    • The present invention provides a polishing apparatus and a polishing method which may obtain a maximum polishing capability with a minimum amount of a polishing liquid supplied onto a polishing pad by using a polishing liquid storage mechanism provided on the polishing pad to store the polishing liquid which has been used for polishing and retains a sufficient polishing capability without discharging the polishing liquid maintaining sufficient polishing capability after the polishing liquid is used for the polishing, and by measuring the polishing capability of the polishing liquid and quickly discharging the polishing liquid whose the polishing capability is lowered. The polishing apparatus includes: a polishing liquid storage mechanism (10) to store the polishing liquid on the polishing pad (2) by damming the polishing liquid; a polishing liquid sensor (S) measuring a physical quantity representing the freshness of the polishing liquid that is stored by the polishing liquid storage mechanism (10); a freshness measuring instrument (5) to calculate the freshness of the stored polishing liquid from the physical quantity measured by the polishing liquid sensor; and a freshness controller (6) to control supply states of the polishing liquid and/or the storage state of the polishing liquid, based on the freshness of the polishing liquid that is determined by the freshness measuring instrument (5).
    • 本发明提供一种抛光装置和抛光方法,其可以通过使用设置在抛光垫上的抛光液体存储机构,以最少量的抛光液体供给到抛光垫上来获得最大抛光能力,以存储具有 被用于抛光并保持足够的抛光能力,而不会在抛光液用于抛光后保持足够的抛光能力而抛光抛光液,并且通过测量抛光液的抛光能力并快速地排出研磨液的抛光能力 降低。 抛光装置包括:抛光液体存储机构(10),其通过阻止抛光液体将抛光液体存储在抛光垫(2)上; 抛光液体传感器(S),其测量表示由所述研磨液储存机构(10)储存的所述研磨液的新鲜度的物理量; 新鲜度测量仪器(5),用于根据由抛光液体传感器测量的物理量来计算所储存的抛光液的新鲜度; 以及基于由新鲜度测量仪器(5)确定的抛光液体的新鲜度来控制抛光液的供给状态和/或抛光液的储存状态的新鲜度控制器(6)。

    • This invention provides a CMP polishing method that, when a hydrophobilized porous material is used as an interlayer insulation film material for a semiconductor integrated circuit formed on a substrate, after washing and removal of a slurry and a polishing residue, which stay on the substrate surface, with a surfactant-containing washing liquid, an organic material permeated in the interlayer insulation film can be efficiently removed. When washing is carried out with a washing liquid containing a surfactant to remove the residual slurry and polishing residue, the organic material contained in the surfactant-containing washings is permeated in the interlayer insulation film (3). Thereafter, the substrate is washed with an organic solvent or an organic solvent-containing solution to wash away the organic material permeated in the interlayer insulation film (3). Although the interlayer insulation film (3) is in a hydrophobilized state, since the organic solvent is used for the washing, the organic material permeated in the interlayer insulation film (3) can be dissolved and washed away without being influenced by the hydrophobilized state.
    • 本发明提供一种CMP抛光方法,其中使用疏水化多孔材料作为形成在基板上的半导体集成电路的层间绝缘膜材料,在清洗和除去留在基板表面上的浆料和抛光残渣之后 通过含有表面活性剂的洗涤液,可以有效地除去透过层间绝缘膜的有机材料。 当用含有表面活性剂的洗涤液进行洗涤以除去残留的浆料和抛光残渣时,含有表面活性剂的洗涤液中含有的有机材料渗透在层间绝缘膜(3)中。 此后,用有机溶剂或含有机溶剂的溶液洗涤基板,以冲洗渗透在层间绝缘膜(3)中的有机材料。 尽管层间绝缘膜(3)处于疏水化状态,但是由于使用有机溶剂进行洗涤,渗透在层间绝缘膜(3)中的有机材料可以溶解并洗涤而不受疏水化状态的影响。
