A deposition apparatus includes a gas inflow tube, a plasma electrode, a substrate support functioning as an opposite electrode to the plasma electrode and mounting a substrate thereon, a plasma connector terminal connected to the plasma electrode, a first voltage application unit connected to the plasma connector terminal to apply a voltage thereto in a continuous mode, and a second voltage application unit connected to the plasma connector terminal to apply a voltage thereto in a pulse mode. The voltage applied by the first voltage application unit is an RF voltage of about 13.56 MHz, and the voltage applied by the second voltage application unit is a VHF voltage ranged from about 27 MHz to about 100 MHz.
摘要:
A plasma based ion implantation system capable of generating a capacitively coupled plasma having beneficial characteristics for an ion implantation, including the generation of necessary ions and radicals only for an ion implantation process instead of generating an inductively coupled plasma, which generates unnecessary ions and excessively dissociates radicals. The plasma based ion implantation system easily controls plasma ions implanted by cleaning a vacuum chamber, minimizes problems of unnecessary deposition and occurrence of contaminants and increases the number of components used only for the plasma ion implantion by reducing the deposition of polymer layer on a workpiece. The plasma based ion implantation system easily control uniformity of the plasma by using a flat type electrode, thereby easily ensuring uniformity of plasma ions implanted into the workpiece.
