Definitions
- the present invention relates to a sputtering target assembly, particularly a sputtering target assembly for FPD, for reducing defects due to generation of particles caused by piece bonding portions.
- Thin films such as ITO, ZnO-based, In 2 O 3 —ZnO-based, and MgO-based thin films for forming transparent conductive films are widely used as transparent electrodes in display devices such as liquid crystal displays, touch panels, and EL displays.
- an oxide thin film for forming a transparent conductive film such as ITO is formed by sputtering.
- an in-line type sputtering apparatus has been used for forming a transparent conductive film for a large FPD (flat panel display).
- FPD flat panel display
- target plates having a width of 150 to 300 mm and a length of 1500 mm or more are used.
- Several sheets are arranged and a large glass substrate moves in front of the target to form a film.
- a single target-backing plate assembly is obtained by laminating target pieces that are divided into several lengths on the backing plate. Generally, a plurality of these are arranged in the width direction to increase the size.
- this target-backing plate assembly can be increased in size by arranging in the width direction, but the target piece divided into several in the length direction is between the target pieces of the adjacent target-backing plate assembly.
- the dividing lines will be aligned. There is a gap between the target pieces in this dividing line, and the height of each target piece is slightly different, so there is a step at the dividing line, so nodules are generated during sputtering from this dividing line. It is easy to cause a portion where a large amount of dust called particles are attached on the film to form a streak, resulting in a decrease in yield.
- target pieces of the same dimensions are manufactured and bonded together on a backing plate.
- the target pieces are neatly aligned and look good at first glance, Since all the dividing lines between the two pieces are aligned, nodules are concentrated on the aligned target piece portions. As a result, the adhesion of dust called particles on the film is concentrated on a specific position, resulting in a decrease in yield. .
- problems have been overlooked for a long time without becoming obvious because the focus was on improving the productivity of the target itself and the production volume of large FPDs was still small. As the production amount of FPD increases, such film formation defects frequently occur, and there have been cases where the productivity actually decreases.
- a large rectangular target plate is composed of a target assembly composed of a large number of tiles, and each tile is configured to merge with a gap of three or less tiles, Preventing tile misalignment during thermal cycling is described.
- it may be rectangular, square, hexagonal or fan-shaped.
- This document 1 aims to arrange a large number of tiles closely so that they do not shift, and no measures are taken to prevent generation of nodules during sputtering and particles on the film. 6, FIG. 7, FIG. 8, FIG. 9, and FIG. 10 showing specific examples of the target assembly of this document 1, at least every other tile, and the tile joints are aligned. .
- Such a target assembly results in nodule generation during sputtering and an increase in particles on the film.
- Patent Document 2 describes a disk-shaped divided target, which is composed of a circular divided piece at the center and four fan-shaped divided pieces (having a lack of the central portion) in the periphery. Proposals have been made in which a step is provided at the joint portion of each of the divided pieces for joining. Such a disk-shaped split target is not suitable for manufacturing a target assembly for a large FPD (flat panel display). In addition, every other split target of Document 2 has tile joints aligned. As a result, the target having such a structure has problems that cause nodules during sputtering and increase the number of particles on the film.
- Patent Document 3 describes a disk-shaped divided target, which is composed of a circular divided piece at the center and two fan-shaped divided pieces (having a lack of the central portion) at the periphery. Proposals have been made to cut the joints of the divided pieces and join them obliquely.
- Such a disc-shaped split target is not suitable for manufacturing a target assembly for a large FPD (flat panel display), as in the case of the above-mentioned document 2.
- every other split target of Document 3 has tile joints aligned.
- the target having such a structure has problems that cause nodules during sputtering and increase the number of particles on the film.
- JP 2006-22404 A Japanese Patent Laid-Open No. 5-263234 JP-A-5-17867

- the present invention also provides: In one sputtering target-backing plate assembly B, there is provided a sputtering target assembly as described in 1) above, wherein the difference in length of each divided target piece A is 100 mm or more.
- the present invention also provides:
- the dividing line between the target pieces of one sputtering target-backing plate assembly B and the dividing line between the target pieces of the adjacent sputtering target-backing plate assembly B are parallel, and the parallel spacing between the adjacent dividing lines is The sputtering target assembly according to any one of 1) to 3) above, wherein the sputtering target assembly is 50 mm or more.
- the present invention also provides: The dividing line between the target pieces of one sputtering target-backing plate assembly B and the dividing line between the target pieces of the adjacent sputtering target-backing plate assembly B are parallel, and the parallel interval between the adjacent dividing lines is 100 mm.

- FIG. 3 is a diagram showing a state of generation of particles when a film is formed using a sputtering target assembly composed of a sputtering target-backing plate assembly of Example 1.
- FIG. 4 is a diagram showing a state of generation of particles when a film is formed using a sputtering target assembly composed of a sputtering target-backing plate assembly of Comparative Example 1. It is a figure which shows the example which joined three target pieces with the same width
- the sputtering target assembly of the present invention divides a rectangular target whose one target is 100 mm or more in width and 1000 mm or more in length into three or more target pieces A so that the dividing line is in the width direction, A sputtering target assembly in which the divided target pieces A are laminated on a backing plate in the length direction to form a sputtering target-backing plate assembly B, and three or more assemblies B are aligned in the width direction.
- the dividing line between the three target pieces existing in the joined body B is not located at the same position as the dividing line between the adjacent divided target pieces.
- Sputtering target assembly to be installed can also be referred to as a target assembly characterized by a sequence structure of target (target piece).
- target piece This is suitable as a sputtering target for FPD and satisfies the main requirements of a large-sized sputtering target assembly that can reduce the generation of particles and improve the yield.
- FIG. 3 shows a representative example in which three target pieces A1, A2, and A3 having the same width and different lengths are mounted on a backing plate.
- a dividing line exists between the target pieces A1, A2, and A3. This dividing line is a gap that can be created because the target pieces are produced separately.
- the target-backing plate assembly in which the lengths of the target pieces are changed and the dividing lines between the target pieces when the targets are arranged are combined so that they are displaced, It is possible to improve the yield by dispersing particles resulting from the portion.
- the length difference of each divided target piece A can be set to 50 mm or more, and further to 100 mm or more.
- the sputtering target assembly of the present invention can achieve this. This is because the target pieces are combined so that the joining positions of the target pieces are shifted as much as possible.
- the dividing line between the target pieces of one sputtering target-backing plate assembly B and the dividing line between the target pieces of the adjacent sputtering target-backing plate assembly B are parallel. It is desirable that the parallel interval between the adjacent joining positions be 50 mm or more, and more preferably 100 mm or more. This is also because the joining positions of the target pieces are combined as much as possible without being aligned.
- the divided target used for three or more rectangular target pieces A can be composed of three or more types of divided targets having the same dimensions. From the viewpoint of target productivity, it can be said that the target piece A having the same shape is desirable. This is because the production of the irregularly shaped target piece causes the production cost to increase.
- the present invention proposes that there are three or more types as described above, but these are all rectangular and have the advantage of not causing complexity and an increase in manufacturing cost as shown in the above-mentioned patent document. .
- the target piece A having the same shape has an advantage that only three types are required. As shown in the examples to be described later, three types of rectangular target pieces A, rectangular target pieces A1, A2, and A3 having different dimensions are prepared, and these are arranged on a backing plate and joined together. As an example, an array of target pieces A1, A2, and A3, an array of combinations thereof, an array of target pieces A3, A1, and A2, and an array of combinations of the target pieces A2, A3, and A1 are possible.
- the dividing lines between the target pieces do not align due to the positional relationship with the adjacent sputtering target-backing plate assembly.
- the target piece A having the same shape requires at least three kinds, and the manufacturing cost can be reduced.
- the target pieces are combined as one of the combinations.
- Example 1 A 200 mm ⁇ 1500 mm target plate is bonded to a backing plate as shown in FIG. 1 by laminating pieces having a length of 300 mm, 500 mm, and 700 mm to produce three types of sputtering target-backing plate assemblies. As shown in the figure on the left side of FIG. 1, the combination of the sputtering target and backing plate assembly is set to X, Y, and Z so that the dividing line between the target pieces is shifted when three sets are arranged. Thus, a sputtering target assembly was obtained. This X, Y, Z set can be repeated as needed.
- each target is produced by bonding pieces of the same size, so several of these targets are produced.
- the dividing lines between the target pieces are arranged (aligned) at the same position, and when the film is formed, the particles are concentrated in the vicinity of the position and the product yield is lowered.
- the present invention can solve this problem, and when the length of the target piece A is changed and the sputtering target-backing plate assembly is arranged as described above, the dividing line between the target pieces is shifted between the targets. In combination, particles resulting from the dividing line between the target pieces can be dispersed and the yield can be improved.
- FIG. 2 shows the target-backing plate assembly in which target pieces of the same size are arranged on the backing plate and the state of generation of particles. As shown on the right side of FIG. 2, the number of particles in the region corresponding to the dividing line between the target pieces was as high as 28 and 29, and this region could not be used as a product.
- a bonded body B formed by pasting a plurality of rectangular pieces A on each backing plate to form a joined body B.

Abstract
Description
この様な大きなターゲットを一枚物のターゲット板として作製することは困難であるため、通常、長さ方向に数分割したターゲットピースをバッキングプレート上で張り合わせて単一のターゲット-バッキングプレート接合体とし、これをさらに複数個、幅方向に整列させて大型化するのが一般的である。
従来は、ターゲット自体の生産性向上に注力していたことと、大型FPDの生産量が未だ少なかったために、このような問題は、顕在化することなく長い間見落とされていたが、近年、大型FPDの生産量が増大するにつれ、このような成膜不良が多く生じるようになり、実際に生産性の低下につながる事例が発生するようになっていた。
この文献1では、多数のタイルを密に配置し、それらが位置ずれしないようにすることが目的であり、スパッタリング中のノジュール発生や膜上のパーティクルを防止するための対策は採られていない。この文献1のターゲット組立体の具体例を示す図6、図7、図8、図9、図10のいずれを見ても、タイルは少なくとも一つ置きに、タイルの接合部が整列している。このようなターゲット組立体は、結果としてスパッタリング中のノジュール発生や膜上のパーティクルを増加させる原因となる。
また、文献2の分割ターゲットは一つ置きに、タイルの接合部が整列している。このような構造を持つターゲットは、結果としてスパッタリング中のノジュール発生や膜上のパーティクルを増加させる原因となる問題を有している。
また、文献3の分割ターゲットは一つ置きに、タイルの接合部が整列している。このような構造を持つターゲットは、結果としてスパッタリング中のノジュール発生や膜上のパーティクルを増加させる原因となる問題を有している。
1)幅100mm以上、長さ1000mm以上である矩形のターゲット板として、分割線が幅方向になるように3個以上のターゲットピースAに分割されており、この分割ターゲットピースAを、長さ方向にバッキングプレート上に張り合わせてスパッタリングターゲット-バッキングプレート接合体Bを構成し、さらにこの接合体Bを幅方向に3個以上整列させたスパッタリングターゲット組立体であって、各個の接合体Bをスパッタリングターゲット組立体として配列する際に、接合体Bに存在する3個のターゲットピース間の分割線が、隣接する分割ターゲットピース間の分割線と同位置にならないように設置することを特徴とするスパッタリングターゲット組立体、を提供する。
一つのスパッタリングターゲット-バッキングプレート接合体Bにおいて、各分割ターゲットピースAの長さの相違が50mm以上であることを特徴とする上記1)記載のスパッタリングターゲット組立体、を提供する。
一つのスパッタリングターゲット-バッキングプレート接合体Bにおいて、各分割ターゲットピースAの長さの相違が100mm以上であることを特徴とする上記1)記載のスパッタリングターゲット組立体、を提供する。
一つのスパッタリングターゲット-バッキングプレート接合体Bのターゲットピース間の分割線と、隣接するスパッタリングターゲット-バッキングプレート接合体Bのターゲットピース間の分割線が平行であり、該隣接する分割線の平行間隔が50mm以上であることを特徴とする上記1)~3)のいずれか一項に記載のスパッタリングターゲット組立体、を提供する。
一つのスパッタリングターゲット-バッキングプレート接合体Bのターゲットピース間の分割線と、隣接するスパッタリングターゲット-バッキングプレート接合体Bのターゲットピース間の分割線が平行であり、隣接する分割線の平行間隔が100mm以上であることを特徴とする上記1)~3)のいずれか一項に記載のスパッタリングターゲット組立体、を提供する。
一つのスパッタリングターゲット-バッキングプレート接合体Bに使用される3個以上の矩形のターゲットピースAが、他のスパッタリングターゲット-バッキングプレート接合体Bの3個以上の矩形のターゲットピースAと同一寸法のターゲットピースAからなることを特徴とする上記1)~5)のいずれか一項に記載のスパッタリングターゲット組立体、を提供する。
これはFPD用スパッタリングターゲットとして好適であり、パーティクルの発生が少なく、歩留まりを向上させることができる大型のスパッタリングターゲットアッセンブリの主たる要件を満たすものである。
このように、本発明ではターゲットピースの長さを変え、ターゲットを並べた時のターゲットピース間の分割線がずれるように組み合わせたターゲット-バッキングプレート接合体で、ずれるように組み合わせることで、分割線の部分に起因するパーティクルを分散させ歩留まりを向上することが可能となる。
ターゲットの生産性から見ると、同形状のターゲットピースAであることが望ましいと言える。異形状のターゲットピースの製造は、製造コストを増加させる原因となるからである。本願発明は、上記の通り3種類以上とすることを提案するが、これらは、いずれも矩形であり、上記特許文献に示すような、煩雑さと製造コストの増加を招くことがないという利点を有する。
また、矩形のターゲットピースAを、異なる寸法の矩形のターゲットピースA1、A2、A3、A4の4種類を作製し、これらをバッキングプレートに配列して接合した場合、その組み合わせの一として、ターゲットピースA1、A2、A3、A4という配列、その組み合わせの二として、ターゲットピースA2、A3、A4、A1という配列、その組み合わせの三として、ターゲットピースA3、A4、A1、A2という配列、その組み合わせの四として、ターゲットピースA4、A1、A2、A3という配列が可能である。
200mm×1500mmのターゲット板を長さ300mm、500mm、700mmの長さのピースの張り合わせにより、図1に示すようにバッキングプレート上に接合して、3種のスパッタリングターゲット-バッキングプレート接合体を作製し、そしてスパッタリングターゲット-バッキングプレート接合体の組み合わせにより、図1の左側の図に示すように、これらを3セット並べた時、ターゲットピース間の分割線がずれるようにX、Y、Zにセットしてスパッタリングターゲット組立体とした。必要に応じて、このX、Y、Zセットを繰り返すことができる。
200mm×1500mmのスパッタリングターゲット板を、同一長さ500mmのピースA43個で、各バッキングプレート上に接合して作製し、これを3枚/セットとしてスパッタリングターゲット組立体とし、これをスパッタリング装置に装着した。そして、このターゲットを用いて1300mm×1500mmのガラス基板に成膜した。そして実施例と同様のパーティクル比較を行った。
図2に、バッキングプレートに、同寸法のターゲットピースを配列したターゲット-バッキングプレート接合体とパーティクルの発生状況を示す。図2の右側に示すように、ターゲットピース間の分割線に相当する領域におけるパーティクル数が28ヶ、29ヶと高く、この領域は製品として使用できなかった。
