Definitions
- the invention relates to a sputtering target with a metal oxide sputtering material, the sputtering material comprising zirconium and titanium as the metal.
- Such sputtering targets are well known, for example from WO 201 1/1 10584 A1. They are used for example for the production of coatings on glass. Sputtering targets made of a mixture of titanium dioxide and zirconium dioxide are used. Amongst other things, sputtering targets of such compositions have the disadvantage that they may have larger accumulations of nonconducting zirconia, which tend to sparks undesirably (so-called arcing), which impairs the quality of the sputtering process and the resultant coating.
- the object of the present invention is to eliminate the disadvantages known from the prior art.
- the object is solved by the subject matter of the independent claim.
- Preferred embodiments are specified in the dependent claims.
- the proportion of the mixed oxide phase in the sputtering target is at least 30% by weight, preferably at least 50% by weight and in particular at least 70% by weight, based on the total weight of the sputtering material.
- mixed oxides of zirconium and titanium do not have any interfering nonconductive structures. The higher the proportion of the mixed oxide phase, the better the sputtering behavior of the sputtering targets.
- the proportion of the mixed oxide phase in the sputtering target is expediently at least 95% by weight, based on the total weight of the sputtering material. It is furthermore advantageous that the proportion of zirconium dioxide phases is at most 5% by weight, based on the total weight of the sputtering material. Such small amounts of Zirkoniumdioxidphasen no longer detect spurious sparking.
- the proportion of zirconium in the metal fraction amounts to 20 to 30% by weight. Here, good coating results were achieved.
- the sputtering material has an oxygen deficit compared to the stoichiometric composition, since this improves the conductivity of the material.
- the sputtering material can be produced by melting two metal oxides together in a known manner.
- the zirconia used as starting material may be stabilized in the usual way (for example with yttrium oxide or calcium oxide).
- the melting of the starting materials titanium dioxide and zirconium dioxide can preferably take place under reducing conditions, so that the resulting sputtering material has an oxygen deficit (oxygen substoichiometry).
- the sputtering material can contain other metal components (for example hafnium) which are unavoidable in industrial quality or the abovementioned stabilizing materials, which frequently occur to a small extent below about 10% by weight.
- metal components for example hafnium
- stabilizing materials which frequently occur to a small extent below about 10% by weight.
- a mixture of 60% by weight of titanium dioxide and 40% by weight of zirconium dioxide can be melted together. Also a sintering is possible.
- the resulting mixed oxide is ground and can then be applied to a carrier structure of the sputtering target by an injection process, for example plasma spraying.
- the support structure may be a conventional carrier tube or a likewise conventional carrier plate.
- the mixed oxide powder has a particle size of about 10 to 90 ⁇ .
- the melt metallurgy or sintering processes used in the manufacture are generally conventional and known to those skilled in the art.
- a powder was prepared with a mixture of 80 wt .-% Ti0 2 and 20 wt .-% Y 2 0 3 stabilized Zr0 2 .
- the powder was then sintered at 1400 ° C for 4 h and then classified to a sprayable particle size.
- the processing into a tube target is carried out as in Example 1 by plasma spraying with an Ar / H 2 plasma.
- the sputtering targets according to the invention produce very uniform layers with at most a few structure defects which do not interfere with the formation of sparks.
