Abstract:
A sputtering device comprising:a vacuum chamber; a sputtering electrode for supporting a target, said sputtering electrode being arranged in said vacuum chamber such that a front surface of the target to be supported by said sputtering electrode opposes a substrate disposed in said vacuum chamber; a power source connected to said sputtering electrode for supplying one of a high-frequency power and a DC power to said sputtering electrode so as to generate plasma at the target; an antenna for generating an electromagnetic wave, said antenna being positioned outside said vacuum chamber and near said sputtering electrode so as to oppose a rear surface of the target to be supported by said sputtering electrode; an electromagnetic-wave inlet window for introducing the electromagnetic wave generated by said antenna into said vacuum chamber, said electromagnetic-wave inlet window being arranged in a wall of said vacuum chamber at a rear surface side of the target to be supported by said sputtering electrode and outside of a peripheral edge of the target with respect to a center of the target.
