    • The present invention provides a method for polishing a layer of material, a method for manufacturing a damascene interconnect structure, and a method for manufacturing an integrated circuit. The method for polishing a layer of material, among other steps, includes obtaining a substrate (310) having a layer of material (330) located thereover, and polishing the layer of material (330) using a polishing surface (410). The step of polishing the layer of material may include subjecting the layer of material (330) to a first polishing process using a first endpoint detection method, the first polishing process removing a portion of the layer of material, and subjecting remaining portions (420) of the layer of material (330) to a second polishing process using a second different optical endpoint detection method.
    • 本发明提供了一种用于抛光材料层的方法,一种用于制造镶嵌互连结构的方法和一种用于制造集成电路的方法。 除了其他步骤之外,用于抛光材料层的方法包括获得具有位于其上的材料层(330)的衬底(310),并且使用抛光表面(410)抛光材料层(330)。 抛光材料层的步骤可以包括使用第一端点检测方法对材料层(330)进行第一抛光工艺,第一抛光工艺移除材料层的一部分,以及对剩余部分(420)进行处理, 使用第二种不同的光学终点检测方法将材料层(330)转移到第二抛光工艺。
