RF generators are used in semiconductor manufacturing processes of physical vapor deposition (PVD), chemical vapor deposition (CVD), and etching, with vacuum capacitors used in the impedance matching network.
Liquid crystal display
High-current plasma with radio frequency(RF) generators is used to manufacture the LCD panels--- thin-model, big-screen televisions for example---with vacuum capacitors inside the impedance matching network.
The LCD technology is used for photovoltaic power Generating panel manufacturing. Vacuum capacitors are incorporated in the impedance matching network of RF generators for plasma generation.
Vacuum capacitors are used in communications equipment, transmission systems for short and medium wave broadcasting, aircraft antenna tuners used in harsh environments, and various mobile communications equipmant.
Medical - MRI
Vacuum capacitors are used in chemical ingredients analyzers and magnetic resonance imaging(MRI).
