Vacuum coating by sputtering has established a leading position for the deposition of thin films because of its relatively easy scalability to high volumes and sizes, its good control of most layer characteristics, and its wide variety of available materials and possible coating stacks. The technology is commonly accepted and widely used in the architectural and automotive industries. In display and PV applications, however, the use of rotatable technology has been introduced more recently.
Within the large area coating business, the rotating cylindrical magnetron concept has proven to offer superior properties relative to the planar concept and to satisfy most industrial requirements. The geometry and sputter performance of rotating cylindrical sputter targets result in several advantages relative to planar sputter targets. Read More
