Abstract: A valve to allow digitally addressable flow controllers is provided. An array of micromachined valves having a range of flow capacities and individually addressable while functioning in an On/Off mode allows flow controllers and similar devices high resolution, linearity and reproducibility. The incorporation of diamond or diamond-like materials in all flow paths extends the application of the valves to corrosive materials and permits higher process temperatures and lower particulate generation.
