Abstract
In a method of switching magnet flux distribution, a magnet is arranged on a rear side of a backing plate with respect to a target holding side thereof in a magnetron sputtering cathode, and placing an article that exhibits ferromagnetism at room temperature on the target holding side of the backing plate or removing the article therefrom so that the magnet flux distribution is switched between a balanced distribution of the magnetic flux and unbalanced distribution of the magnetic flux.
