Abstract
In one embodiment, a modular method of making mass flow controllers for delivery of a plurality of process gases includes providing a plurality of monolithic bases, each of the monolithic bases having a plurality of flow component mounting regions. A first set of flow components are coupled to the flow component mounting regions of a first of the monolithic bases to form a mass flow controller having a first set of operating characteristics. A second set of flow components are coupled to the flow component mounting regions of a second of the monolithic bases to form a mass flow controller having a second set of operating characteristics which are different from the first set of operating characteristics.
