论文摘要
在本文中,研究了对最先进的晶圆夹的压电实施。目的是提出和验证一种解决方案方法,其中包括机械设计和控制系统,以至少对晶圆夹的两个特征模量进行至少5%的阻尼。该目标是“概念证明”,以表明将最新的阻尼方法实施到工业应用中,而该方法又可以用来抑制不同的薄薄结构。压电及其宿主结构之间的耦合关系用于设计压电贴片的放置,以及一个最先进的晶圆夹具的模态分析数据。这些数据是通过实验设置来衡量的。主动阻尼已被成功地实现在晶圆夹上,其中正位置反馈(PPF)用作对照算法来抑制两个特征模。
In this paper the implementation of piezoelectrics to a state-of-the-art wafer gripper is investigated. The objective is to propose and validate a solution method, which includes a mechanical design and control system, to achieve at least 5% damping for two eigenmodes of a wafer gripper. This objective serves as a 'proof of concept' to show the possibilities of implementing a state-of-the-art damping method to an industrial application, which in turn can be used to dampen different thin structures. The coupling relation between the piezoelectrics and their host structure were used to design the placement of the piezoelectric patches, together with modal analysis data of the a state-of-the-art wafer gripper. This data had been measured through an experimental setup. Active damping has been succesfully implemented onto the wafer gripper where positive position feedback (PPF) is used as a control algorithm to dampen two eigenmodes.
