摘要
主要介绍一种统计筛选实验方法,能快速找到对工艺影响最大的工艺参数,从而缩短工艺评估周期,这些参数包括:前烘温度、胶厚、PEB温度、显影温度、显影时间、显影波浓度、显影搅动。
The paper introduces a statistically designed screening experimental method which can lead to a much shorter process evaluation cycle,and determine the most significant process factors. The process factors include:softbake temperature,resist coat thickness, post exposure bake temperature, develop temperature, develop time, develop concentration, develop agitation.
