To eliminate the possibility of contamination, vacuum chambers are used in a variety of industrial processes, particularly in the semi-conductor manufacturing arena, where the slightest amount of contamination can destroy the substrate. These ultra high vacuum applications are frequently utilized in semi-conductor manufacturing processes, because even the slightest degree of contamination can be disastrous in this industry. As we mentioned earlier, thermal vacuum chambers are an ideal environment for testing devices and instruments that must operate in outer space. Many vacuum chambers are constructed of aluminum, because aluminum, unlike other metals, is not magnetic.Vacuum chambers are frequently constructed with multiple ports, covered with flanges, to allow instruments or windows to be installed in the walls of the chamber. In applications that require only low vacuum levels, rubber seals are used. In higher vacuum applications, the flanges have hardened steel knives welded onto them, which cut into a copper gasket when the flange is bolted on.A type of vacuum chamber frequently used in the field of spacecraft engineering is a thermal vacuum chamber,, which provides a thermal environment representing what a spacecraft would experience in space. This type of application will also utilize a highly advanced vacuum pump.
