    • A platen assembly, a wafer polishing apparatus, and a wafer polishing method are provided to uniformly polish a wafer by precisely controlling pressure applied to a polishing belt. A platen(110) supports a polishing belt for polishing a wafer to prevent the polishing belt from hanging down during polishing the wafer. Plural first bladder(120) are extended along a first direction in the entire region on an upper surface of the platen. The bladders are arranged to be separated each other in a regular interval. The bladders pressurize the polishing belt. Plural second bladders(130) are extended along the first direction in a middle region between a center region and an edge region of the upper surface of the platen. The bladders are arranged between the first bladders. The second bladders pressurize the polishing belt.
    • 提供压板组件,晶片抛光装置和晶片抛光方法,以通过精确地控制施加到抛光带的压力来均匀地抛光晶片。 压板(110)支撑用于抛光晶片的抛光带,以防止抛光带在抛光晶片期间垂下。 多个第一囊(120)沿着压板的上表面上的整个区域中的第一方向延伸。 气囊被布置为以规则的间隔彼此分离。 气囊对抛光带加压。 多个第二气囊(130)在压板的上表面的中心区域和边缘区域之间的中间区域中沿第一方向延伸。 气囊布置在第一个囊之间。 第二个气囊对抛光带加压。
