Key Technology and Structure Design of Cylindrical Rotating Cathode Target for Magnetron Sputtering
ABSTRACT
Cylindrical rotating cathode target for magnetron sputtering (cylindrical rotating target) since the invention to now, has been widely used in industrial area functional film production preparation. Although after decades of development and innovation, there are still some problems in industrial production. For example, the magnetic field distribution on the target surface which vertical electric field was uneven, causing the target materials was sputtered etching don't even, making the target material utilization ratio decreased.The design of the cooling water circulation system is not reasonable, makes the cooling heat transfer is not enough, causing its working poor stability, finally affects the coating quality. The key technologies of the system has been research based on the glow discharge, magnetron sputtering, plasma, electromagnetic field and heat transfer theory. Realized industrialized scale production of a new type of magnetic field structure with the design of cylindrical rotating target of the research objective.
