- the abrasive is thrown away, it is difficult to increase the abrasive supply flow rate due to cost problems, but there is an advantage that the quality is easily stabilized because the concentration is constant.
- the polishing machine is provided with a waste liquid receiver for collecting used abrasives. Since the waste liquid receiver collects the slurry scattered by the rotation of the surface plate, it becomes larger than the surface plate size as disclosed in Patent Document 1. Further, Patent Document 2 discloses a polishing apparatus designed to collect only a portion where slurry is scattered. However, the polishing apparatus as in Patent Document 2 also requires a waste liquid receiver having a size larger than the swing width because the surface plate swings in the horizontal direction by the swing mechanism.

Accordingly, the area of the waste liquid receiver can be reduced regardless of the presence or absence of the swing of the surface plate and the size of the surface plate, so that mixing of the polishing solution can be suppressed and recovery efficiency can be improved. Further, since the relative position with respect to the surface plate does not change due to the swinging of the surface plate, maintenance work such as cleaning of the waste liquid receiver does not become difficult depending on the position of the surface plate. Therefore, the time required for the maintenance work can be shortened, and the apparatus stop time can be shortened.

- the separator 11 for example, the same material as a conventional separator as shown in FIG. 10 can be used.
- polishing is performed by sliding the surface of the wafer W held by the polishing head 4 in sliding contact with the polishing pad 2 while circulating the polishing agent in this way.
- polishing agent is difficult to mix with other solutions even if the polishing agent is circulated and reused. Accordingly, it is difficult to dilute the polishing agent, and the fluctuation of the polishing rate can be suppressed. Moreover, since the amount of the abrasive that cannot be reused due to mixing with other solutions can be reduced, the cost of the abrasive can be reduced.
- Example 2 A silicon wafer having a diameter of 300 mm was polished while the abrasive was circulated and reused using the polishing apparatus of the present invention.

- a stay is attached to the lower part of the surface plate 3, and a waste liquid receptacle 7 made of vinyl chloride is fixed to the surface plate 3. Since the waste liquid receiver swings together with the surface plate, the area of the waste liquid receiver could be reduced to a size that does not overflow at the maximum polishing flow rate. As a result, the area (area occupied by the plane) of the waste liquid receiver was 68.3 mm 2 , which was reduced to about 1/5 of the comparative example described later. In the example, in order to suppress the mixing of the polishing liquid and improve the recovery efficiency, an inclination is provided inside the waste liquid receiver.
- condition 1 In condition 1, the separator line was switched at a timing such that the amount of abrasive in the tank did not decrease. Under these conditions, pure water is mixed with the abrasive, the abrasive is diluted, and the polishing rate tends to decrease. When the variation of the polishing rate was examined, as shown in FIG. 4, in the example, the decrease in the polishing rate was suppressed to 7%. In FIG. 4, the polishing rate of each batch is a relative value to the polishing rate of the first batch.
- Condition 2 In condition 2, the separator was switched at a timing when pure water was not mixed with the abrasive. Under this condition, the amount of abrasive discharged tends to increase. The discharged amount was determined from the remaining amount of the slurry tank after 10 batches of continuous polishing. As a result, as shown in FIG. 5, the amount of abrasive discharged in the example was 38%.
- the area of the waste liquid receiver (plane occupation area) was 307.3 mm 2 . Due to the swinging width, the area could not be further reduced.
- an inclination is provided inside the waste liquid receiver.
- the polishing rate was reduced by 24% in the comparative example. As described above, the polishing rate was greatly reduced as compared with the Example.

Abstract
Description
本発明の研磨装置を用いて研磨剤を循環させ再使用しながら、直径300mmのシリコンウェーハの研磨を行った。また、研磨装置は、3つの定盤を有し、1定盤当たり2つの研磨ヘッドを持つインデックス方式の研磨装置を用いた。定盤の直径は800mmであった。
条件1では、タンク内の研磨剤量が低下しないようなタイミングで、セパレーターのライン切り換えを行った。この条件では、研磨剤に純水が混合し、研磨剤が希釈され、研磨レートが低下しやすい。研磨レートの変動を調べたところ、図4に示すように、実施例では、研磨レートの低下は7%に抑制された。なお、図4では、各バッチの研磨レートは、1バッチ目の研磨レートに対する相対値としている。
また、条件2では、研磨剤に純水が混合しないタイミングでセパレーターの切り換えを行った。この条件では、研磨剤の排出量が増加しやすい。10バッチの連続研磨後のスラリータンクの残量から、排出量を求めた。その結果、図5に示すように、実施例の研磨剤の排出量は38%となった。
廃液受けを定盤に固定していない従来の研磨装置を用いたこと以外、実施例と同様な条件で実施例と同様に研磨レート及び研磨剤の排出量を評価した。比較例で用いた研磨装置は、図6、7に示すように、廃液受け107が、定盤103に固定されていないため、定盤103の揺動により廃液受け107と定盤103の相対位置が変化する。よって、定盤位置に関わらず研磨剤を回収するためには、廃液受けの面積を大きくすることが必須である。比較例における定盤サイズと揺動幅の場合を考慮した結果、廃液受けの面積(平面占有面積)は307.3mm2となった。揺動幅の問題で、これ以上面積を小さくすることはできなかった。なお、実施例と同様に、研磨液の混合を抑制し、回収効率を改善するため、廃液受け内部に傾斜を設けている。
