摘要： PROBLEM TO BE SOLVED: To provide a method for controlling the shape of a bevel portion of a wafer, minimizing deformation of a retainer ring during a CMP step. SOLUTION: In the method for controlling the shape of a bevel portion, the bevel portion of a wafer W is polished to form a flat end face B1 before polishing the wafer W using a CMP device. Deformation of a retainer ring of the CMP device by the wafer W is prevented thereby. Here, a width D of the end face B1 is preferred to be within 200-500 μm. As a means for forming the end face B1, a bevel polishing device which uses a polishing tape or the like is employed. COPYRIGHT: (C)2010,JPO&INPIT
摘要翻译：要解决的问题：提供一种用于控制晶片的斜面部分的形状的方法，使CMP步骤期间保持环的变形最小化。解决方案：在用于控制斜面部分形状的方法中，使用CMP装置对晶片W进行研磨之前，抛光晶片W的斜面部分以形成平坦端面B1。因此防止了由晶片W造成的CMP装置的保持环的变形。这里，端面B1的宽度D优选在200〜500μm之间。作为形成端面B1的手段，采用使用研磨带等的斜面研磨装置。版权所有（C）2010，JPO＆INPIT
