Simultaneously, a twin rotary double-cylinder type magnetic controlled sputtering target is utilized, a deposited compound film uses the form of intermediate-frequency electric discharge, the stability of sputtering process is enhanced, and the quality of the deposited film is raised.
Description
Technical field
The utility model relates to a kind of large-area vacuum plated film medium frequency magnetron sputtering target, can be widely used in the industries such as photoelectron, the energy, communication, building materials and machinery.
Background technology
Magnetron sputtering target is one of main device in the large-area vacuum filming equipment, needs insulating compound films such as a large amount of deposition oxides, nitride in the modern optical conductive film product, so widespread use intermediate frequency reaction magnetocontrol sputtering technology; What use in the vacuum coating film equipment now mainly is plane magnetic controlled sputtering target, and its permanent magnet and target all are actionless, and the etched area of target is a fixed like this; Therefore have following shortcoming during plane magnetic controlled sputtering target deposition of insulative material film: 1, because the etched area of target is a fixed, the utilization ratio of target is very low, can only reach 40% at most usually; 2, along with the etching of target is more and more darker, the sputter rate of target and the homogeneity of film are all influential, are unfavorable for the deposition of high quality function film; 3, because the existence of the non-etched area of target, insulating material can be deposited on non-etched area surface in coating process, causes a large amount of electronics in last accumulation, thereby causes the target surface starting the arc; Target surface starting the arc the lighter causes the pollution of deposit film, and weight person will cause the unstable of sputter procedure even stop.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, proposes a kind of sedimentary rotary magnetic control sputtering target of large area film that is used for, and improves the utilization ratio of target, avoids the phenomenon of the target surface starting the arc, guarantees the stability of sputter procedure and the quality of deposit film.
For achieving the above object, the utility model proposes technical scheme and be: rotary magnetic control sputtering target, comprise permanent magnet 1, target 4 and rotating mechanism 12, the described target 4 of described rotating mechanism 12 transmissions is around permanent magnet 1 rotation.
Further, described target 4 is the cylindric target of hollow, is fixed with shielding case 5 in the periphery of described column target 4, and described shielding case 5 has the sputter mouth at permanent magnet 1 towards the one side of base material.
Preferably, described permanent magnet 1, target 4 and rotating mechanism 12 all are Controlled twin type.
The beneficial effects of the utility model are: because permanent magnet is fixed in the sputter procedure, and target rotates all the time, so the etching of target is even and etched area is fixed never, can increase substantially the utilization ratio of target like this, reaches more than the 70-80%; Same because whole target surface all is etched, the problem of the non-etched area electronics accumulation of planar target can not occur, thereby avoid the phenomenon of the target surface starting the arc, guarantee the stability of sputter procedure and the quality of deposit film.Because permanent magnet, target and rotating mechanism all are Controlled twin type, the deposited compound film is adopted the intermediate frequency discharge type, increased the homogeneity of deposit film.
Feature of the present utility model and advantage will be elaborated in conjunction with the accompanying drawings by embodiment.
