摘要

Aluminum nitride ion beams were extracted from a plasma sputter type ion source with an actively cooled Al sputter target. The Al target holds permanent magnets to form a magnetron magnetic field geometry and excites plasma by the applied 13.56 MHz RF voltage. The extracted ion beam current decreased as the temperature of the target increased due to plasma operation. The active air cooling of the target decreased the temperature to stabilize the intensity of the ion beam current. The active cooling also reduced the amount of dusts formed in the source during the plasma operation.
