A vacuum variable capacitor is a variable capacitor which uses a high vacuum as the dielectric instead of air or other insulating material. This allows for a higher voltage rating than an air dielectric [1] using a smaller total volume.

What is a Vacuum Capacitor? A capacitor is a passive electrical component that is capable of storing electrical charges. A capacitor consists of two conductive surfaces called electrodes, which are usually placed very close to each other.

Vacuum capacitors (VCs) are an integral part of semiconductor manufacturing processes. VCs are used in the impedance matching networks which enable physical vapor deposition (PVD), chemical vapor deposition (CVD) and etching. LCD technology is used for the manufacture of photovol-taic power generating panels (solar cells).
