Abstract: A vacuum sputtering cathode has a hollow structure (2) able to rotate about its axis and a magnetic confinement circuit (3) arranged peripherally about said structure. The cathode according to the invention is particularly suitable for the rapid dissipation of the thermal energy given off by the sputtering process and in particular for the sputtering of metals with a low melting point.

Abstract: The invention relates to a cathode (1) intended for spraying thin layers of materials onto one or more substrates using the cathodic sputtering method.It consists of a structure (V-shaped) comprising an electrical supply, cooling members and two sputtering planes (6, 7) in which there are arranged side by side at least two strips of target material joined at their ends forming a single continuous target material track extending between and positioned in at least two separate planes, the track being confined within a single magnetic circuit, which also extends between and is positioned in the at least two separate planes, with the result that it is possible to treat simultaneously two substrates (44) arranged on their supports (43) on each side of the cathode (1).The cathode (1) according to the invention is particularly recommended for sputtering substrates of large size, such as glass.
