Author Affiliations +
Although various approaches can be used to quantify linewidth roughness (LWR), it is essential to determine it with sufficient confidence. Statistical fluctuations inherent to the measurement process are making correlation between performance and LWR challenging. To reduce uncertainty, line width variations and LWR need to be monitored online in full automation by CDSEM. In this paper, we use this methodology to investigate the effect of LWR on electrical performance for various device applications. Our results quantify the impact of LWR by using matching techniques.
