet valve based on the calculated mass flow rate specific to the process fluid to achieve a desired mass flow rate specific to the process fluid.
