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 17):
A mass flow controller, comprising:\n a mixing and sensing module for mixing a process fluid and a carrier fluid into a mixture, the mixing and sensing module provides a density signal and a mass flow rate signal for the mixture; an inlet valve for controlling a flow rate of process fluid entering the mixing and sensing module; an outlet valve for controlling an output flow rate of the mixture exiting the mixing and sensing module; and a controller for calculating a fluid mix ratio of process fluid to carrier fluid based on the density signal and for calculating a mass flow rate of the mixture based on the mass flow rate signal for the mixture, wherein the controller is configured for adjusting the inlet valve based on the fluid mix ratio and for adjusting the outlet valve based on the mass flow rate of the mixture.
