摘要：
Mass flow controller (MFC) designs must evolve to meet the need for ever more precise control of chemical and gas precursors used in semiconductor manufacturing. The flow-bypass thermal MFC technology that has been proven over decades of use can be extended to atomic-layer deposition (ALD) processes that ultimately specify chemicals in terms of moles/pulse instead of cubic-centimeters/min. Computational fluid dynamics (CFD) modeling can reduce hardware development time by cutting the number of iterations needed to handle nonlinearities in sensors and hysteresis in valves.
