    • PURPOSE: A wafer polishing apparatus is provided to store the large amount of slurry in an intermediate area between a hollow and an outside of a pad and to store the large amount of slurry in a center part of the groove in comparison with an end part of the groove. CONSTITUTION: A wafer polishing apparatus includes a pad. The pad includes a hollow which is formed therein. A plurality of grooves are formed on an upper surface of the pad. The grooves are extended from the hollow to the outside of the pad. The width of the center part of the groove is larger than the width of the end of the groove.

    • A method for controlling wafer flatness using a seasoning plate is provided to control the water flatness in an optimized sate by monitoring a wafer shape after both sides polishing process. A both sides polishing process is performed by using a both sides polishing device including an upper plate, a lower plate, and a wafer carrier. The wafer is monitored. The seasoning plate made of the ceramic material is interposed between the upper plate and the lower plate. The pressure pressing the seasoning plate, the seasoning time, and the abradant temperature are set based on the shape of the monitored wafer. The flatness of the polishing pad is regular by pressurizing the seasoning plate.
    • 提供使用调味板控制晶片平整度的方法,通过在双面抛光处理之后监视晶片形状来控制优化状态下的水平面度。 通过使用包括上板,下板和晶片载体的两面研磨装置进行双面研磨处理。 监测晶圆。 由陶瓷材料制成的调味板介于上板和下板之间。 基于所监测的晶片的形状设定按压调味板的压力,调味时间和研磨温度。 抛光垫的平面度通过对调味板进行加压而规则化。
