摘要:
A method for monitoring the endpoint for a silicon wafer or other semiconductor device CMP process. A fixed abrasive article, such as a three dimensional abrasive article, is used to planarize the wafer in the presence of a working fluid. A component in the effluent from the CMP process is monitored to predict the CMP endpoint. In some embodiments, the component monitored is a reaction production between a component from the silicon wafer and a reactant.
摘要(中):
一种用于监测硅晶片或其它半导体器件CMP工艺的端点的方法。 使用诸如三维磨料制品的固定的磨料制品在工作流体的存在下使晶片平坦化。 监测来自CMP过程的污水中的组分以预测CMP终点。 在一些实施方案中,所监测的组分是来自硅晶片的组分和反应物之间的反应生成。
