Definitions
- the present invention relates to a laminated structure and a manufacturing method thereof, and more particularly to a laminated structure including a backing plate and an indium target and a manufacturing method thereof.
- Patent Document 1 a sputtering target is often used by being bonded to a backing plate using indium as a brazing material.
- an indium target if an indium brazing material is used for bonding, both the target and the brazing material are formed of indium, which causes a problem of melting the target itself. Therefore, in the case of an indium target, conventionally, a casting method in which a mold is placed on a backing plate and directly cast, or bonding using a special adhesive has been used, but if a special adhesive is used, the adhesion rate May not be sufficient, and defects may occur during sputtering. Therefore, in the bonding of an indium target, an indium-tin alloy having a melting point lower than that of indium is sometimes used as a bonding brazing material.
- the difference between the melting points of the indium target and the indium-tin brazing material is about 35 ° C., and the melting point is constantly lowered on the bonding surface due to the diffusion and solid solution of tin.
- the diffusion of tin to the indium target side becomes very fast, and the indium target has a problem that tin diffuses from the backing plate side surface to a thickness range of 4 mm.
- the diffusion of tin in the vicinity of the region of 3 to 4 mm in the thickness direction from the surface on the backing plate side is reduced to about several tens of wtppm.
- the target thickness is approximately 5 to 20 mm, in this case, tin is contaminated and diffused in a region of 15 to 60% of the target itself.
- an indium film obtained by sputtering an indium target is used in a CIGS (Cu—In—Ga—Se) solar cell, the indium target is required to have a high purity of 4N or higher. In order to maintain such a high purity in an indium target in which tin is contaminated and diffused, sputtering cannot be performed up to the contaminated and diffused region of tin, causing a significant decrease in utilization efficiency.
- an object of the present invention is to provide a laminated structure with good use efficiency in which the diffusion of tin from the indium-tin brazing material to the indium target is satisfactorily suppressed, and a method for manufacturing the same.
- the diffusion rate of tin is temperature dependent.
- the diffusion of tin is 4 mm from the surface of the indium target in the thickness direction. Confirm that it has advanced to the area. For this reason, when bonding an indium target with an indium-tin brazing material, it is desirable to perform it at as low a temperature as possible.
- the inventors have also noted that tin diffusion is affected by temperature and time. Based on such knowledge, the present inventors diligently studied to solve the above-mentioned problems. After the indium target and the backing plate are bonded with an indium-tin brazing material, they are cooled at a predetermined cooling rate. Thus, it was found that diffusion of tin into the indium target can be satisfactorily suppressed.
- a backing plate, an indium-tin brazing material, and an indium target are laminated in this order, and 2. from the surface of the indium target on the indium-tin brazing material side.
- the laminated structure has a tin concentration of 5 wtppm or less in a thickness range of 5 to 3.0 mm.
- the tin concentration in the thickness range of 2.0 to 2.5 mm from the surface of the indium target on the indium-tin brazing material side is 100 wtppm or less.
- the tin concentration in the thickness range of 2.0 to 2.5 mm from the surface of the indium target on the indium-tin brazing material side is 80 wtppm or less.
- the tin concentration in the thickness range of 1.5 to 2.0 mm from the surface of the indium target on the indium-tin brazing material side is 200 wtppm or less.
- the tin concentration in the thickness range of 1.5 to 2.0 mm from the surface of the indium target on the indium-tin brazing material side is 160 wtppm or less.
- Another aspect of the present invention is a method for manufacturing a laminated structure in which a backing plate, an indium-tin brazing material, and an indium target are laminated in this order, and an indium target having a temperature of 120 to 140 ° C., Bonding the backing plate with an indium-tin brazing material, and cooling the bonded backing plate, the indium-tin brazing material, and the indium target at a cooling rate of 2.5 ° C./min or more; , A method for producing a laminated structure.
- the indium target and a backing plate having a temperature higher by 8 to 20 ° C. than the indium target are bonded using an indium-tin brazing material. To do.
- the indium-tin brazing material used in the bonding has a tin concentration of 10 to 60 at%.
- the present invention it is possible to provide a laminated structure with good use efficiency in which the diffusion of tin from the indium-tin brazing material to the indium target is well suppressed and a method for manufacturing the same.
- the laminated structure according to the present invention is configured by laminating a backing plate, an indium-tin brazing material, and an indium target in this order.
- the shape of the backing plate is not particularly limited, but it can be formed in a disk shape having a predetermined thickness and diameter.
- the constituent material of a backing plate is not specifically limited, For example, it can form with metal materials, such as copper.
- the indium-tin brazing material has a function of joining the indium target and the backing plate.
- the indium target undergoes tin diffusion from the indium-tin brazing material when bonded to the backing plate.
- tin is diffused in the laminated structure according to the present invention, but the degree of this diffusion is small by the manufacturing method described later, and the tin diffusion to the indium target is 2.5 mm or less from the surface of the indium-tin brazing material side. Is controlled.
- the diffusion thickness of tin is ascertained from the tin concentration at the relevant location, and if the tin concentration in the thickness range of 2.5 to 3.0 mm from the indium-tin brazing material side surface of the indium target is 5 wtppm or less, The diffusion range is considered to be 2.5 mm or less.
- the diffused tin concentration is sampled for each target thickness and analyzed by ICP. If the analysis thickness is made fine, the diffusion for each thickness can be accurately observed. However, it is preferable to sample by 0.25 mm thickness. A lathe or machining can be used for sampling. From the ICP analysis of the indium pieces sampled in this way, the tin concentration in the thickness range can be analyzed, and the tin diffusion thickness can be obtained. With such a configuration, the laminated structure according to the present invention has a high proportion of the sputterable region and good utilization efficiency.
- the tin concentration at a thickness of 2.5 to 3.0 mm from the surface of the indium target on the indium tin brazing material side is more preferably 1 wtppm or less.
- the tin diffusion thickness of the indium target is more preferably 2.0 mm or less from the surface of the indium-tin brazing material side.
- the tin concentration in the thickness range of 2.0 to 2.5 mm from the surface of the indium target on the indium-tin brazing material side is preferably 100 wtppm or less. According to such a configuration, the region of less than 2.0 mm from the surface of the indium target on the side of the indium-tin brazing material satisfies the purity of 4N, and can be used as a target for CIGS solar cell applications. Compared with the conventional indium target in which the tin concentration exceeds 100 wtppm in the range of 2.5 to 3.0 mm from the brazing material side surface, the use of 6 to 50% when the thickness of the target is 5 to 20 mm The rate can be increased.
- the tin concentration in the region is more preferably 80 wtppm or less.
- the tin concentration in the thickness range of 1.5 to 2.0 mm from the surface of the indium target on the indium-tin brazing material side is preferably 200 wtppm or less. According to such a configuration, it is possible to substantially satisfy the standard of purity 4N on the formed film side. Sputtering causes a speed difference in erosion due to the positional relationship of the magnets within the target plane. Usually, the use ends when the deepest erosion part to be sputtered most reaches the diffusion region. At this time, since the other region does not reach the diffusion region and is sputtered with a purity of 4N or more, if the tin concentration in the thickness range of 1.5 to 2.0 mm is 200 wtppm or less, it is sputtered from the deepest part. It is possible to sufficiently dilute the deposited tin contamination and satisfy the film purity of 4N.
- the tin concentration in the region is more preferably 160 wtppm or less.
- the thickness of the indium-tin brazing material in the laminated structure is preferably 0.05 to 0.5 mm. If the thickness of the indium-tin brazing material is less than 0.05 mm, sufficient adhesion cannot be provided. Even if the thickness of the indium-tin brazing material is more than 0.5 mm, the effect of adhesion and the like is diminished, but since it contains more expensive metal, it is disadvantageous in terms of cost.
- the thickness of the indium-tin brazing material is more preferably 0.1 to 0.4 mm.
- an indium ingot is produced by a melt casting method or the like.
- the indium ingot is processed into a predetermined shape to produce an indium target.
- the raw material indium to be used preferably has a higher purity in order to increase the conversion efficiency of the solar cell to be produced.
- indium having a purity of 99.99% by mass (4N) or more is used. It is desirable to do.
- a backing plate having a predetermined material and shape is prepared, the indium target is heated to 120 to 140 ° C., and the backing plate is further heated.
- an indium-tin brazing material is dissolved on the backing plate and sufficiently spread using a scraper or the like. Similarly, an indium-tin brazing material is applied to the indium target and bonding is immediately performed. Next, the bonded backing plate, the indium-tin brazing material, and the indium target are cooled at a cooling rate of 2.5 ° C./min or more to produce a laminated structure.
- a cooling rate 2.5 ° C./min or more to produce a laminated structure.
- the cooling rate depends on the difference between the temperature of the indium target (T ° C.) and 40 ° C. at which the solid diffusion of tin is sufficiently suppressed (T ⁇ 40 [° C.]). Divide by to find.
- the backing plate for bonding with the indium target is set to 8 to 20 ° C. higher than the indium target. Suppresses irregular solidification of the brazing material that often occurs during bonding, and even if it occurs itself, it immediately dissolves and recovers, enabling good bonding, and improving the adhesion rate between the target and the backing plate. It can be 90% or more.
- the temperature of the backing plate is more preferably heated to a temperature that is 10 to 15 ° C. higher than the indium target.
- the tin concentration of the indium-tin brazing material used for bonding is preferably 10 to 60 at%. With such a configuration, a temperature difference between the indium target having a low melting point and the brazing material can be sufficiently provided for practical use, and good bonding is possible.
- the tin concentration is preferably 20 to 55 at% in order to increase the temperature difference.
- the laminated structure thus obtained can be suitably used as a sputtering target for the light absorption layer for CIGS thin film solar cells.

Abstract
Description
このような知見に基づき、本発明者らは上記課題を解決するために鋭意検討したところ、インジウムターゲットとバッキングプレートとをインジウム-錫ロウ材でボンディングした後、それらを所定の冷却速度で冷却することで、錫のインジウムターゲット内への拡散を良好に抑制することができることを見出した。
本発明に係る積層構造体は、このような構成により、スパッタ可能な領域の割合が多く、利用効率が良好である。インジウムターゲットのインジウム錫ロウ材側表面から2.5~3.0mmの厚みにおける錫濃度は1wtppm以下であることがより好ましい。また、インジウムターゲットの錫拡散厚みは、インジウム-錫ロウ材側表面から2.0mm以下であることがより好ましい。
まず、溶解鋳造法等でインジウムインゴットを作製する。続いて、このインジウムインゴットを所定の形状に加工してインジウムターゲットを作製する。この際、使用する原料インジウムは、作製する太陽電池の変換効率を高くするために、より高い純度を有していることが望ましく、例えば、純度99.99質量%(4N)以上のインジウムを使用することが望ましい。
次に、所定の材料及び形状のバッキングプレートを用意して、インジウムターゲットを120~140℃に加熱しておき、さらにバッキングプレートを加熱しておく。十分に定常状態となった後、まずバッキングプレート上にインジウム-錫ロウ材を溶解させて、スクレーパー等を用いて十分に塗り広げる。インジウムターゲットも同様にインジウム-錫ロウ材を塗り、直ちにボンディングを行う。
次に、ボンディングされたバッキングプレート、インジウム-錫ロウ材、及び、インジウムターゲットを2.5℃/分以上の冷却速度で冷却することで、積層構造体を作製する。
このような構成により、インジウムターゲットへの錫の拡散の抑制が可能となる。これは、物質の拡散が温度、時間の影響を受けるためである。
インジウムターゲットの温度は125~135℃とすることがより好ましい。
冷却速度は4℃/分以上とすることがより好ましい。冷却速度はインジウムターゲットの温度(T℃)と、錫の固層拡散が十分に抑制されると考えられる40℃との差(T-40〔℃〕)を、冷却に要した時間(分)で除して求める。
また、上記ボンディング工程において、インジウムターゲットとボンディングするバッキングプレートをインジウムターゲットより8~20℃高く設定しておくことが好ましい。ボンディング時にたびたび発生するロウ材のイレギュラーな凝固を抑制し、仮にそのような自体が発生した場合にも直ちに最溶解、回復され、良好なボンディングが可能となり、ターゲットとバッキングプレートとの接着率を90%以上とすることができる。バッキングプレートの温度はインジウムターゲットより10~15℃高い温度に加熱するのがより好ましい。また、このような温度差の設定を上記ボンディング法と組み合わせることで高い接着率と錫拡散の低減の両立が可能となる。
ボンディングで使用するインジウム-錫ロウ材の錫濃度は10~60at%であることが好ましい。このような構成により、低融点であるインジウムターゲットとロウ材の温度差を実用上十分に設けることができ、良好なボンディングが可能となる。錫濃度は温度差をより大きくするため20~55at%が好ましい。
まず、純度4Nのインジウムを原料として使用し、このインジウム原料を160℃で溶解させ、この溶体を周囲が直径205mm、高さ7mmの円柱状の鋳型に流し込み、自然冷却により、凝固して得られたインジウムインゴットを直径204mm、厚さ6mmの円板状に加工して、スパッタリングターゲットとした。
次に、直径250mm、厚さ5mmの銅製のバッキングプレートを準備した。
次に、バッキングプレートを表1に記載の温度Aに加熱し、インジウムターゲットを表1記載の温度Bで加熱した状態で、表1に記載の錫濃度のインジウム-錫ロウ材をバッキングプレート、インジウムターゲットの順に塗り広げ、ただちにバッキングプレートとインジウムターゲットとをボンディングし、次に表1に記載の冷却速度で冷却することにより積層構造体を作製した。
実施例及び比較例で得られた積層構造体のインジウムターゲットについて、インジウム-錫ロウ材側表面から厚み方向へかけて、厚みごとにマシニングにより切削、回収し、錫濃度をそれぞれICP分析法で測定した。
また、これら実施例及び比較例で得られた積層構造体のインジウムターゲットとバッキングプレートとの接合状態(接着率)を電子走査式超音波探傷器で測定した。具体的には、ターゲットを当該装置の探傷器水槽内にセットして、周波数帯域1.5~20MHz、パルス繰返し周波数5kHz、スキャンスピード60mm/minで測定し、得られた像イメージから、接着領域が全体領域に占める割合を算出し、接着率として表した。
各測定条件及び測定結果を表1に示す。
比較例1~5は、いずれもボンディングされたバッキングプレート、インジウム-錫ロウ材、及び、インジウムターゲットを冷却する速度が2.5℃/分未満であったため、インジウム-錫ロウ材からインジウムターゲットへの錫の拡散が大きかった。
比較例6及び7は、ボンディング工程におけるインジウムターゲットの温度が120~140℃の範囲外であったため、インジウム-錫ロウ材からインジウムターゲットへの錫の拡散が大きかった。
