Abstract

PROBLEM TO BE SOLVED: To provide an abrasive-grain-fixed wire saw having good sharpness and less kerf loss.SOLUTION: A wire saw is dispersion-anchored with a grain aggregate on its surface. The grain aggregate consists of main grains in a predetermined grain diameter range functioning as an abrasive grain for grinding a material and auxiliary grains smaller in grain size than the main grains. In a number-based integration distribution of the grain aggregate, the accumulation% of the auxiliary grains is at least 11% of the accumulative grain number from the small-sized side of the number-based integration distribution.

Description

本発明は、シリコンやセラミック、サファイヤなどの硬質材料の切断に使用されるワイヤソーに関する。   The present invention relates to a wire saw used for cutting hard materials such as silicon, ceramics, and sapphire.

この種のワイヤソーは、従来より、例えば半導体用のシリコンウエハーやLED用途におけるサファイアなどの他、セラミックや石材のように、硬質で脆性特性の大きい難加工材の切断加工に使用されてきた。   Conventionally, this type of wire saw has been used for cutting hard and difficult-to-work materials such as ceramics and stones, as well as silicon wafers for semiconductors and sapphire in LED applications.

以前は、研磨剤とクーラントを配合したスラリーを用いながら切断を行う、いわゆる砥粒遊離式のワイヤソーが主流であったが、砥粒遊離式のワイヤソーは、スラリーをサンプルに供給しながら切断しなければならないことから作業性が良くなかった。それに加えて、切断の際に、スラリーと切り粉の混合物であるスラッジが発生するため、作業環境の悪化を招くだけでなく、切断後にはそのスラッジをサンプルから除去するためにサンプルを洗浄する必要もあり、環境面でもコスト面でも効率が悪かった。   In the past, so-called abrasive-free wire saws that were cut using a slurry containing abrasive and coolant were the mainstream, but abrasive-free wire saws must be cut while supplying the slurry to the sample. The workability was not good because it was necessary. In addition, sludge, which is a mixture of slurry and swarf, is generated during cutting, which not only degrades the working environment but also requires the sample to be washed after cutting to remove the sludge from the sample. There were also environmental and cost inefficiencies.

このような課題点を解消するために、砥粒固定式のワイヤソーが開発されている。砥粒固定式のワイヤソーは、切れ味が極めて良好であり、スラリーが不要であり、機械とその周辺の汚染を低減することができ、作業環境を改善することができるという利点を有する。また、数百mまたは数十km以上の長尺のダイヤモンドワイヤソーを製作することができるので、多くの枚数のウエハーを一度でスライシング加工することが可能であるので、スラリーを用いる砥粒遊離式のワイヤソーに比べて数倍以上の切断速度を得ることができる。   In order to solve such problems, an abrasive fixed wire saw has been developed. An abrasive-fixed wire saw has the advantage that the sharpness is extremely good, no slurry is required, contamination of the machine and its surroundings can be reduced, and the working environment can be improved. In addition, since a diamond wire saw having a length of several hundred meters or several tens of kilometers or more can be manufactured, a large number of wafers can be sliced at one time. Cutting speeds several times higher than wire saws can be obtained.

近年ではこのような砥粒固定式のワイヤソーの性能向上を図るべく、多くの提案がされており、例えば、砥粒の粒径を、ある一定の一つの範囲内に収め、且つ砥粒を芯線に分散固着させる層をある一定の厚みにすることにより、切れ味を向上させるような方法が提案されている(特許文献1参照)。これにより、切れ味のよいワイヤソーが得られるのは確かであるが、切断の対象はシリコンウエハーなどのような、精密機器に使用される繊細な部品であるため、より切れ味がよく、よりカーフロスの少ないワイヤソーが求められているのが実情であった。   In recent years, many proposals have been made to improve the performance of such wire-fixed wire saws. For example, the particle diameter of the abrasive grains is kept within a certain range, and the abrasive grains are placed in the core wire. There has been proposed a method for improving the sharpness by making the layer to be dispersed and fixed to a certain thickness (see Patent Document 1). Although it is certain that a sharp wire saw can be obtained in this way, the object to be cut is a delicate part used in precision equipment such as a silicon wafer, so it has a better sharpness and less kerf loss. The reality is that a wire saw is required.

上記のような事情に鑑み、本発明の目的とするところは、従来品よりも、より切れ味がよく、カーフロスの少ない砥粒固定式のワイヤソーを提供することにある。   In view of the circumstances as described above, an object of the present invention is to provide an abrasive-fixed wire saw that is sharper and less kerf than the conventional product.

発明者らは、かかる課題を解決すべく鋭意検討を行った結果、粒子群がワイヤの表面に分散固着したワイヤソーであって、前記粒子群は、材料を研削する砥粒として機能する所定粒径範囲の主粒子と、該主粒子より粒径が小さい副粒子とからなり、当該粒子群の個数基準積算分布において、前記副粒子の累積%が、前記個数基準積算分布の小粒子径側からの積算粒子個数の11%以上であるワイヤソーを用いることにより、従来の砥粒工程式のワイヤソーよりも、切れ味がよく、カーフロスの少ない砥粒固定式のワイヤソーを提供することができることを見出すに至った。   As a result of intensive studies to solve such problems, the inventors of the present invention have a wire saw in which the particle group is dispersed and fixed on the surface of the wire, and the particle group has a predetermined particle size that functions as an abrasive for grinding the material. A primary particle in a range and secondary particles having a particle size smaller than the primary particle, and in the number-based cumulative distribution of the particle group, the cumulative percentage of the secondary particles is from the small particle diameter side of the number-based cumulative distribution. By using a wire saw that is 11% or more of the cumulative number of particles, it has been found that it is possible to provide an abrasive-fixed wire saw that is sharper and has less kerf than the conventional abrasive process type wire saw. .

本発明は、粒子群がワイヤの表面に分散固着したワイヤソーであって、前記粒子群は、材料を研削する砥粒として機能する所定粒径範囲の主粒子と、該主粒子より粒径が小さい副粒子とからなり、当該粒子群の個数基準積算分布において、前記副粒子の累積%が、前記個数基準積算分布の小粒子径側からの積算粒子個数の11%以上であるワイヤソーである。   The present invention is a wire saw in which a group of particles are dispersed and fixed to the surface of a wire, and the group of particles has a main particle in a predetermined particle size range that functions as an abrasive for grinding a material, and a particle size smaller than the main particle. The wire saw is composed of secondary particles, and the cumulative percentage of the secondary particles in the number-based cumulative distribution of the particle group is 11% or more of the cumulative number of particles from the small particle diameter side of the number-based cumulative distribution.

以下に、本発明の実施形態を添付図面に基づき説明する。   Embodiments of the present invention will be described below with reference to the accompanying drawings.

図1は、本発明におけるワイヤソーの実施形態を示す側面図である。図1に示すように、本実施形態におけるワイヤソー1は、その基本骨格たる芯線12に、主粒子13及び副粒子14を分散固着させた構成を有する。   FIG. 1 is a side view showing an embodiment of a wire saw according to the present invention. As shown in FIG. 1, the wire saw 1 in the present embodiment has a configuration in which main particles 13 and sub-particles 14 are dispersed and fixed to a core wire 12 that is a basic skeleton thereof.

芯線12は、通常のワイヤソーに使用されるものであればよく、容易に極細線に加工することができ、且つ十分な強度も兼ね備えるという観点から、例えば、ピアノ線が好ましい。ピアノ線の材質としては、はんだの溶融温度により強度が劣化しない種々の金属ワイヤを用いることができ、鉄、ニッケル、コバルト、クロム、タングステン、モリブデン、銅、チタン、アルミニウム及びそれらの合金のいずれかからなるものが好適である。特に、ピアノ線を含む高炭素鋼からなるものが安価且つ安定して入手でき、コスト低減できる点で好ましい。その他、ピアノ線以外であっても、炭素繊維、アラミド繊維、ボロン繊維、ガラス繊維のいずれか1種の単線または撚り線を用いてもよい。芯線2の径は50〜200μmが好ましい。   The core wire 12 may be any wire used for a normal wire saw, and is preferably a piano wire, for example, from the viewpoint that it can be easily processed into an ultrafine wire and has sufficient strength. As the material of the piano wire, various metal wires whose strength does not deteriorate due to the melting temperature of the solder can be used, and any one of iron, nickel, cobalt, chromium, tungsten, molybdenum, copper, titanium, aluminum and alloys thereof The one consisting of is preferred. In particular, those made of high carbon steel including piano wire are preferable in that they can be obtained inexpensively and stably, and the cost can be reduced. In addition, a single wire or a stranded wire of any one of carbon fiber, aramid fiber, boron fiber, and glass fiber may be used other than the piano wire. The diameter of the core wire 2 is preferably 50 to 200 μm.

ワイヤソー1に分散固着させる粒子群の粒度分布曲線を作成した場合、その粒子径により、主粒子13と副粒子14に大別される。主粒子13の粒子径は5〜60μmの範囲にあるのが好ましく、そのメジアン径は8〜50μmが好ましい。一方、副粒子14の粒子径は0.1〜3μmの範囲にあるのが好ましく、そのメジアン径は0.5〜2μmが好ましい。そして、主粒子13のメジアン径及び副粒子14のメジアン径の関係においては、副粒子14のメジアン径が、主粒子13のメジアン径の30%以下、より好ましくは15%以下、更に好ましくは8%以下にするのがよい。   When a particle size distribution curve of a particle group dispersed and fixed to the wire saw 1 is created, the particle group is roughly divided into a main particle 13 and a sub particle 14 depending on the particle diameter. The particle diameter of the main particles 13 is preferably in the range of 5 to 60 μm, and the median diameter is preferably 8 to 50 μm. On the other hand, the particle diameter of the secondary particles 14 is preferably in the range of 0.1 to 3 μm, and the median diameter is preferably 0.5 to 2 μm. And in the relationship between the median diameter of the main particles 13 and the median diameter of the sub-particles 14, the median diameter of the sub-particles 14 is 30% or less, more preferably 15% or less, more preferably 8% of the median diameter of the main particles 13. % Or less is recommended.

主粒子13は、例えばシリコン等の切断対象物を切断する際に、砥粒として機能する。一方で副粒子14は、切断自体に直接寄与するわけではないが、ワイヤソーの表面積を増大させることにより、並びに、ワイヤソー表面に凹凸を形成することで、切断時に使用するクーラントの連れ持ち量を増やすことにより、ワイヤソーの切れ味向上やカーフロス減少に寄与すると考えられる。   The main particles 13 function as abrasive grains when cutting an object to be cut such as silicon. On the other hand, the secondary particles 14 do not directly contribute to the cutting itself, but by increasing the surface area of the wire saw and forming irregularities on the surface of the wire saw, the carry amount of the coolant used at the time of cutting is increased. This is thought to contribute to improving the sharpness of the wire saw and reducing kerf loss.

副粒子14の小粒子径側からの積算粒子数は、砥粒全体の粒子数に対して、11%以上であればよく、40%以上がより好ましい。こうすることにより、従来のワイヤソーに比して切れ味がよく、カーフロスの少ないワイヤソーを得ることができる。   The cumulative number of particles from the small particle diameter side of the sub-particles 14 may be 11% or more, and more preferably 40% or more with respect to the number of particles of the entire abrasive grains. By doing so, it is possible to obtain a wire saw having a better sharpness and less kerf loss than a conventional wire saw.

主粒子13は、例えばダイヤモンド、CBN等の、いわゆる超砥粒にニッケル、ニッケルーリン合金の金属膜がコーティングされた構成を有する。一方、副粒子14は、主粒子13と同様の構成でも良ければ、ダイヤモンド、CBNであっても良いし、ニッケルやニッケルーリン合金であっても良いし、若しくはこれらの混合物であっても良い。   The main particles 13 have a configuration in which a so-called superabrasive such as diamond or CBN is coated with a metal film of nickel or a nickel-phosphorus alloy. On the other hand, the secondary particles 14 may have the same configuration as the main particles 13, may be diamond, CBN, nickel, nickel-phosphorus alloy, or a mixture thereof.

主粒子13及び副粒子14からなる粒子群を芯線12に分散固着させる際には、例えばレジボンドによる方法、電着による方法、ロー付けによる方法など、従来より使用されている公知の方法によって分散固着させるとよいが、ワイヤソーとして使用するにあたって十分な砥粒の保持力を有していればよく、これらに限定されない。   When the particle group consisting of the main particles 13 and the sub-particles 14 is dispersed and fixed to the core wire 12, it is dispersed and fixed by a conventionally known method such as a method using a resist bond, a method using electrodeposition, or a method using brazing. However, the present invention is not limited to this as long as it has a sufficient holding power for abrasive grains when used as a wire saw.

この際に、主粒子13と副粒子14を別々に芯線12に分散固着させても良いが、工程数を少なくするという観点からは、両粒子を混合してから分散固着させるのが望ましい。但し、いずれの手順で分散固着させたとしても、主粒子13及び副粒子14がそれぞれ偏りなく芯線全体に分散固着するようにする必要がある。   At this time, the main particles 13 and the sub-particles 14 may be separately dispersed and fixed to the core wire 12. However, from the viewpoint of reducing the number of steps, it is desirable to mix and fix both particles. However, it is necessary to disperse and fix the main particles 13 and the sub-particles 14 to the entire core wire without any deviation regardless of the procedure.

このようにして得られるワイヤソーは、切れ味が良く、カーフロスも少ないので、高硬度の部材を薄く切断するのに適している。   The wire saw thus obtained has good sharpness and little kerf loss, and is suitable for thinly cutting a high-hardness member.

例えば、太陽電池パネルや半導体製造に必要となるシリコンウエハを得るためには、ケイ素の結晶からなる硬度の高いインゴットを薄く切断する必要があり、本発明に係るワイヤソーはこのような用途に用いることが可能である。一般的に単結晶性シリコンの方が太陽電池や半導体を製造した際に高性能のものが得られる。しかし近年では、広大な面積の太陽電池パネルの需要増大に伴い、安価にシリコンウエハを得るために、多結晶性シリコンからなるインゴットからシリコンウエハを得ることが多くなっている。本発明に係るワイヤソーは単結晶性のシリコンからなるインゴットの切断には勿論、多結晶性シリコンからなるインゴットの切断にも、適している。   For example, in order to obtain a silicon wafer necessary for manufacturing a solar cell panel or a semiconductor, it is necessary to thinly cut a hard ingot made of silicon crystals, and the wire saw according to the present invention is used for such a use. Is possible. In general, single crystalline silicon can be obtained with high performance when a solar cell or a semiconductor is manufactured. However, in recent years, with an increase in demand for solar cell panels having a large area, in order to obtain a silicon wafer at a low cost, a silicon wafer is often obtained from an ingot made of polycrystalline silicon. The wire saw according to the present invention is suitable not only for cutting an ingot made of monocrystalline silicon but also for cutting an ingot made of polycrystalline silicon.

以下、実施例に基づき、本発明の実施形態をより具体的に説明するが、本発明がこれらに限定されるものではない。   Hereinafter, based on an Example, Embodiment of this invention is described more concretely, This invention is not limited to these.

(実施例1)
ニッケルコートダイヤモンド砥粒にニッケル微粉を添加し、ワイヤソー芯線の表面に分散固着させるための粒子群を得た。その粒子群を、フロー式粒子群分析装置により個数基準粒度分布の計測を行ったところ、図2に示すように、主粒子と副粒子による2つのピークを有するような個数基準粒度分布が得られた。その後、前記粒子群を芯線に分散固着させ、ワイヤソーを得た。
Example 1
Nickel fine powder was added to nickel-coated diamond abrasive grains to obtain a particle group for dispersing and fixing to the surface of the wire saw core wire. When the particle group was subjected to measurement of the number-based particle size distribution using a flow type particle group analyzer, a number-based particle size distribution having two peaks of main particles and sub-particles was obtained as shown in FIG. It was. Thereafter, the particle group was dispersed and fixed to the core wire to obtain a wire saw.

(比較例1)
ニッケルコートダイヤモンド砥粒に実施例1と同様の方法により、ワイヤソー芯線の表面に分散固着させるための粒子群を得た。そして実施例1と同様の方法により個数基準粒度分布の計測を行ったところ、図3に示すように、主に10μm以上の粒径からなる主粒子による1つのピークのみを有するような個数基準粒度分布が得られた。その後、実施例1と同様の方法により、ワイヤソーを得た。
(Comparative Example 1)
By a method similar to that in Example 1, a particle group for dispersing and fixing to the surface of the wire saw core wire was obtained on the nickel-coated diamond abrasive grains. Then, when the number-based particle size distribution was measured by the same method as in Example 1, as shown in FIG. 3, the number-based particle size having only one peak due to the main particles mainly having a particle size of 10 μm or more. A distribution was obtained. Thereafter, a wire saw was obtained in the same manner as in Example 1.

(評価1:表面粗さ評価試験)
実施例1及び比較例1のワイヤソーを使用し、多結晶性のシリコンウエハの切断を行い、切断面の表面粗さの測定を、株式会社東京精密製表面粗さ測定器(型番:サーフコム1500D×3)を用い、中心平均粗さRa及び十点平均粗さRzを測定、算出した。尚、実施例1及び比較例1のそれぞれのワイヤソーにより得られた一の切断面から、3箇所のRa値及びRz値を測定し、その平均値を算出した。
(Evaluation 1: Surface roughness evaluation test)
Using the wire saws of Example 1 and Comparative Example 1, a polycrystalline silicon wafer was cut, and the surface roughness of the cut surface was measured using a surface roughness measuring instrument manufactured by Tokyo Seimitsu Co., Ltd. (model number: Surfcom 1500D × 3), the center average roughness Ra and the ten-point average roughness Rz were measured and calculated. In addition, Ra value and Rz value of three places were measured from one cut surface obtained by each wire saw of Example 1 and Comparative Example 1, and the average value was calculated.

Figure 2014058014
Figure 2014058014

表1に示したように、実施例1の表面粗さは比較例1の表面粗さよりもRa値及びRz値の双方において低値を示した。これは実施例1において、切断面表面の凹凸がより少ないということになり、切断の際にワイヤソーがスムーズにシリコンウエハを切断していった様子が伺え、ワイヤソーの切れ味の良さを示唆するものであると考えられる。また、このように切断面表面の凹凸が少ないということは、それだけ切断方向からぶれることなくワイヤソーが移動したと考えられ、切断時におけるカーフロスも極力抑えられているものと考えられる。   As shown in Table 1, the surface roughness of Example 1 was lower in both Ra value and Rz value than the surface roughness of Comparative Example 1. In Example 1, this means that the surface of the cut surface has less irregularities, and it can be seen that the wire saw smoothly cut the silicon wafer during cutting, suggesting the sharpness of the wire saw. It is believed that there is. In addition, the fact that the surface of the cut surface has less unevenness is considered that the wire saw has moved without being displaced from the cutting direction, and the kerf loss during cutting is also suppressed as much as possible.
