The Leybold LH Z400 is dedicated to the deposition of materials (both metals and oxides) and consists of a high-vacuum chamber and sample holder up to 4 inches.
In this technique, ionized particles due to the activation of a plasma of an inert gas (e.g. Ar) are forced to impact onto a target (the material to be deposited) causing the ejection of atoms and/or molecular clusters, that later will condense on the substrate surface for the coating formation.
This setup is generally used in the deposition of films with thickness > 100 nm, in the fabrication of metal contacts (whether transferred by optical lithography or with shadow mask) and oxide coatings.

CASE STUDIES

Diamond spectrometers for fast neutron, arranged as single pixel and multi-pixel matrix, were metallized with the magnetron sputtering to obtain almost-ohmic contacts on diamond, inducing extremely reduced space-charge conditions.
