摘要
设计了一种化学机械抛光设备(CMP)的底座系统,主要包括地脚、方钢管、大铝板等。针对CMP设备在使用中存在的噪声偏大,高转速下的电机转动引起的共振影响晶圆抛光质量问题,通过MSC Patran分析软件,对CMP的主要部件——底座系统,进行了振动模态分析,并在此基础上进行了以改变基频为目标的结构优化设计。
Design the pedestal system in Chemical Mechanical Planarization equipment, include the foundation, square steel pipe, big aluminium plate. Aim at noises in using the Chemical Mechanical Planarization equipment, resonance caused by high speed motor which affects the quality of wafers in the process of Chemical Mechanical Planarization. By the MSC Patran software, do modal analysis of vibration of the pedestal system of main parts in CMP equipment, structural optimization was carried out to change the fundamental vibration frequency.
