What is sputtering and its types? Sputtering is a physical process in which atoms in a solid-state (target) are released and pass into the gas phase by bombardment with energetic ions (mainly noble gas ions). Sputtering is usually understood as the sputter deposition, a high vacuum-based coating technique belonging to the group of PVD processes. What kind of coating is DC sputtering used for? Traditional DC Sputtering is a cost effective way of applying metal target coatings that are electrical conductors like gold. However, DC Sputtering is limited when it comes to dielectric target materials – coatings which are non-conducting...
