The systems typically come with turbo molecular pumps backed by Edwards dry pumps. On most systems, all valves on the system are electro-pneumatic for ease of operation and will automatically close to a safe position on power failure. A standard Mass Flow Control unit (as opposed to a needle valve) provides for precise and reproducible process gas flow during deposition. Systems with multiple MFCs are readily available. Deposition pressure is monitored and controlled using a heated capacitance manometer whose output is fed into a closed-loop VAT gate valve. The desired process pressure can then be accurately controlled from 1 to 500 mTorr. Base vacuum is measured with a Bayard Alpert Ion gauge. The chamber and rough line pressures are also monitored with Convectron gauges.
