Verfahren und Vorrichtung zur Erzeugung hochangeregter Plasmen mittels Funkenentladung fuer die Abscheidung duenner Schichten
The device has a dielectric tube of SiO2 with a wall thickness of 2 mm, a length of 7 cm and an inner diameter of 7 mm. Into one end is set a cathode  part, that is fabricated from metal, semiconductor material or carbon. An anode  is located at the other end, and the separating distance is 8 cm. The anode may also be made from metal, semiconductor material or carbon. A capacitor discharge is used to trigger the plasma in the tube. The anode is located in an argon gas filled space. The arc discharge in the tube produces a plasma that flows from the anode side. USE - For processing of thin dielectric sheets, such as ceramic materials ADVANTAGE - Ensures pulsed discharge onto dispensing target.
