    • The present invention relates to a retainer ring used in a chemical mechanical polishing device. The retainer ring is generally attached to a polishing head assembly to perform a chemical and mechanical polishing process (CMP) and configured to easily supply a slurry on a surface of a wafer to be polished while maintaining the wafer to be polished during a chemical mechanical polishing process. Accordingly, the retainer ring includes a projection to maintain a wafer during the CMP process and a groove to supply the slurry. When the slurry is flown onto a polishing pad, an oil film of the slurry is formed on an entire surface of the polishing pad, and the slurry may reach the wafer through the groove of the retainer ring. Accordingly, most of the slurry is discharged due to centrifugal force without contributing to the polishing process. Different from an existing scheme to supply a slurry from an outside of a retainer ring during the chemical mechanical polishing process, the present invention supplies the slurry to an inside of the retainer ring and improves a used efficiency of the slurry in such a way that the slurry is supplied to an inside of the retainer ring and a slurry spilling prevention ring is formed at a peripheral portion of the retainer ring to prevent the slurry from being discharged.
    • 本发明涉及一种用于化学机械抛光装置的保持环。 保持环通常附接到抛光头组件以执行化学和机械抛光工艺(CMP),并且被配置为在化学机械抛光期间保持要抛光的晶片在待抛光的晶片的表面上容易地供应浆料 处理。 因此,保持环包括在CMP工艺期间保持晶片的突起和用于供应浆料的槽。 当浆料流到抛光垫上时,在抛光垫的整个表面上形成浆料的油膜,浆料可以通过保持环的凹槽到达晶片。 因此,大部分浆料由于离心力而排出,而不会对抛光过程产生影响。 与在化学机械抛光过程中从保持环的外部供应浆料的现有方案不同,本发明将浆料供应到保持环的内部,并且以这样的方式提高浆料的使用效率: 浆料被供给到保持环的内部,并且在保持环的周边部分处形成有防止淤泥溢出的环,以防止浆料被排出。
