“[1] The Pinnacle range of DC Power Supplies are adapted to provide power to the semi-conductor manufacturing “sputtering” process. Sputtering is the process used in the manufacture of semiconductors. It involves bombarding a target (i.e. silicone substrate) with atoms. These atoms are highly charged and when they come into contact with the atoms of the substrate, it causes a small explosion that ejects the atom from the substrate. This then leaves a space. This is the process by which silicon substrates are “etched”
