Description of the Invention: [Technical Field of the Invention] The present invention relates to a support plate, a dry material assembly, and a thick material for a splashing clock which are highly drinkable to a joint material (weld material). [Prior Art] As for the technique of forming a thin film on a substrate, a hydrazine chain method is known. Since the material for the extinguishing element is heated by the action of ions in the electric destruction, it is used in a state of being joined to the support plate for cooling. Brazing is widely used for bonding the lightweight material of the support plate. The target used in sputtering is required to withstand the temperature rise or thermal stress during film formation, and the amount of released gas is small. In particular, the heat resistance of the target requires high adhesion to the target and the support plate. Therefore, the target and the support plate are required to have sufficient wettability with the welding material, and the metal is conventionally used for the underlayer treatment of the joint surface between the target and the support plate by metal, vapor deposition, and flux. Metallized processing (see, for example, Patent Document 1). [Prior Art Document] (Patent Document) Patent Document 1: JP-A-2006-257510 SUMMARY OF INVENTION [Problems to be Solved by the Invention] However, by metallization treatment of plating, vapor deposition, or fluxing, Since the surface of the base material is coated with the metallized layer, the adhesion to the base material is poor, and there is a problem of peeling. In addition, the metallization process by plating or flux application requires the disposal cost of waste liquids while the environmental load is very large 4 323678 201226613. Further, the flux has a problem of releasing gas, and it is difficult to form a film of high quality. In view of the foregoing, it is an object of the present invention to provide a connection. A support plate, a target assembly, and a target for sputtering which are excellent in adhesion. [Means for Solving the Problems] In order to achieve the above object, a support plate according to an aspect of the present invention includes a support plate main body and an adhesion layer. The support plate body has a first surface facing the sputtering target and is formed of a first metal material. The adhesion layer has a second surface coated with a bonding material formed of an alloy of indium, tin or the like, and includes a second metal material having higher wettability with respect to the bonding material than the first metal material. And formed on the first surface. Further, a target assembly according to an aspect of the present invention includes a target for sputtering, a support plate body, a bonding layer, and an adhesion layer. The support plate system includes a first surface facing the material and is formed of a first metal material. The bonding layer is provided between the target and the first surface, and is formed of a bonding material. The adhesion layer includes a second surface to which the bonding material is applied, and a second metal material having higher wettability with respect to the bonding material than the first metal material, and the first surface is formed. Further, the target for sputtering according to one embodiment of the present invention includes a target body and a metallization layer. 5 323678 201226613 The above-mentioned material-incorporated system is provided with a joint surface coated with a bonding material formed of indium, tin or an alloy thereof, and is formed of a second metal material. The metallization layer is formed on the joint surface and is composed of an alloy phase of the second metal material and the second metal material, and the second metal material is higher than the first metal material for the joint material. Wettability. [Embodiment] [Best Mode for Carrying Out the Invention] A support plate according to an embodiment of the present invention includes a support plate main body and an adhesive layer. The support plate system has a first surface facing the sputtering target and is formed of a first metal material. The adhesion layer includes a second surface material coated with a bonding material made of an alloy of indium, tin or the like, and includes a second metal material having higher wettability with respect to the bonding material than the first metal material. And formed on the first surface described above. In the above-mentioned support plate, since the adhesive layer is formed of a material having a higher wettability with respect to the constituent material of the support plate body, a high adhesion can be obtained between the adhesive layer and the joined material. The adhesion layer may be formed of a metallization layer formed by an alloy phase of the first metal material and the second metal material. Thereby, the metallized layer can be integrated with the first surface of the support plate body, and the metallized layer can be prevented from being peeled off from the first surface. Further, since the above-mentioned alloy phase contains a metal material having high wettability to the bonding material, it is possible to provide adhesion to the bonding material of 6 323 678 201226613 liter. The first metal material and the second metal material forming the metallization layer of the support plate are not particularly limited and may be arbitrarily selected. For example, examples of the first metal material include copper, indium, titanium, copper, or the like, or stainless steel. Examples of the second metal material include copper, nickel, aluminum, and tin. , indium, gold, silver, or alloys of these. Among them, for example, the first metal material is molybdenum or an alloy thereof, and the second metal material is a combination of nickel or an alloy thereof. The method of forming the above metallization layer is also not particularly limited. For example, the metallization layer can be formed by discharge treatment. Thereby, the metallized layer can be easily formed. The adhesion layer may be formed of a metal plate formed of the second metal material and joined to the first surface. The metal plate is joined to the first surface of the support plate body to form a metallization layer of the support plate body. Since the metal plate is formed of a material having a more southergic property to the material of the support plate than the material of the support plate, high adhesion can be obtained between the metal plate and the joint material. Further, since the metal plate is integrally joined to the support plate body, a high peeling strength to the support plate body can be obtained. The joining method of the metal plate to the support plate body is not particularly limited, and for example, explosive joining, diffusion bonding, welding, or the like can be applied. Thereby, it is possible to avoid the problem of disposal of waste liquid or generation of gas. The first metal material forming the support plate main body and the second metal material forming the metal plate are not particularly limited and may be arbitrarily selected. For example, in the case of the first 323678 201226613 metal material, it is possible to use: Ti (titanium), Ti alloy or stainless steel, and for the second metal material, it can be used: Cu (copper), Ni (recorded), A1 (aluminum) Or such alloys. Since the support plate made of Ti (titanium), Ti alloy or stainless steel as a base material has a large Young's modulus and high strength, the expansion due to water pressure is small. Therefore, such a support plate is used, for example, in a target which is highly brittle in sintering. Since the thermal expansion coefficient of the niobium and the Ti alloy is small, the support plate using the material as the substrate is, for example, ITO (Indium Tin 〇xide; indium tin oxide), GZ 〇 (Gallium-doped Zinc Oxide; gallium zinc oxide ()) used in low thermal expansion dryness. Since Ti, Ti alloy and stainless steel are low in wettability due to bonding with 1η (indium) or Sn (tin) due to your τ γ 螂, a metal plate formed of Cu, Ni, M, etc. is formed. The joint surface* ensures good adhesion to the above-mentioned joining material. The metal plate may be divided into a plurality of divided pieces and connected to the first surface. Thereby, warping or deformation of the support plate due to the difference in the coefficient of expansion of the support plate body and the plate can be suppressed. The present invention is an embodiment of the present invention, which comprises a dry material for splashing money, a support plate body, a joint layer, and an adhesive layer. The above-mentioned support plate system is formed to face the above-mentioned series and is formed of a first metal material. Further, the bonding layer is formed on the bonding material of the material and the i-th surface. The adhesion layer has a second surface coated with the bonding material, and contains a metal material of the first 323678 8 201226613 which is more sturdy to the bonding material (4), and is formed on the first surface. In the above dry material assembly, the adhesion layer is formed of a material having a higher wettability to the bonding material than the constituent material of the support plate body. Therefore, high adhesion can be obtained between the material and the material. A target for sputtering according to an embodiment of the present invention includes a target body and a metallization layer. The above target system has a joint surface coated with a bonding material formed of indium, tin or an alloy thereof, and is formed of a first metal material. The metallization layer is formed on the joint surface and is composed of an alloy phase of the first metal material and the second metal material, and the second metal material has a higher pressure than the first metal material for the joint material. Wet. The metallization layer is composed of an alloy phase of the first and second metal materials. Thereby, the joint surface of the metallized layer and the target body can be integrated, and the metallized layer can be prevented from peeling off from the joint surface. Further, since the above alloy phase contains a metal material having high wettability to the bonding material, the adhesion to the bonding material can be improved. The first metal material and the second metal material forming the metallization layer of the target are not particularly limited and may be arbitrarily selected. For example, examples of the first metal material include copper, aluminum, titanium, molybdenum, or an alloy thereof, or stainless steel. Examples of the second metal material include copper, nickel, aluminum, and tin. Indium, gold, silver, or alloys of these. Among them, a combination of, for example, a first metal material of ruthenium or an alloy thereof and a second metal material of nickel or an alloy thereof can be suitably used. 9 323678 201226613 Hereinafter, embodiments of the present invention will be described with reference to the drawings. <First Embodiment> [Dry Material Assembly] Fig. 1 is a cross-sectional view schematically showing a target assembly according to an embodiment of the present invention.

The target assembly 10 is provided in a sputtering apparatus (not shown). The support plate 1 is connected to a direct current, alternating current or RF power source, and the target 2 is disposed to face the substrate surface in the vacuum chamber at a predetermined interval. The target assembly 10 has a structure cooled by, for example, cooling water, and the water-cooled support plate 1 prevents excessive temperature rise of the target 2 at the time of the money, and prevents peeling of the target 2 due to melting of the bonding layer 3. Wait. The target assembly 10 is combined with a magnetic field unit (not shown) to constitute a magnetron type cathode-extinguishing cathode. [Support Plate] Fig. 2 is a cross-sectional view of the support plate 1. The support plate 1 has a metal support plate body 11 and a metallization layer 12 (first metallization layer). The support plate body 11 has a joint surface 11a. The target 2 is joined to the joint surface 11a via the joint layer 3.

Further, the support plate body u is not limited to the case of the shape: water contact, and for example, as shown in Fig. 3, it may be a plate-shaped cross-sectional shape called Tian Pingchun. The hat-shaped metallization layer 12 is formed on the joint surface 11a, the metal J constitutes a base material (first metal material) of the support plate main body 11, and the layer 12 is bonded to the layer 3 (in, Sn, etc.) a higher wettability than the metal phase of the metallized metal (second metal material) of the metal material, which serves as a lifting support body Η and a bonding layer / 'metallization layering' The function of the close layer. In the case of the adhesion between the bonding material such as In, Sn, etc., it may be exemplified by Cu, Ni, Al, Sn, ln, Au, a metal material, and gold, in order to constitute the metal of the support plate body 11. The material type g or the combination of the above is in the embodiment, and the support plate main body 11 is appropriately selected from the household. Ni is used for the metal system. Fig. 4 illustrates a method of forming the metallization layer 12, and the formation layer 12 is formed by discharge treatment. As shown in the diagram of Figure 4. The metal electrode rod 15 is pinned to the joint surface 1 by a predetermined gap, and the rod 15 for discharge is made of a metallized metal (in this example, the Ni_a phase is arranged in a fresh direction. When the metallized metal of the electric Ua is processed, By applying a predetermined voltage between the joint faces 11, a discharge is generated between the electrode rods 15 and the support plate surface 11a. Thereby, the front end and the joint of the joint faces are formed by The Ni particles scattered from the electrode rod 15 and the gold base material (M〇) are moved on the joint surface 11a, whereby the metal 201226613 layer 12 is formed on the entire surface of the joint surface 15 of the electrode rod 15 system 3. The metallization metal treatment conditions of 11a are not particularly limited, and for example, a pulse power source having a voltage of 150 V and a capacitor capacity of 4 〇 eF or a pulse power source having a voltage of 100 V and a capacitor capacity of 10 Å can be used as a power source. The thickness of the metallization layer 12 is It is not particularly limited as long as the surface layer of the joint surface 11a can be metalized. Since the metallization layer 12 is integrally formed with the joint surface 11a of the support plate main body 11, the metallization layer 12 is prevented from being peeled off from the joint surface 11a. In addition to the composition of gold Since the alloy phase of the layer 12 contains a metal material (metallized metal) having high wettability with respect to the bonding material, adhesion to the bonding material can be improved.

Therefore, Ti, Ti alloy or stainless steel is used as the support plate of the substrate, and the expansion due to the water pressure is small. Therefore, for example, a high-brittle target such as a sintered target uses such a support plate. Further, since the thermal expansion coefficients of the Ti and the Ti alloy are small, these materials are used as a support plate for the substrate, and are used, for example, in ΙΤ0. (Indium Tin idexide; indium tin oxide), GZ 〇 (Gallium-doped Zinc Oxide; gallium zinc oxide) and other targets with small thermal expansion. The support plate main body 311 has a circulation path of cooling water (not shown) inside. The support plate main body 311 is not limited to the structure having the above-described circulation passage therein, and may be a cooling surface that is in contact with the cooling water on the surface opposite to the joint surface 31a. Further, the support plate main body 311 is not limited to the example in which a simple plate shape is formed, and may be a cross-sectional shape called a hat type as shown in Fig. 8. The metal plate 312 has a joint surface 312a (second surface). The joint surface 312a is formed on the opposite side of the surface opposite to the support plate body 311. A bonding material constituting the bonding layer 33 is applied to the bonding surface 312a. The metal plate 312 is joined to the joint surface 311a to constitute a metallization layer of the support plate body 311. The metal plate 312 is a metallized metal (second metal) having a metal substrate (first metal material) constituting the support plate main body Mi and a bonding material Sn constituting the bonding layer 33, etc., which is more wettable than the metal material. Material). The metal plate 312 functions as an adhesive layer for improving the adhesion between the support plate main body and the bonding layer 33. The thickness of the metal plate 312 is not particularly limited, and is, for example, 〇. For metal materials having high wettability for bonding materials such as In and Sn, 323678 15 201226613, for example, Cu, Ni, μ, Sn, In, Au, Ag, or the like, may be cited, and the support plate body 3U is constituted. The type of metal material is appropriately selected. In the present embodiment, the metal plate 312 is formed of Cu, Ni, A1 or the like. In the present embodiment, the constituent material of the support plate main body 311 is Ti, a Ti alloy or stainless steel. Since Ti, Ti alloy, stainless steel, and the like have low wettability with a bonding material such as in or Sn, the metal plate 321 formed of Cu, Ni, A1 or the like is formed on the bonding surface 3Ua, thereby ensuring good adhesion to the bonding material. Sexuality. The method of joining the metal sheets to the support plate body is not particularly limited, and in the present embodiment, the explosion bonding method is employed. Explosive bonding is a method in which the high-volume generated in a very short period of time when a gunpowder breaks out is used in gold; the method of joining between s, also known as burst fusion or burst crimping. Fig. 9 is a view showing a method of joining the support plate body and the metal plate 312 by an explosion joint. As shown in Fig. 9(A), a metal plate 312 is disposed opposite to the joint surface 311a of the support plate main body 311. On the back side (upper side in the figure) of the metal 312, a gunpowder layer 342' is disposed via a cushioning material 341, and a detonator 343 is attached to one end (left end in the drawing) of the gunpowder layer 342. As shown in Fig. 9(B), the detonator 343 is detonated and the gunpowder layer 342 is sequentially ejected to the right in the figure. The metal plate 312 is formed at a predetermined angle to collide with the joint surface 311a, and the oxide film or the like on the metal surface is removed by the metal jet generated from the collision point. The surfaces of the metal plate 312 and the joint surface 311a are sequentially joined to each other from the collision point in the above manner. In the joining step of the support plate main body 311 and the metal plate 312, other solid phase joining methods such as a friction bonding method or a diffusion bonding method may be employed in addition to the above-mentioned 323,678, 2012, 2012, and the welding method using a welding material may be employed. [Target] (4) 32 may be a cast body of a raw material metal or a sintered body of a raw material powder. The dry material 32 of the present embodiment is formed of a sintered body made of a transparent conductive oxide such as ιτ〇 or (10). (4) 32 series points Suitable for the size, thickness, shape and structure of sputtering applications. The support plate 31 and the dry material constituting the ruthenium are adhered to each other in a state in which the respective operating surfaces are opposed to each other via a joining material in a molten state. At this time, the joint surface on the side of the support plate 31 is covered by the gold plate 312 which is made of a material having a higher wettability with respect to the constituent material of the support body 311, so that it can be secured at the joint surface 312 & Good wettability of the whole domain and the joint material. The bonding layer 33 is formed by hardening a bonding material. According to the above embodiment, it is possible to obtain good adhesion between the support plate 31 and the bonding layer 33. Further, since the metal plate 312 and the support plate body 311 are physically joined, a high peeling strength can be obtained for the support plate body 311. Further, according to the present embodiment, since the metal plate 312 forming the metallization layer is integrally joined to the support plate main body 311, it is different from the electric bond or the grafting agent treatment, and the waste liquid treatment is required, and the load on the environment is also small. In addition, since there is no problem of gas evolution, a high-quality shovel film can be formed. Further, according to the present embodiment, since the support plate main body 311 is formed of Ti having a small thermal expansion coefficient, the warp or deformation ratio due to heat is small. Therefore, even if the target material 32 is a material having high brittleness like the IT 〇 sintered body, 323678 17 201226613 does not cause cracking or cracking, and the dry material 32 can be stably maintained. According to the estimation by the inventors of the present invention, in a plate-shaped support plate having a width of 200 mm, a length of 3000 fflin, and a thickness of 16 mni, a target assembly of an ITO target having a width of 200 mm, a length of 2700 mm, and a thickness of 8 mni is bonded, and a Cu-made support plate is used. 0毫米左右。 The amount of warpage of the target of the support plate of the support plate can be reduced to 1. 0mm. The embodiments of the present invention have been described above, but the present invention is not limited to the embodiments, and various modifications can be made based on the technical idea of the present invention. For example, in the above embodiments, the support plate wires are each formed of the same metal material, but the present invention is not limited thereto, and may be formed of a different metal material. Further, the alloy phase constituting the metallization layers 12 and 22 is not limited to an alloy of a base material and a metallized metal, and may be a mixed phase or a compound phase, or a metallized metal single phase. Further, the metal plate 312 is joined to the entire area of the joint surface of the support plate main body 311. However, the metal plate 312 may be joined to a portion of the joint surface 31 as shown in Fig. 3 . Further, the U-shaped (fourth) metal plate 312 may be formed into a plurality of t-cut pieces m and joined to the joint surface 31a. Thereby, the shape or size of each of the divided pieces 12 m of the support plate caused by the difference in thermal expansion coefficient between the support plate body 311 and the metal plate 312 can be called.
