Abstract
A magnetron sputtering coating device includes a deposition chamber, sputtering cathodes, a rotating stand within the deposition chamber, a support platform on the rotating stand, a first rotation system for driving the rotating stand to rotate around a central axis of the rotating stand, and a baffle fixed on the rotating stand. The sputtering cathodes are arranged around and perpendicular to the rotating stand.
