Abstract
A sputtering system includes a vacuum chamber, a sputtering electrode provided in the vacuum chamber, a target supported on the sputtering electrode with a front surface of the target and a substrate disposed in the vacuum chamber so as to be opposed to each other. A high-frequency or DC power source supplies a high-frequency or DC power to the sputtering electrode to generate plasma on the target, and an antenna is provided for generating an electromagnetic wave and is disposed outside the vacuum chamber and near the target. An electromagnetic-wave inlet window for introducing into the vacuum chamber an electromagnetic wave generated from the antenna is provided in a wall of the vacuum chamber.
