The Design of High-End Pressure Control Valve (PCV) Control System with DeviceNet Interface in Semiconductor Wafer Foundry
Keywords:Pressure Control Valve (PCV), DeviceNet, Semiconductor Industry
AbstractThis paper presents a novel design of control system with features of DeviceNet interface and remotely accessible database via Internet for high precision pressure control valve (PCV). This PCV control system is particularly suitable for pressure/flow process control within vacuum chamber in the fully automated manufacturing machines for semiconductor industry ranging from wafer foundry, LCD/LED panel plant to photoelectric plant. In 2015, Taiwan-based Fred Automation Corporation has been successfully implemented this PCV control system for field testing in the evaluation of performance and benefits.
